P0015 Code: Meaning, Symptoms, Causes (& Repair Cost 2022)

The P0015 trouble code indicates that the car’s powertrain control module (PCM) has detected a difference in the actual camshaft position angle and the required camshaft position angle. This trouble code is not much serious code. This article mainly explains the P0015 code meaning, symptoms, and causes.

P0015 Code Definition

The P0015 code stands for Exhaust Camshaft Position “B” – Timing Over-Retarded (Bank 1).

What does the P0015 Code Mean?

The P0015 code indicates that the powertrain control module (PCM) has detected that the exhaust camshaft timing for bank 1 is more retarded than what the PCM has commanded it to be. The over-retarded timing condition can be during the advancing or retarding phase.

P0015 code

This code is related to the engine’s variable valve timing system. A variable valve timing solenoid is also known as an oil control valve (OCV). This system improves engine performance and fuel economy by adjusting the closing and opening timing of the exhaust valve and intake valve.

The P0015 code will be triggered when the PCM detects that your vehicle’s camshaft timing is over-retarded.

Causes of the P0015 Code

Following are the major causes that trigger the P0015 code:

  1. Bank 1 camshaft oil control solenoid valve may be stuck in the open position.
  2. The oil control valve has an open circuit, or the PCM has an open circuit.
  3. A bad camshaft position sensor
  4. Bad VVT actuator (phaser)
  5. Incorrect oil viscosity
  6. Insufficient or dirty engine oil
  7. The oil viscosity is too high and is blocking the passages, restricting oil flow to or from the camshaft phaser.
  8. Bad or damaged Variable Camshaft Timing Solenoid Valve
  9. Worn timing belt or timing chain
  10. An issue with the PCM

Symptoms of the P0015 Code

  1. Illuminated check engine light
  2. Your engine may face hard start issues and low power conditions due to the retarded timing position.
  3. Failed emission test
  4. Engine misfiring
  5. Poor engine performance
  6. Knocking/Rattling from engine
  7. Engine stalling
  8. Poor fuel economy

Common P0015 Code Diagnosis Mistakes

It is essential to avoid these mistakes when diagnosing or fixing error code P0015:

  1. Not properly interpreting the freeze frame data in relation to when the code was set.
  2. Verify the failure and codes before attempting any repairs.
  3. Inspect the connectors and wiring harnesses to confirm they are not corroded.
  4. Visually inspect for an issue with the connections or wiring to the components.
  5. Make sure the engine oil is full, clean, and of sufficient viscosity.
  6. Replace parts only as directed by the pinpoint test or after a visual check indicates a problem.
  7. Obtain the service manual for your definite car and follow the manufacturer’s testing steps to diagnose or repair your car efficiently.

How to diagnose the P0015 Code?

You must have the following tools to diagnose or fix the P0015 code:

  • Fused jumper wires
  • Basic hand tools
  • OBDII scan tool
  • Specific car service manual

Follow the below-given steps to diagnose the P0015 code:

  1. Run a scan check, check for other codes with P0015, and clear the engine warning light with a scan tool.
  2. Ensure the connections and wiring between the OCV and your printer are in good working order.
  3. Use a dipstick to inspect the level and condition of the engine oil. If your car has insufficient oil, add more oil and road-test the car to confirm the problem has been corrected.
  4. Loosen hood screws and check the engine for deposits. If it contains sludge, the oil passages are clogged with debris, and the engine needs to be disassembled and flushed.
  5. Inspect the oil filter and replace it if needed.
  6. Scan and document engine codes and view the freeze frame data to see when the code was set.
  7. Reset the Check Engine Light and road test again to see if the code returns.
  8. Command the OCV on and off with the scan tool to see if the camshaft timing changes
  9. Perform the manufacturer’s tests for the P0015 code.

Note: You must follow the recommended pinpoint tests of the manufacturer to narrow down the issue because each engine may be tested differently.

P0015 Code Repair Cost

To fix or repair the P0015 code, you may need one or more of the following repairs. These prices are based on national averages and include parts and labor. Your cost may vary according to your area, vehicle model, and labor cost. 

Engine$2900 to $4100
OCV replacement$320 to $410
Oil Change$50 to $70

FAQ Section

How serious is the P0015 code?

A P0015 code does not mean that the vehicle will break down or stop running. However, it does affect your engine’s power and fuel economy. This code increases fuel consumption and can lead to carbon deposits on pistons and engine valves.

If you drive the car with the camshafts retarded for a long time, additional internal engine issues may develop, beginning with stalling and rough running.

What repairs can fix the P0015 code?

  • Reset the fault codes and perform a road test
  • Replace the camshaft-phasers on both camshaft banks
  • Repair the wiring or connections to the camshaft OCV
  • Replace the camshaft oil control valve for bank 1 exhaust camshaft
  • Replace timing belt
  • Check the engine oil level and condition, and add more oil if needed.
  • Replace the oil filter
  • Adjust the engine timing
  • Replace the damaged catalytic converter

Where is the B camshaft position sensor?

The camshaft position sensor notes the rate at which the camshaft is spinning and helps the car’s computer control things like fuel injection and engine timing. Note that the “B” means that this sensor is located on the exhaust side of the cylinder head.
