In this video I have a look at a customers 2001 Chevy 2500HD with the big 6-oh and the customer states it runs very poorly as soon as it warms up. A little bit of time looking at some running data we soon discover a huge problem in the fuel trims and notice the O2 sensors are not working like they should. Sounds easy enough right?

Had a 6.0 2500 GMC truck where the engine would run fine in open loop but when it went to closed loop would lean out all bank 2 cylinders. What was happening was the ac drain was dripping water onto the B2 S1 sensor connector, shorting the 12v heater ckt to the sensor signal circuit, creating a false rich exhaust condition. The ECM would try to lean it out by reducing injector pulse width to the point all 4 cylinders would misfire.

I’ve worked on MRI systems for 39 years. Analog to Digital circuits are genuinely complex. The A/D converter doesn’t care that much about current. (Caveat: it does, but only to develop a voltage). Nano-amps of current when run through an RF filter and fed to an A/D converter will happily work just fine, and provide a digital representation of the voltage it senses. The same goes for a modern day DC digital voltmeter. So just the salt deposit on both insulators acted as a very high input impedance short, and some tiny value of current flow was established. Maybe in the nano-amp range. The ECM A/D converter happily did the conversion and sent it to the digital computer side of the ECM and BOOM, the O2 sensor had an offset. In other words, you nailed it, Mr. O! Perfect description and understanding of parasitic current flow on the outside of an insulator. Nicely done, and outstanding troubleshooting. And if you prick a wire, always seal it up with liquid electrical tape! Thanks, Mr. O!!

Understanding the sensitivity of the miliamp/volt circuitry can really help zero in on diagnostics. Knowing your influencial environment like salt corrosion whether from winter road maintenance or ocean is huge in terms of where to look for potential trouble spots. Here in Hawaii, electrical connections full of corrosion go unnoticed because there isn't a bunch of green puss around the connection, but that light oily salt film is actually everywhere. I would imagine even there in New York or any seaboard location. I live at 4,600ft elevation, but here in the middle of the Pacific ocean, there is nowhere that you don't have salt air. Excellent catch Eric, perhaps you have worked in a salty environment before.😂 It amazes me how such a slight oily film can affect the sensitivity of electronics.🤙

Got to love that salt's conductivity. I once had a customer with a 54' Bertram powered by12V92TA Detroits call me one morning that said one of his engines just started up by itself at the marina in the middle of the night. Went and checked it out, and a pinhole had developed in the a/c condenser water manifold (uses raw water for cooling) that was outboard the port engine. A fine stream of salt water had misted the starter solenoid and lit the engine off. Had to rebuild the starter. Definitely strange, but not hard to find why.

Amazing troubleshooting, Mr. O. Gotta admit, this well seasoned electronics technician is impressed with your skill and determination. I've seen high voltage (several thousand volts) find some odd pathways across non-conductors but never anything with voltages this low. With HV, there's always the possibility of carbon tracks created as a result of arcing across contaminated insulators creating a high resistance pathway from point a to point b. How (presumably) vinyl insulation can become conductive like this is new to me. Bravo!

I think you nailed it. The salt itself is conducting, and is more than happy to reach the conductors thru any pinhole or other means available. Super bad environment up there in PRNY. If a good O2 sensor has a comparatively low impedance to the input of the ECM, having it unplugged (or a bad connection to it) would leave only the path thru the contaminants to determine the voltage - whereas when the O2 sensor is in the circuit, it would mainly be the determining factor. But what do I know? I'm a plumbah, for cryin' out loud!

Dry finger to finger resistance is 1000 to tens of thousands of ohms. I looked that up out of curiosity when I saw the finger touch test result. So if I understood, the circuit is: heater power wire (voltage source) to pin hole to road grime to dry fingers to road grime on the sensor wire to pinhole on the sensor wire to the computer's sensor input. When the O2 sensor is plugged in you wind up with some sort of voltage divider that is splitting the heater voltage and the O2 sensor voltage, and that messed up result is then read by computer. And to exacerbate that, the pin hole branch of the circuit drops in resistance when it's wet. Spraying water on it might have showed a change on the O2 voltage reported on scanner. Very interesting indeed.

A good addition to your business if space permits would be a drive over underbody wash. You could make money like a car wash and money in the time it saves you working on cars that aren't so rotted out.

Great bit of electrical diagnosis. I learnt a lot about the high impedance nature of the Oxygen sensor signal wire! Eric your understanding of electrical circuits is truly impressive!

Physically I've been out of the business for a decade mentally not so much. I have to say you really are amazing. I have put a word into a small extended warranty company that if you ever call just pay what ever you say needs to be done. ( pretty sure you won't as it on the other side of the U.S. but yea ). Thanks for taking us along only wonder what your start to real end time is on the diagnosis... Merry Christmas to you, your family, friends, and anyone who reads this weither it be today, tomorrow, next week or next year as there will always be another one.

Mr O, you are a gem of a person and you just saved me a whole lot of trouble fixing this exact problem on my Chebby plow truck. I'll learn proper diagnostics by spring, but this got me up n running for snow season. God bless you and merry Christmas to the family!
