What causes engine to stall with code p0405?
The EGR position is critical for the ECM to properly control the EGR valve opening and closing, and can cause the engine to run rough and stall. What repairs can fix the P0405 code? Code P0405 is triggered when the EGR position is below the ECM expected sensor position and the most common cause is the EGR sensor has an open circuit internally.
What should I know about the p0404 code?
CAME UP EGR SYSTEM FAILED FAILED EGR POSITION SENSOR OPEN OR SHORT CIRCUIT CONDITION FAILED EGR VALVE FAILED EGR POSITION SENSOR APPLICABLE OK SO THIS IS WHAT CAME UP WHEN THEY READ THE CHECK ENGINE LIGHT SOOOO I HAVE CHANGED THE EGR VALVE AND STILL WONT GOT PASS 10MPH AND JUST STUMBLES ALL OVER ITS… Need more help with a p0404 code?
What are the symptoms of a p0405 DTC?
Symptoms of a P0405 DTC may include: Potential causes of a P0405 code include: Short to ground in EGR signal or Reference circuits Short to voltage in EGR ground or signal circuits Bad PCM wiring issues due to chafing or loose terminals If you have access to a scan tool you can command the EGR valve on.
Why is the p0405 EGR sensor a circuit low?
There should also be an electrical connector on this type of EGR valve for the feedback circuit. The EGR system feedback circuit allows the PCM to see if the EGR valve pintle is actually moving as it should. If the feedback circuit detects that the voltage is unusually low, or it’s position is lower than it’s commanded to be, P0405 may set.
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.

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.
