Symptom: P0405 - EGR POSITION SENSOR LOW When Monitored and Set Condition: P0405 - EGR POSITION SENSOR LOW When Monitored: With the ignition on. Battery voltage above 10.0 volts. Set Condition: EGR Position Sensor Signal is less than 0.1026 of a volt. One trip Fault. POSSIBLE CAUSES EGR POSITION SENSOR SWEEP INTERMITTENT CONDITION 5 VOLT SUPPLY CIRCUIT SHORTED TO GROUND 5 VOLT SUPPLY CIRCUIT OPEN EGR POSITION INTERNAL FAILURE EGR POSITION SENSOR SIGNAL CIRCUIT SHORTED TO GROUND EGR POSITION SENSOR SIGNAL CIRCUIT SHORTED TO SENSOR GROUND CIRCUIT PCM 5 VOLT SUPPLY CIRCUIT PCM EGR POSITION SENSOR SIGNAL TEST ACTION APPLICABILITY 1 Turn the ignition on. t, read the EGR Position Sensor voltage. Is the voltage below 0.2 of a volt? All Yes → Go To 2 No → Go To 10 2 Turn the ignition off. All Yes → Go To 3 No → Go To 7 3 Turn the ignition off. t, monitor the EGR Position Sensor voltage. Turn the ignition on. All Yes → Replace the EGR Solenoid Assembly. Perform POWERTRAIN VERIFICATION TEST VER - 5. No → Go To 4 153 DRIVEABILITY - NGC |
