P0404 - EGR POSITION SENSOR RATIONALITY —
TEST
3 Turn the ignition on.
Perform a Voltage Drop Test on the (K6) 5-volt Supply circuit between the EGR
Solenoid harness connector and the PCM harness connector.
Is the voltage drop more than 0.3 volts?
Yes → Repair the resistance in the (K6) 5-volt Supply circuit.
No
4 Turn the ignition on.
While backprobing the PCM harness connector, measure the voltage of the (K6)
5-volt Supply circuit.
Is the voltage above 4.8 volts?
Yes → Go To 5
No
5 Turn the ignition off.
Disconnect the EGR Solenoid harness connector.
Disconnect the PCM harness connector.
Measure the resistance of the (K235) EGR Sensor Signal circuit between the EGR
Solenoid harness connector and the PCM harness connector.
Is the resistance below 5.0 ohms?
Yes → Replace the EGR Assembly.
No
6 Turn the ignition on.
With the DRBIII , actuate the EGR Solenoid.
Allow the EGR Solenoid to actuate for least 15 seconds.
Feel the EGR solenoid for operation.
Stop actuation.
Does EGR Solenoid operate during actuation test and than turn off when actuation
test was stop?
Yes → Refer to the INTERMITTENT CONDITION symptom in the
No
7 Turn the ignition off.
Disconnect the EGR Solenoid harness connector.
Turn the ignition on.
Measure the voltage of the (K235) EGR Sensor Signal circuit at the EGR Solenoid
harness connector.
Is the voltage above 4.30 volts?
Yes → Go To 8
No
