P0014 – Meaning, Causes, Symptoms, & Fixes

Code P0014 Definition

Camshaft Position “B” – Timing Over -Advanced or System Performance (Bank 1)

What Does P0014 Mean?

Variable Valve/Camshaft Timing in the internal combustion engine control the intake and exhaust gases in and out of the gas combustion chamber. You want to vary the way your engine operates at different points of the engine’s rev range. Varying the different valve events: valve timing, valve duration, and valve lift allows the ECU to constantly make a call to the most power, the best mpg, and the lowest emissions. The different pistons that pump up and down leave the exhaust valves with the maximum air space that the engine can take in fuel and air to give you maximum power. When trouble code P0014 is set, it means that camshaft position “B” in Bank 1 is more advanced than the ECM has told it to be.

P0014 Symptoms

  • Check Engine Light
  • Hard start of the engine
  • Rough running engine
  • Decreased fuel economy
  • Failed emissions test

P0014 Causes

  • The exhaust shaft has advanced too much when the ECM has told it to slow down to a lower timing level.
  • Camshaft variable timing solenoid failure
  • Camshaft phaser is seized in the advanced position
  • Continuous oil flow to Variable Camshaft Timing chamber

Code P0014 Severity – Moderate   

The engine may have erratic and other engine problems that could affect driving and fuel economy may decrease due to increase fuel consumption. As for any Diagnostic Trouble Code it should be repaired as soon as possible for no internal damage.

Code P0014 Common Diagnosis Mistakes

Replacing sensors or components without any indication of a problem with the sensors or components.

P0014 Diagnosis

  • Tools Needed to Diagnose:
    • FIXD
    • Vehicle specific service manual

Difficulty of Diagnosis and Repair – (1-4)

  1. Visually inspect the connector, wiring, or valve problems with the Oil Control Valve for bank 1 exhaust valve.
  2. Check the engine’s oil level and viscosity to see if they are correct.
  3. Check the live freeze frame data
    1. Monitor the timing of the data and disconnect the Oil Control Valve to the exhaust camshaft. If there is a change it means that the valve is working correctly and there is an electrical problem within the ECM.
  4. Find your vehicle specific service manual and follow the pinpoint tests to repair them as needed.
