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…
What does the DTC code p0404 stand for?
Diagnostic Trouble Code (DTC) P0404 stands for Exhaust Gas Recirculation Circuit Range/Performance Problem. It is a generic OBD trouble code that activates if the powertrain control module (PCM) detects erratic Exhaust Gas Recirculation (EGR) valve performance. Code P0404 activates when the car computer detects erratic EGR valve performance.
What does p0404 mean on an EGR valve?
Code P0404 usually indicates that there is a carbon build-up somewhere in the lines, or on other occasions, a bad EGR valve. Increased nitrogen oxide emission may indicate a failing EGR valve.

P0404 Code: Exhaust Gas Recirculation Circuit Range/Performance Problem – In The Garage with CarParts.com Chrysler EGR Scope Diagnostics, P0404
Diagnostic Trouble Code (DTC) P0404 stands for Exhaust Gas Recirculation Circuit Range/Performance Problem. It is a generic OBD trouble code that activates if the powertrain control module (PCM) detects erratic Exhaust Gas Recirculation (EGR) valve performance. Code P0404 activates when the car computer detects erratic EGR valve performance.
Why is my p0404 exhaust gas recirculation not working?
The actual EGR position should be very close to the “desired” EGR position. If it is, then the problem is likely intermittent. It may have been a lodged piece of carbon that has since dislodged, or it could be a bad EGR valve winding that intermittently opens or shorts as the valve temperature changes.
What kind of EGR valve does a p0404 have?
If you have a P0404, then the EGR valve is likely an electrically controlled EGR valve instead of a vacuum controlled EGR valve. Also, the valve will usually have a feedback system built into it that informs the PCM (Powertrain Control Module) what position the valve is in; open, closed, or somewhere in between.

What does the OBD fault code p0404 mean?
We recommend Torque Pro. P0404 is a generic OBD II fault code that indicates that there is an issue with the Exhaust Gas Recirculation (EGR) circuit. The Engine Control Module (ECM) has detected that the EGR circuit is either out of range or not functioning properly.
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 OBD code for exhaust gas recirculation?
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.
