What is the diagnostic code for exhaust gas recirculation?
What is the diagnostic code for exhaust gas recirculation?
P0400 is a diagnostic trouble code (DTC) for “Exhaust Gas Recirculation Flow Malfunction”. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation. Our certified mobile mechanics can come to your home or office to perform the Check Engine Light diagnostic.
What does the OBD II fault code p0400 mean?
What Does Code P0400 Mean? OBD II fault code P0400 is defined as “ Exhaust Gas Recirculation Flow Malfunction”, and is set when the PCM (Powertrain Control Module) detects a problem with the amount of exhaust gas being rerouted to the inlet tract. Such a problem will cause a trouble code to be stored, and a warning light to be illuminated.
What does a code p0400 on an EGR mean?
A code P0400 may mean that one or more of the following has happened: Plugged EGR passage which restricts the flow of exhaust gasses Faulty EGR solenoid wiring/harness
Where does exhaust gas go in a p0400?
The gas is brought into the system from the No. 4 cylinder exhaust manifold. From there, it winds through the back of the cylinder head into the intake manifold and to the EGR valve. Then it goes back into the intake manifold and up an EGR transfer tube.
What is diagnostic code for exhaust gas recirculation?
Diagnostic trouble code P0400 is triggered when the flow of exhaust gas recirculation is lower than what the powertrain control module (PCM) expects. In modern vehicles, the EGR valve is controlled by the PCM.

What does the p0401 code mean on a car?
P0401 Code is relevant to your car’s EGR system. It lights up the Check Engine sign when the engine exhaust gas recirculation (EGR) valve isn’t pumping enough exhaust gases when it’s ordered to allow their flow into the intake manifold. What Causes My EGR to Malfunction?
