P20A0: Understanding Your Car’s Fuel System Fault
The P20A0 fault code relates to the reductant purge control valve circuit. To reverse the reductant flow direction, a 4-2-way valve needs to be switched by a solenoid.
The reverting valve functional check monitors the pressure drop during the purge cycle. For a successful test result, the pressure must drop by a threshold of 230 kPa within a specific time.
If the test is not passed, the purge cycle will be terminated immediately to avoid uncontrolled injection of reductant into the exhaust pipe.
