What should the EGR be on my car?
What should the EGR be on my car?
Closed, the EGR volts should be about 0.8 and wide open we typically see 3.8 to 4.0 volts. Can any of you guys find out what a DTC code d262 is?
What happens when the EGR error is + 99%?
I could actually watch the mass air flow drop a rather large amount when the EGR error was +99%; unfortunately when the engine is regurgitating that much exhaust back into the exhaust; the exhaust out the tailpipe really stinks……
Why does my EGR light not come on?
Not sure a light would come on with these trucks; I know I can unplug the EGR valve, set 3 codes (p0403, p0405, p0406) and the light will not come on. Then, he told me it may be getting a lean signal, I told him it is a diesel. Then he indicated sometimes the the O2 sensor will read lean or rich; even on a diesel.
What’s the EGR value on my EBP sensor?
Last year when my EBP sensor was failing the scan tool would show EGR error of +99%; EGR command has never displayed anything but zero on my scan tool (because the scan tool incorrectly displays same!)
How can I check if my EGR valve is OK?
A quick way to check for this is to apply vacuum to the EGR valve and monitor engine operation. Assuming the EGR valve is ok the engine should begin to stumble and possibly even stall as vacuum is applied to the valve and the pintle opens. Your DPFE voltage should also approach 4.5 volts.

What should the EGR be on a diesel engine?
The accepted EGR static test is to measure the EGR position voltage at 0% (this is a KOEO test, BTW)and then command the valve to at least 99% duty cycle. Measure the EGR position voltage again. Closed, the EGR volts should be about 0.8 and wide open we typically see 3.8 to 4.0 volts.
What is the diagnostic code for engine stall?
Diagnostic trouble codes P0120, P0121, P0122, P0123, and P0124 are what will commonly appear. The engine can stall for no reason and without any warning. This happens when the TPS gives incorrect information to the ECM. The engine can stall at high speed, at low speed, or even at idle.
