Jeep Grand Cherokee: Loud Exhaust, Engine Light & Leaking Brake Line If the early O2 sensors at least on GM's would get oil or some kind of junk on the outside of the sensor, they wouldn't work correctly because it sampled outside air along with the exhaust. I never had no luck cleaning them because what you used to clean them would further pollute the sensor. Hopefully you can get the old girl up and running. Good video

Eric O. you point out several things that I miss in your explorer examinations. I have to admit that I jumped ahead in this video looking for the carnage repairs. I guess I'm sick when need that PRNY rust repair video to get my day going. I'll be waiting with my coffee for part II. Thanks for all your hard work that your viewers enjoy.

A lot of dodges use engine temp to control o2 heater circuit. I had a 2008 grand caravan 3. 8 that guy replaced 3 o2 sensor himself. kept burning heater circuit up, i found his thermostat wasn't opening fully or at proper time. causing it to run the sensor too long burning up the elements in the o2 sensor.

O2 sensors need access to atmospheric oxygen, usually through a small vent next to the wire. If it gets blocked with oil or other crud, the sensor will be unreliable. A quick squirt with brake cleaner and careful poke with a probe sometimes brings them back to life.

Bad grounds was a problem in the 60's with dads all welded construction. yes in rust belt even welds become resistive. ground wire added block to chassis to body fived most problems

18 tacoma 2 wheel drive, replace cylinder head and have to put together new cylinder head. Customer pay what would you charge hours wise and how long would it take you roughly

Remarkable that it’s not eat up with rust. You think that silly announcement is going to deter us from watching the best mechanic in the whole north east. Hahahaha good try.

When I watch your videos I feel like I’m taking an automotive class at my local Vo-Tech School. Thanks for sharing your knowledge and expertise!

I think it monitors it by how long it takes it to start switching, if its slow to respond, the PCM determines that the heater has failed.

Of course somebody can do it cheaper when they do a half butt job. half the job is half the money but the repair doesn't last.

they should have sprayed that car with oil a bit of rust on it the oil leaks might help keep it from rusting away as fast LOL
