P0014 medium Severity

P0014: B Camshaft Position – Timing Over-Advanced or System Performance (Bank 1)

Check Engine Light illumination, rough idle, potential reduced power and fuel economy

Overview

OBD-II code P0014 indicates the bank 1 exhaust camshaft timing is more advanced than expected, often related to variable valve timing (VVT) system faults, oil issues, or mechanical timing errors

Common Symptoms

  • Check Engine Light illuminated
  • rough idling
  • hard starting
  • reduced fuel economy
  • engine hesitation or stalling

Most Common Causes

low or dirty engine oil affecting VVT control high

Oil contamination or low level can restrict oil flow to camshaft phasers and VVT solenoids, leading to over-advanced cam timing.

faulty variable valve timing (VVT) solenoid / oil control valve high

VVT solenoid sticking or electrical failure can cause incorrect oil routing to cam phasers.

camshaft phaser malfunction or sticking medium

Mechanical wear or internal failure of the cam phaser can cause incorrect cam timing.

timing chain/belt stretch or misalignment medium

Improper mechanical timing due to chain/belt issues can mimic VVT timing errors.

faulty camshaft or crankshaft position sensor signals low

Sensor misreads can falsely indicate timing is over-advanced; less common than oil/VVT issues.

Diagnostic Steps

  1. Scan for codes and view freeze frame data with OBD-II scanner
    Expected: P0014 present with potential accompanying codes (e.g., P0011, P0024)
    Interpretation: Confirms timing over-advance event and context
  2. Check engine oil level, quality, and viscosity
    Expected: Oil at correct level and clean
    Interpretation: Dirty or low oil often contributes to VVT timing issues
  3. Inspect and test VVT solenoid and oil control valve for operation and electrical continuity
    Expected: Proper actuator movement and correct resistance values
    Interpretation: Faulty or clogged solenoid indicates replace or clean
  4. Inspect camshaft and crankshaft position sensors and wiring
    Expected: No broken wires, correct voltage signals
    Interpretation: Exclude sensor misreads
  5. Perform mechanical timing inspection (timing chain/belt and cam phaser)
    Expected: Proper alignment and tension
    Interpretation: Mechanical timing issues require repair

Repair Solutions

Engine oil and filter change with correct viscosity oil easy
Estimated Cost: $40 - $120

Often resolves oil-related VVT issues if oil quality is poor

Replace VVT solenoid / oil control valve medium
Estimated Cost: $150 - $400

Common repair when solenoid is clogged or fails

Repair or replace timing chain/belt and associated components hard
Estimated Cost: $600 - $1900

Required for mechanical timing faults

Replace camshaft phaser hard
Estimated Cost: $500 - $1500

Necessary when mechanical phaser failure is confirmed

Common Misdiagnoses

Avoid these common diagnostic mistakes:

  • Incorrect diagnosis of intake camshaft fault (P0011) instead of exhaust camshaft P0014
  • Faulty camshaft sensor instead of actual VVT oil control problem

Frequently Asked Questions

Can you explain the meaning of P0014?

Technically, the P0014 code represents B Camshaft Position – Timing Over-Advanced or System Performance (Bank 1). It usually points to a fault within the Engine Mechanical.

Is it safe to drive with a P0014 code?

You should treat P0014 as a medium issue. Check Engine Light illumination, rough idle, potential reduced power and fuel economy

What happens when the P0014 code is active?

Common symptoms include: Check Engine Light illuminated, rough idling, hard starting. You might also notice the Check Engine Light is on.

Why is my car throwing a P0014 code?

Potential culprits include: low or dirty engine oil affecting VVT control, faulty variable valve timing (VVT) solenoid / oil control valve, camshaft phaser malfunction or sticking. A proper diagnosis is recommended.

How much does it cost to fix P0014?

Expect to pay around $120 if the issue is a Engine oil and filter change with correct viscosity oil, but up to $1900 if the Repair or replace timing chain/belt and associated components needs replacement.

Is P0014 a generic or manufacturer-specific code?

P0014 is not specific to any one brand. It can appear on Ford, Dodge, Toyota, Honda, Jeep, and other vehicles.
