P0405

Description
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.

Symptoms
You likely won't notice any drivability problems.

Causes
  • EGR feedback is less than .14 volt at anytime.

Possible Solutions
  • Check for poor terminal connections at EGR valve.
  • Check for excessive deposits on EGR valve pintle or seat.
  • Replace EGR
