2013 Ford Explorer Police Interceptor, AWDSECTION DTC P0012: Intake Camshaft Position Timing: Over-Retarded (Bank 1)
DTC P0012: INTAKE CAMSHAFT POSITION TIMING: OVER-RETARDED (BANK 1)

Description:  The PCM monitors the variable camshaft timing (VCT) position for over-retarded camshaft timing. The test fails when the camshaft timing exceeds a maximum calibrated value or remains in a retarded position.
Possible Causes: 
  • Camshaft timing incorrectly set
  • Continuous oil flow to the VCT piston chamber
  • Erratic camshaft position due to low oil pressure
  • Oil flow restriction in the oil passages or the VCT valve body
  • VCT solenoid valve stuck open
  • VCT circuit open
  • VCT circuit short to voltage
  • VCT circuit short to ground
  • VPWR circuit open
  • Camshaft advance mechanism binding (VCT unit)
  • Damaged VCT phaser
  • Damaged camshaft position (CMP) sensor
  • CMP sensor circuits open
  • CMP sensor circuits short to voltage
  • CMP sensor circuits short to ground
  • Radio frequency interference
Diagnostic Aids:  These DTCs may be accompanied by other DTCs. Diagnose all CMP sensor DTCs first. If no CMP sensor related DTCs are present, continue to follow diagnosis for this DTC. This DTC is a functional check of the VCT unit. Diagnose any base engine concerns related to the engine oil pressure or engine timing. Refer to the appropriate Engine System article, Oil Pressure Test, to check the engine oil pressure. REFER to the appropriate Engine article, Timing Drive Components, to check the engine timing and VCT phasers.

When to See a Mechanic

Stop DIY work and contact a certified mechanic immediately if any of the following apply:

  • • You smell fuel, burning insulation, or see smoke.
  • • Brakes feel soft, pull hard to one side, or make grinding noises.
  • • The engine overheats, stalls repeatedly, or misfires under load.
  • • You are missing required tools, torque specs, or safe lifting equipment.
  • • You are not confident in the next step or safety outcome.
