P0263 - Cylinder 1 Contribution/Balance

WARNING: This page is about a different car, the 2012 Ford Pickup, 2012 Ford F550 Super Duty, 2012 Ford F450 Super Duty, and 2012 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.
P0263 - CYLINDER 1 CONTRIBUTION/BALANCE

Description:  The powertrain control module (PCM) monitors the crankshaft speed and acceleration for each cylinder event. This DTC sets when the acceleration rate of the crankshaft is below or above 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.
