DRIVEABILITY - GAS
Symptom:
P0406 - EGR POSITION SENSOR VOLTS TOO HIGH
When Monitored and Set Condition:
P0406 - EGR POSITION SENSOR VOLTS TOO HIGH (2.7L)
When Monitored: With the ignition on. Battery voltage greater than 10 volts.
Set Condition: EGR position sensor signal is greater than 4.9 volts 6 seconds.
EGR POSITION SENSOR SWEEP
INTERMITTENT CONDITION
(K235) EGR POSITION SENSOR SIGNAL CIRCUIT SHORTED TO (K6) 5-VOLT SUPPLY CIRCUIT
(K235) EGR POSITION SENSOR SIGNAL CIRCUIT SHORTED TO BATTERY VOLTAGE
EGR SOLENOID ASSEMBLY INTERNAL FAILURE
(K235) EGR POSITION SENSOR SIGNAL CIRCUIT OPEN
(K4) SENSOR GROUND CIRCUIT OPEN
PCM
TEST
1 When monitoring EGR valve position on the DRBIII during actuation, a
delay in valve movement will occur until enough duty cycle is applied to
overcome the spring force in the EGR valve, this is to be considered normal
operation.
Start the engine.
With the DRBIII , read the EGR Position Sensor voltage.
Is the voltage above 4.5 volts?
Yes → Go To 2
→ Go To 8
No
2 Turn the ignition off.
Disconnect the EGR Solenoid harness connector.
Disconnect the PCM harness connector.
Measure the resistance between the (K235) EGR Position Sensor Signal circuit and
the (K6) 5-volt Supply circuit in the EGR Solenoid harness connector.
Is the resistance below 100 ohms?
Yes → Repair the short between the (K6) 5-volt Supply and the (K235)
→ Go To 3
No
