How do you fix exhaust gas recirculation flow insufficient detected?
What repairs can fix the P0401 code?
- Replacing the leaking or clogged EGR valve.
- Replacing a broken vacuum line to the EGR valve or control solenoid.
- Replacing an EGR temperature sensor or clean the carbon off of it to repair it if it does not register enough of a temperature change.
What does error code P0401 mean?
Code P0401 Meaning This is likely due to faulty or clogged EGR valve or carbon buildup in the intake manifold or on the EGR temperature sensor.
Is it bad to drive a car with a bad EGR valve?
Technically speaking, you can drive your vehicle with a bad EGR valve without any major limitations. You might experience shaking at idle, rough running, popping sound, and that’s about it. Driving with a bad EGR valve will mean that your vehicle will produce a lot of toxic gasses for the environment.

Why does my Chevy Captiva have a p0401 code?
EGR Valve Itself is Bad – The EGR valve itself is usually not going to be the place to start. But, they certainly are the cause of P0401 often enough. Vacuum Issues – The EGR valve relies on engine vacuum to operate. So, if you are encountering P0401 and other codes, the P0401 may be a symptom of larger problems.
What causes a Mil p0401 to not work?
The only thing that i can find that would cause a MIL p0401 at this point is the sensor sending an incorrect reading of the EGR’s correct function, which should be a EGR temperature sensor (thermistor). But I cannot find any such sensor on the manifold, or in any repair diagrams.
