Great constructed video, a lot of great information. Actually helped me with the same code, I had a false reading on the maf sensor

I know this is a very old video but man, you are amazing, informal without the fuzz, I have an old Peugeot 307 with the p0170 error code and this is amazing information on my journey to make the car working properly!

Wow complete guide! A bunch of info in the same video :) Keep up the good work.

Great video. I love the explanation of the values on the code reader. I will have to run the reader and write everything down. My car will not start. OBD code reader P0170. Fuel trim Bank 1. I will take plugs out tomorrow. I will get a New air filter.

Wow it worked for me! Thank you so much.

Thank you very much for your nice explanation, your video is very imformative . I have the same OBD code .

Good explain, thanks. I have same error only p0170 at my 607 2.2 phase 1. I will try what you did. What were the values of 02b1s1 and short term after repair?

Thank you. I will try these steps. I have a 06 LR3

Great video.You speak English very good and slow.Very easy to understand. I subscribed to your channel today Looking forward to next video

Great video and am sure I have the same engine. EW10A RFJ. I too have a fuel rich 0170 code. It start after I fit a new coil pack and plugs. (To remove the 0392 coil fault) So i fix one fault and now a new fault! Can new spark plugs cause this? If their electrode gap too large?

well done...i am sure i have the same fault ..holden astra ah...i have similar scan readings to yours..car runs great ..code P0170 only comes up after a couple of days and only comes on at startup never while driving...had previously changed fuel pump and injectors because both those items had problems

Very good video. I just bought a c4 with the ew10a engine and this error and also p1336. I will try your mehtod. Thanks!

excellent video. Keep up the good work. Cheers from Melbourne

Good troubleshooting..

​@Kruuse Car Fix Hello, I have the same error p170 and p172 in my peugeot 407 1.8 16V 125 KM 2010. check engine will always appear on a cold start. I connected the diagnostic device to the OBD and noted the results of the 02 sensor 1 bank 1 at a cold start. Here are the results: for the first few minutes on a cold engine, the values ​​will smell from 0.65V to 1.27V for about 2-3 minutes after starting. then they drop and are in the range of 1.15V to 0.4V for the next 3 minutes. After about 10 minutes of engine operation, the values ​​range from 0.9 V to 0.1 V. The corrections for the first minute are about -24%, then after a few minutes they stop and are below 5%. Do I understand correctly that it may be a matter of a damaged heater? it seems that after heating the exhaust, the voltage values ​​are correct, only deviations from the norm are when the engine (the probe is cold) As for the O2 sensor 2 bank 1 values ​​for less than 2 minutes 1.25V - 0.05V. Then after that time they smell from 0.8V to 0.05V. I am asking for your opinion on what may be the cause of errors and whether such behavior of the O2 sensor 1 bank 1 indicates its failure. After reaching a slightly higher temp, it works perfectly. A great movie that motivated me to self-diagnose. thanks in advance for your reply

Hi there. I have a po170 and po173 codes on my Mitsubishi montero limited 2001. The car idles fine .the check engine light has been on for a long time. What would you suggest I do first? Clean MAF sensor? Replace o2 sensors? I have changed the plugs, wires, intake manifold gaskets and valve cover gaskets. I’m just hoping I can figure it out myself since the shops are so expensive.thx for any suggestions

i have a problem with my peugeot 406 ew10 2001 model with smoke in eyes while driving for some time i change the injector not ok i change ecu not fix on use my pps dainoses and check the parameters ihe only place i saw miss caculator is from map sensor with low reading what could be the course of the low reading on map sensor thank a lot

My car has the same code and I have changed every sensor I can think of and still like it

Thnx for the good expanding. And itz yousfull

Priceless....

Good video thanks

Hello, I have an Opel Astra 2.0T with the Z20let engine. Every few days I get the error P0170 and yesterday I got p0301, temporarily running out of a cylinder. I have the torque pro to see values. What things can I look at?

Great video thanks , i have a question please , what do you mean by closed loop, does it mean that you took the data values while the car idling ?

excellent video thank you. I have the P0170 code and was suspecting the front sensor 1. I was told it might be difficult to take it out tho, if I break it, I'd need to get a new manifold, do you agree with that? Can I test it with the meter before taking it out of car? Hope to hear from you, J

The best video, very well explained, now I have a small idea how the sistems work, I have a petrol 1.4L Peugeot 206 from 2005 A couple of days ago I had AntiPolution Fault and check engine I did an OBD test, removed the fault, the check engine is off, but I still get the code P0170, while the engine is idle and worm My rpms go form 0.8 - 0.7 I can smell some petrol from the exhaust I think as well My O2 S1 shows between 0.1 to 0.8 fluctuating , the O2 S2 is fluctuating between 0.7 - 0.8 I will soon check the other live data to see what I get

Thank you for the details, easy to understand

What if Sensor 2 is bad what would sensor 1 be -/+ in Voltage?

hi, you made a great video i loved it. by the way I have the code p0170 on the same car as in your video 407 2.0i 16v year 2010, I want to know where the problem is directly, thank you.

