Note On Intermittents

  1. Check for an intermittent short to ground on CKT 434.
  2. A stall or near stall condition which may set Codes P054 or P095 may cause Code P091 to set falsely. This is because the engine will transition from running to not running (or near stall) and then back to running without the transaxle range switch being in PARK or NEUTRAL.
