What happens EGR sensor valve is bad?
What happens EGR sensor valve is bad?
A faulty EGR valve can cause problems with the flow and operation of the EGR system leading to performance issues including a reduction in power, reduced acceleration and decreased fuel efficiency. EGR valves can become stuck ‘open’ or ‘closed’ due to a build-up of soot particles, carbon deposits and dirt from fuel.
What does the OBD code p0404 mean?
What the P0404 code means. P0404 is an OBD-II generic code that the engine control module (ECM) detected the engine exhaust gas recirculation (EGR) valve or sensor is out of specification range or its performance has gone out of specification parameters.
Can a p0404 engine have too much EGR?
(Too much EGR and the engine won’t idle). If you have a P0404, then the EGR valve is likely an electrically controlled EGR valve instead of a vacuum controlled EGR valve.
What is the p0404 exhaust gas recirculation circuit range?
Hello, I have a 1998 Sonoma SLS 4.3 auto, 4×4 with 150,000kms, I have been recently been having issues with the truck surging, revving up & down slightly & is very sluggish. I put it on a 3130 scanner & the code that came up was P0404 Exhaust Gas Recirculation Control Circuit Range Per…
Is the p0404 valve on my Malibu gone?
I have a 2002 Chevy Malibu LS with the 3.1L V6 engine. I had a p0404 code and when I did my tune-up recently, I went ahead and replaced the EGR valve. However, after two days of normal driving (approx. 70mi each day), the code has not gone away.
