Diagnostic Aids: Notes

The following conditions may cause this DTC to set:

• The crankshaft reluctor wheel is damaged or improperly installed.
• The sensor is coming in contact with the reluctor wheel.
• If the crankshaft rotates backwards, this DTC sets. This condition is only with vehicles equipped with a manual transmission. This condition can occur when a vehicle is on an incline and the clutch is released and an engine stall occurs.

Excess crankshaft end play will cause the CKP sensor reluctor wheel to move out of alignment with the CKP sensor. This could result in any of the following conditions:

• A no start
• A start and stall
• Erratic performance

An improperly installed crankshaft could cause excess crankshaft end play.

If the condition is intermittent, refer to Intermittent Conditions .

Ignition system DTCs set with the ignition in the Start position if the starter relay or the starter is inoperative. When the PCM enables starter operation, the PCM also initiates the diagnostic test routines for DTCs P0335, P0340, and P0385. If a condition exists which prevents the engine from cranking, the PCM will not receive signal input from the CKP and CMP sensors, and the DTCs will set.

If DTC P0615 is set, diagnose DTC P0615 first. If DTC P0335, P0340, and/or P0385 are set and no condition is found, inspect for the following conditions:

• Is there a no-crank condition or an intermittent no-crank condition?
• Was an attempt made to crank the engine with the shift lever not in Park or Neutral?
