This is so cool! This all sounded so intimidating to me at the beginning of the video. I mean, a brand new part was put in and still didn't work... I can totally understand why someone (like me) would then suspect the computer was the culprit. A professional garage had this car and they were ready to call the computer. But you used your amazing teaching of simple circuit design to figure out the computer was functioning just fine, the wiring was fine, so the brand new part had to be the culprit. Man, I just love your book! I just finished a couple of days ago reading it all the way through for the third time. I'm actually starting to get this stuff. What seemed so complicated is beginning to seem kind of simple. That's a sign of a good teacher! I was eating lunch in a restaurant after church today and telling someone about your book. Thanks for making what seems so complicated actually understandable!

My friend, your channel has just become a treasure to me. After 4 years trying to diagnose a P0335 code in my Vauxhall Astra which starts & drives perfectly and doing everything but buy a new car to stop it, I am now really getting to learn what 'other' problems might be tricking the computer into believing it's one thing but is in fact emanating from another. As I am analytically minded and interested in engineering etc but not qualified as a mechanic or tech, these are brilliant instructional videos bud, really top draw stuff. The faulty cam sensor video triggering the CKP error was a light bulb moment for me, and one I am now going to start testing for. You know your beans that's for sure.

Thanks Paul, great video. I am a member of your premium channel and have your book. I just want to say this really messed my mind up because in all your lectures you always show the transistor being a part of the PCM and with the cam sensor it is internal to it. I just wanted to point this out because your students may have the same problem understanding the pull up and pull down design when the transistor is moved.

I felt like it was a good time to show the lecture and how much it totally applied to this situation. It is always tough to call a bad new part and knowing circuit design was the key.

This was fantastic! Been fighting this on my 2015 Rubicon for weeks. I'm an Electrical Engineer for an aerospace company, and while the schematics I had were somewhat helpful, your description of the sensor role in-circuit helped out. I was about to relinquish control of the troubleshooting to the dealership, but after watching this, I'm eager to jump back in. After I changed the shocks out, I think something I think I just disturbed something in one of the wiring harnesses. Likely just shorting to an adjacent line. Will post results when I get shop time.

Excellent! When you think about it, (and now I can smugly write this since I watched your class on pull-down signals) its not that hard understanding such a basic concept like pullup/pulldown. You almost feel as if everyone should know this by now (as I said, Im only being clever since I watched your vids, I had no idea that a pull down signal existed before and I sure as hell would have agreed it needed a pcm reflash) but look at what that could have lead to. They were ready to call on a PCM!!! What if this was a 4000$ pcm? And they got it wrong? My goodness, just like you said, its so unbelievably necessary to know the absolute basics. Those "basics" literally saved that guy from a new pcm and additional headaches. All you did was unplug the sensor and understand what that meant. Haha it sounds almost impossible in its simplicity!! Amazing job, Im so glad Im signed up to premium.

I work in an auto parts shop. Recently we identified an issue with 3 different aftermarket suppliers of ignition coil to suit Toyota 3SGE motor where none of them would work in the Altezza yet as far as we know they work fine in every other Toyota that uses that motor. Only genuine would work. The PCM must be extra fussy about feedback signal or current draw in that model.

@williamgrissom9022 2 жыл бұрын
Even in the Chrysler shop manual it is often confusing if the connector diagram is looking at the end of the connector or the backside (or into sensor), plus not always easy to tell which side is the locking tab. Seems they could spell it out better, or perhaps it is in a little footnote somewhere. Looks like this might be the Chrysler 3.8L like in our 2002 minivan. I know that some Jeeps got that (longitudinal version), instead of the 4.0L straight-six. A fine engine, but many Jeep fans berated it. I recall in my minivan the supply voltage is 8 VDC, shared with the crank sensor. The cam sensor looks identical. The 0.6 V you see is about the forward drop of a diode. A transistor is somewhat like two diodes in series, so if one "diode" is failed shorted, you might see a 0.6 V drop when it should be off, but I'll let an EE comment. I do know that transistors most commonly fail shorted.

Paul, I used to work for Federated Auto Parts, and we, along with a lot of other parts stores had a policy that you couldn't return sensors and modules if they had been installed. Have you ever had a problem getting a part replaced after it was bad right out of the box? There is an epidemic of crappy sensors out there these days. At least for my own vehicle, I grab whatever OE sensors I can grab every time I go to the salvage yard, just so I have an OE part to replace them with if they ever go bad. I started doing that after having to put 5 different TPS' on my Durango in 1 year.

Truck ran a little worse, it wasn't until I saw your video where you mentioned getting new parts that were already bad, had that lightbulb 💡 moment, went out, cleaned and scrubbed all the built up gook off the old sensor and boom, no more code.

Pull the sensor, leave connected, 12v test light to the cam sensor signal wire and move your piece of metal past the sensor. light will from on to off. Thanks!

you have to be careful on the type of test light you are using, and with the circuit design as you can pull the signal voltage down to zero through the light and not light the light

thanks! i recently put in a NEW (but bad) CKP sensor and its apparently shorted internally- screwing up my fuel level gauge, ignition coil/ignitor(?) and setting off a host of other selonoids- et al! I cleaned all grounds, rebuilt my fuse box, new ECU, cleaned everything........no changes UNTIL i just now decided to swap back in the old CKP sensor. All the electrical clicking, etc went away immediately and Im not going thru the KEY RELEARN process for the new ECU

Shorted the 5v reference circuit out is what it sounds like. That is rather unfortunate 😕

just wanted to know is there a tiny raised niblet on the trigger wheel to bump the air gap gauge off the end of the sensor.? and that gauge is soluble to oil. ? I guess thats why on the first crank it took tiny bit longer to fire (time to dis-gaurd that air gap gauge. 👍😜🇦🇺

Got a question, I just got done doing a valve cover gasket on 2006 Porsche Cayenne Turbo and when I went to start the engine it threw a engine code P0349... Bank 2 cam shaft positioning sensor... I didn't have this code before. Now I took the sensor out and I see it has a light scratch on it. So I took the cover back off to see if I had broken something but nothing seems to be broken. Any suggestions would be greatly appreciated. Thank you in advance.

