DTC P0263: CYLINDER 1 CONTRIBUTION/BALANCE

Description:  The PCM monitors the crankshaft speed and acceleration for each cylinder event. This DTC sets when the acceleration rate of the crankshaft is greater than or less than the calibrated value.
Possible Causes: 
  • Base engine concerns
  • Damaged valve train assembly
  • Damaged fuel injector
Diagnostic Aids:  Carry out the power balance test to verify cylinders contribution. Disregard any DTCs set as a result of the power balance test. Single or inconsistent non-contributing power cylinder traces may be caused by a natural variation in a crankshaft speed and should be ignored.
