California smog requires that the EGR system recirculates exhaust at around mid throttle. If its not opening the smog scanner machine fails the car.
I bought this car non-running thinking it had a blown head gasket and that I could fix and flip it.
Turns out the head was trash with two burnt valves.
Another 450.00 for head+ 80.00 on gasket set+ 95.00 to overhaul the four injectors. Now 68.00 for a failed smog, I'm in upto my neck for what the car is booked at.
When I first got it running after the head build, I had a hard check engine light. I pulled the code and the only one there was a code 32 for EGR temp sensor.
I pulled the sensor and it was carboned and sooty black. I cleaned it up with a brush and brake clean and the light went away. Thats when I ran it over to the smog shop to try and get a smog certificate, it failed. How can I bench test the EGR temp sensor?
Do I heat it with a flame or will boiling water work?
Am I looking for ohms Between the two pins or straight continuity?
I may me in over my head with this endevor trying to diag tech stuff using stone knives and bearskins, but I will probably have to keep this one.