What sucks is even when you get OE parts from the dealer and later find out they stopped making them and subbed the refurb's out to Cardone. Had to get an IDM for a 97 F350 with the 7.3 and so far have gotten TWO bad replacements...waiting for a third with our fingers crossed, but either way I don't have faith in a "good" one lasting long at this point.

It would be interesting to do some kind of study looking at "good" vs "bad" new parts on OEM and aftermarket.
@mph5896 5 жыл бұрын
@canuckguy worried OEM does source parts from companies that buy the parts for them. An example would be Delphi making parts for GM. So a Delphi part in some instances would be just as good as an Ac Delco dealer part. Other parts that are aftermarket are just absolute garbage. You can tell just by looking at them an feeling them. They are broken right out of the box. Or may work for a limited amount of time then give up the ghost.

@canuckguy worried I am not sure exactly what you are debating. my original quote was "Cheap parts are a waste of everybody’s time. Go good name brand or oem and save from pulling your hair out". Thats pretty much exactly what you typed here. Go put a Dorman part or a BWD (broke when delivered) on your car and tell me there is no difference.

7/10 sensors I got on my 02 Jeep Grand Cherokee Laredo 4.7L where malfunctioning/junk. It was Bosch O2 sensors, CTS and I bought them over and over getting exchanged only to each of them fail. For whatever reason Denso and Delphi sensors for my Jeep seem to work fine. Oh and Denso Radiator is the actual OE radiator at 1/3 the price of the Mopar sourced one. Just in case anyone has a 90-04 WJ 4.0L I6/4.7L V8 Jeep. Yeah and if I buy them from AutoZone I get bunk sensors sometimes but if I get them from RockAuto of all places they work out of box other than one Ignition coil Delphi that worked great but had it's clip broken in mail. I used high temp engine harness tape to secure the clip in connector of coil on plug. I have the V8

Isn't it the shifting magnetic field which activates the sensor, not the magnetic field? I thought the sensor would react only when you had moving metal close to the sensor

Great video, my Ram ProMaster 2500 started throwing a 0340 yesterday with all the symptoms showing up after 1 day of slow starting as a "pay attention now" warning. Scan shows Bank 1, Sensor 1, so just need to figure out which that is on the 3.6L engine and pick up a sensor. But now I'll have ideas of what else to check if that isn't an immediate fix since I'm multi-meter friendly.

@@ScannerDanner Great suggestion as I do have a code reader. I also seem to be lucky that it is a Ram ProMaster in that I can clearly see both the Camshaft Sensors, so it appears all I have to do is pull the radiator overflow to have enough access for the swap out as opposed to those having to pull the intake manifold. The docs with the new sensor seem to indicate that they should be both replaced to keep them matched - claiming you can get add'l DTCs from mismatch, and that after clearing the codes, there is a "relearn" procedure to do, which I assume just means to rescan for codes? Do you recommend replacing both (at $34 ea. not onerous...) Thanks again.

I remember once a college professor had drawn a resistor (no value) connected to 5V on the white board....alongside was a visible, unconnected ground, reference symbol....(power, resistor, ground) A simple question followed, "What is the voltage on the unconnected end of the resistor?"... Confusion ensued......
@richardcranium5839 5 жыл бұрын
i learned a hard lesson on an intrepid with cam sensor issue . had a miss had cam sensor code. checked power(5v) ground and did ohm meter test from sensor to computer connector. changed sensor ran fine for 2 weeks. then miss came back progressing to a stall. figured pin fitment as they weren't the snuggest. change pigtail. ran good a couple of day then same ole crap. started wiggling harness and in one particular spot it would stall. in their infinite wisdom they put a in harness splice on the 5v tapping the wire to another sensor.(wire welded with no other mechanical means of connection) the torque of the engine would break the supply voltages but i could never get it to act up when i had a meter on it.
@ScannerDanner 5 жыл бұрын
nice find though! And now you know with "pull-down" type circuits, you don't need to measure from the sensor to the computer for continuity right? Just a simple unplug it voltage measurement.

This was a GREAT video Paul thank you! I Just was trying to diagnose a cam sensor on a wrangler today actually but it was on the JK with the 3.6 not the 3.8 you worked on, they now have a dual sensor on each bank its quite interesting actually one sensor for two hall effects! My code was a P0394 which is listed as intermittent. Used my scope and the waveforms looked good at the sensor and at the pins on the PCM and everything else checked out okay...will have to wait for it to come back if it acts up again, hate when that happens but either way I feel good knowing I at least gave it a thorough inspection!
@ScannerDanner 5 жыл бұрын
Something to remember on a pull-down design circuit like these are (even your dual hall effect design). If it measures good at the sensor, there is no need to also check it at the computer. Make sense as to why? Just a time saving tip is all. Now a pull-up design is different and also testing at the computer may be necessary when the signal is good at the sensor.
