1992 F150 4.9 I-6


KOEO -332- Insufficent EGR flow detected (the EGR sensor has been replaced)

KOER-225- Knocked not sensing during dynamic response test



And why wont my dome light turn off? Ive taking the door button out and WD-40'd it and disconnected the button and the dome still stayed on,


thanks,

 

turn the headlight **** it should turn off then

 

Um, I would think that if your ECU is telling you that the EGR is not getting enough flow that the EGR would not be getting enough flow through it.. IE it's clogged and dirty. Try taking it off and scraping all the carbon out of it and hitting it with some carb cleaner. And the other code is the knock sensor not responding during the diagnosis test. Everywhere I've read it says it's operator error. Clear the code and it most likely wont come back, that is, after you clean your EGR.

 

He also said that the EGR has been replaced. So that leads toward a blockage where it bolts on or in a vacuum hose or the EGR position sensor is bad as it is what sends the EGR info to the computer.

 

He said he replaced the EGR sensor... not the EGR Valve

Also the dome light turning not off would lead one to believe that the wire coming from the door jamb switch is shorted to ground.

 

My Bad I misread OP. Red is right the EGR needs to be took off and cleaned or replaced.

 

I would lean more towards a bad vacuum line.
