What does DTC p0403 mean on an EGR solenoid?
The EGR solenoid is actuated with a 12-volt power source, switching the solenoid from the “leaking” position to a closed position when power is present. DTC P0403 most commonly indicates an electrical issue with the solenoid or the electrical connections.
What is the OBD code for the EGR?
There are several OBD-II codes related to a faulty component in the EGR that may appear on your OBD scanner. One of them is the P0403 code. The code P0403 activates when the PCM detects that the desired and actual states of the EGR control circuit do not match during operation.
What are the symptoms of EGR solenoid malfunction?
Symptoms vary depending on the position of the EGR solenoid circuit during malfunction. Symptoms may include: Check Engine light. Rough run or misfire on startup, smoothing out as engine warms up. Rough run or misfire when engine hot, yet runs properly on startup. Hesitation to accelerate.
What are the letters on an EGR valve?
Most of the EGR valves will have the letters A thru’ E molded onto the EGR valve’s connector. I’ll be using these same letters for the circuit descriptions below: Ground circuit for EGR valve solenoid. Gray with Black stripe wire. EGR valve pintle position sensor Ground (provided by the PCM). Black wire. EGR pintle position signal circuit.
