Are there any symptoms of a p0404 DTC?
There may be no symptoms of a P0404 DTC other than the MIL (malfunction indicator lamp) or check engine light. However, Exhaust Gas Recirculation systems are inherently problematic due to carbon buildup in the intake manifold, etc.
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.
How does the p0171 code work on a car?
The P0171 is one of the more common trouble codes. This code is triggered by the first downstream (front) O2 sensor. The sensor provides a reading of the air:fuel ratio leaving the engine’s cylinders, and the vehicles powertrain/engine control module (PCM/ECM) uses that reading and adjusts to keep the engine running at that optimum ratio of 14.7:1.
What causes a p0405 DTC in an EGR circuit?
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. 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

What causes a Dodge Caravan to fail an emissions test?
The Caravan’s ECM will trigger this code when it detects that the vacuum level in the Purge System is not within the proper specifications. P0441 can cause the vehicle to fail an emissions test. Often, the only symptom of P0441 will be the service engine soon light itself. In a few cases there may be other symptoms. Here they are:
