What does service traction control mean


I had this alarm on my 2008 Equinox. I did not have it code scanned, but I found on the internet that a code P0403 or P0405 could suggest a faulty EGR .
I took a chance and replaced it for about $80 bucks and 30 mins. time and it corrected my problem so far.
I think Autozone will run a code scan on your SUV for free and they might suggest something else.

OBD-11 codes 0403 & 0405


code p0403 refers to EGR --circuit malfunction===causes ---wiring--EGR solenoid---ECM
code p0405 refers to EGR valve position sensor A --low input===causes ---wiring ---short to ground---EGRF valve position sensor--- ECM.
By only changing the EGR valve you have not fixed the problems that cause the valve not to work.

I have a 2000 buick regal LS with the 3800 series II engine. My service engine soon light came on and it was coded with a bad egr valve. The car was jerking whenever i went up a hill or tried to pass...


What code ? are a few different ones for EGR valve > Low & high circuit voltage , testing circuits , PCM testing etc.... no code tells you to replace the EGR valve without testing . Your best bet , take it to a qualified repair shop.

DTC P0404 Exhaust Gas Recirculation (EGR) Open Position Performance
