Engine codes P0404 & P1414 - what to do?
I am getting the following codes, just bought a scanner. What to do, can the EGR be cleaned instead of replaced?
P0404 Exhaust Gas Recirculation (EGR) Open Position Performance P1414 Says something like "Emissions Controller" |

P0404 Exhaust Gas Recirculation (EGR) P1414 Says something like "Emissions The EVAP system is trying to tell you something, not sure of that DTC 1414 though. You may have a vacum leak, or one of the valves in the evap sys are failing. Or gas cap is not holding vacum. Could be any number of things, but there's a few ideas. |
P 0404 = EGR System Performance
Will Set off a SES light P 1414 = None existant. Sure it's not a P 1404 or 1441? EGR Valve Closed or EVAP System Flow Durning Non-Purge? |
Forgot to mention, the car is stumbling out of the hole, especially cold. I am guessing the valve is stuck open and causing the poor performance?

Sounds like it's sticking shut actually....the EGR also helps to warm the intake air....To warm the motor up quicklky.
|
Thanks for all the info so far. So will the EGR cause this performance problem, the hesitation? What if I just unplug it? Any pros / cons to that?
|
If you just unplug it'll give you a light.
Attempt the cleaning and use a fresh gasket. Also try plugging and unplugging the connector about 5 times. |
Well ok, but what I mean is can unplugging it help with the hesitation and can it harm anything? I don't care if the check engine light is on for now....

OK - I unplugged it as I don't have time to clean it yet. The hesitation went away completely :)
What does this indicate? Is is safe for the engine and emissions system to leave it unplugged? will cleaning the EGR still be worthwhile? |