P0170 golf 4 bytte lamda 2 efter katalysator nu kom koden tillbaka igen, något tips kolla efter? 😀

Hi, Great Video. I have got same error code. change MAP sensor and every thing was fine. after 2 month I had same code. just reset it and after one month I had same code again. Now I do not know exactly what is the reason

Great video! Which obd2 scanner and app are you using?

went to the smog with my Honda Civic 98 and everything passed but the only thing that said failed was something to do with “noX” or “nox” idk exactly what that means or what it is but it was 1300 and it’s limit says it’s suppose to be somewhere in the 700 range

I am having that code po170. On Kia Soul 2010 2.0L. That has 2 o2 sensors. Evidently I will be testing the front sensor. Runs good until engine has warmed up then problems with Rpms up and down. Hopefully that’s the remedy. Thank you

What does a P1174 mean on fuel trim bank 1 mean ?

Hello, What app that you are using for scanning your peugeot using your handphone? I have peugeot 807 2004 EW10J4 engine. It has "anti pollution fault" message on MID and I don't know what cause it. The rpm unstable if in idle. I already replace the throttle body, ignition spark, and coil. But the symptom are the same. Unstable rpm when idling. Thank you for your answer

I love this explanation, but it is very hard for me to find live values. I use obdeleven, I think I over oiled my k&n filter. My car uses two map sensors, I cleaned both. So I assume it would be an o2 sensor. What do you think? I will ofcourse check the live data as far as I can.

have the same code on my astra g 1.6 cabrio. i changed MAF recently but the problem persists. check engine light will be open some days but close some others. Some days the car drives ok but some others feels weird and week and 1st and 2nd gear trembles. I had the ECU checked but they tell me is fine.. Any advise?

What tool or device did you use to get the DataStream ? Those 3 screenshots with all the numbers . Great video

Hello friend, can you help me this subject? i get P0172 error code on my fiat grande punto 2006 gasoline car. I don't still fix it. I changed spark plug, air filter. Don't have any vacuum leak but same trouble continue. Also don't have maf sensor in this cars. It has map sensor. I checked that is clean.

Can you help me ? I have the same code (P0170) on my Opel Corsa C.

I've had a P0170 code fuel trim, it started with revs being inconsistent at idle. Thoughts were misfire as the exhaust sounded like it, so I checked the plugs, they were coated, replaced with new, replaced coil pack, done a service cleaned out throttle body, all hoses clean, air, oil, oil change, m.a.f sensor change, still does it... In fact i drove it around the block, engine cut out 3 times.. I'm thinking it's possibly a crankshaft sensor.. any advice appreciated.

Vacuum leaks and clogged fuel hose are two of the many examples you mentioned will cause lean po171 and po174, not po170 and po171 rich. Of the numerous things you mentioned for causes you forgot to mention the ball-bearing and the thrust washer in the muffler. I'm willing to bet that if this car had a problem, it didn't get fixed for those codes... if it did, it was misfiring from dirty/worn spark plugs.

i GOPT p1070 CODE BUT I CLEARED THE CODE AND IT HASNT COME BACK AS YET AFTER 3 WEEKS. VAUXHALL SO DEFINATLY FUEL AIR RELATED.

Hello I Have This Issue To My Mitsubishi Colt 1.3 i P0170 Change The Fuel Pump,Fuel Pressure Regulator,Crank and Cam Sensor,O2 Sensor,MAP sensor,No Vaccum Leaks ( I Do Smoke Test,Change The Spark Plugs,i service My VVT Cam gear I Change Gasket Because It leaks Oil,I Change PCV Valve,Do Some Change Oil..

Play at 1.5x speed for a better experience

O2 sensor is lambda sonde?

I have this error on the same peugeot 407 2.2 gasoline engine. The engine doesn't rev more than 3500 rpm and have a tremendous loss of power(my combo 1.7 sdi with 60 hp has more power:)). Any idea what it can be?

Hi there I have opel corsa c1.2 2001 and I have the same code p0170 fuel trim bank. What should I change can You help me please thank you

Hi. Need help please!! First try to understand some words I use because I don't know the exact car terms. The car is opel corsa 2004 1.2 c. (Gasoline.) I had the same. When drive with middle gas pedal was good. But when go all of it the check engine light was on. Or when the light of fuel low was on, had it. I have the p0170 error. Plus a p0300 & p0302. Stared long a go. First change 4 sparks and for 2-3 days was ok maybe not because I was not stress the car after. The problem stays so I try to find out Then go to mechanic and looked the sparks again the multiplayer and "pipes" (hose) of sparks was ok. Then the injection system was ok too. Then change the fuel pump. The fuel in a gas station must not good so the pump the filter next to pump and the pump inside was full of small iron grains which sparkle in light. The gas filter out of tank was black and full of dirt.... put a new one Inside the pump was not work freely but working anyway. We check fuel hose from tank to engine there was dirt but clean them. Check the pump wires and clips again because problem stays After all these parts we checked - change .... the car is working much better but the light check engine is still there some times. Before go to mecanic I saw your video so know what to check. The mechanic says after he looked and the computer of car.. that the engine works in the borders (gets 24 % of gas but not understand him much) but he can't understand the other 2 errors p0300 which is multiple misfire engine And p0302 misfire on cylinder 2 after check the plugs, multiplier and injectors. Also change places of sparks multiplayers pipes, hose... Do you have any suggestions? Need more clues? We did not check air filter or maf or O2 sensor or anything involving with the air of the car. Thanks.

Even I am facing the same issue with my Renault pulse

I have P0170 on a peugeot 307 along with P0117
