EGR PINTLE POSITION SENSOR CIRCUIT LOW VOLTAGE
PCM monitors EGR valve pintle position input to ensure that
valve responds properly to commands from PCM and to detect a fault if
pintle position sensor circuit is open or shorted. If PCM detects an
excessively low EGR feedback signal voltage, DTC will set.
You likely won't notice any drivability problems.
- EGR feedback is less than .14 volt at anytime.
- Check for poor terminal connections at EGR valve.
- Check for excessive deposits on EGR valve pintle or seat.
- Replace EGR
