Nissan Repair Questions? Ask a Mechanic for Answers ASAP
Hello my name is ***** ***** thank you for your question
What codes do you have?
Did you check to see if the tube that has the EGR temp sensor is clogged up with carbon?
If the solenoid is staying energized, that is powered by the Ecm. Did you replace the Ecm?
Has the intake been checked for carbon build up as well where the EGR Pipe bolts into it? Are you doing the work or a repair shop?
If you lift the EGR diaphram with the engine at idle, will it stall the car?
I understand that. But I am trying to think of why the computer is doing this. It's still looking for some kind of signal which is why it is keeping the solenoid open so long.
The only thing I can think of to try to isolate what signal is causing the Ecm to keep the EGRC solenoid open so long is to do a Ecm Terminal Reference check. There has to be a signal out of spec.
Are you a repair shop?
I already understand that. I am inquiring if you are doing the work? If you are, I can share the Ecm terminal reference check to see if there is something out of spec causing the Ecm to keep the solenoid on longer than it should
That is the complete Ecm terminal reference check. For your issue, each pin will need to be checked and it's readings compared to the specs provided
Are you on a computer or a cell phone?
Ok. You got it. It is in a PDF format.
