SYMPTOM
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.

POSSIBLE CAUSES
- EGR position sensor sweep

- (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
- (K35) EGR position sensor signal circuit open
- (K4) sensor ground circuit open
- PCM
