<<See All OBD Codes

Error Code P0015 is defined as Camshaft Position B – Timing Over-Retarded (Bank 1). This refers to variable valve timing (VVT) or variable camshaft timing (VCT) components and the vehicle’s powertrain control module (PCM or ECM).

This error code is actually a generic code that indicates the PCM (or ECM) has determined a problem in the exhaust camshaft timing in bank 1. The problem refers to the camshaft timing, in which it’s over-retarded (delayed) compared to where it should be. This over-retarded issue can occur in either advancing or retarding phase. This means the camshaft and crankshaft timing is off, and that the camshaft is behind from where it should be in relation to the crankshaft. This primarily causes issues with the overall running of the vehicle and potentially impacts engine performance.

What causes this problem with the "B" Camshaft Position -Timing Over-Retarded?

• The variable camshaft timing oil control valve can be stuck in the open position
• The camshaft phaser is stuck in the retarded position because of damaged or clogged oil passages
• Oil flow problems to the VCT piston and phasor from incorrect oil viscosity
• The OCV or the ECM might have an open circuit

1. Camshaft & Parts - Are you facing some major issues with your camshaft? Don’t Worry! We are here to help you out.
2. Fuel Solenoid Coil - Solenoid fuel shut off valves are used to close the main jet or main fuel circuit in the carburettor when the key is turned off. Thus, it directly hampers the fuel delivery system if faulty. Visit Parts Avatar today as replace old fuel solenoids.
3. Auto Switches & Sensors - Common causes behind that P0015 error code can be defective switches or faulty sensors. So, it will be a good decision to replace them now.
4. Powertrain Control Module - P0015 error code also relates to problems with the powertrain. If the PCM is damaged it needs replacement or reprogramming. Find all the Powertrain related parts with us.
5. Oil Control Valve - A lot of issues can arise do to defective oil control valve. Did you just see P0015 code flashing? Now you know the reason why it is appearing. Get it inspected and replaced on time.
6. Diagnostic Tool - In order to detect the error, one needs high grade diagnostic tools. Visit us today to buy quality tools and equipment.

You might be thinking that how would you diagnose these problems? We at Parts Avatar Canada would help you diagnose the major symptoms easily.

Common Symptoms

• The check engine light would start appearing if the timing is commanded to move, but it stays retarded
• The engine may have to face a hard start and low power condition due to retarded timing position
• The engine might start stalling, hesitation, and running rougher than normal

The main component to check in this error code is the performance of the VCT solenoid.

• If the variable valve timing oil flow control valve solenoid is defective, then you need to replace it. If this still doesn't solve the problem, then there must be a problem in your cam phaser (stuck open) and may need replacement
• Oil and filter change is extremely important when you replace either the phaser or the oil flow control valve, as dirty oil may cause a build-up of sludge in the valve and phaser
• Also, make sure you refer to your vehicle specific manual before you perform any tests for the variable camshaft timing unit. Dealers and technicians usually have the necessary tools to thoroughly diagnose and conduct repairs for this error code

• To diagnose the vehicle with this error code, technicians conduct a visual inspection of the connections and wiring of the OCV. He will then check the engine oil to see if it still has the correct viscosity and that there’s enough oil in the engine
• Of course, technicians will use an advanced scan tool to check the status of the VVT oil flow valve. Typically, it should be on at higher engine RPM and off at idle
• He will also scan and document the engine codes and check the freeze frame data to see exactly where the code was set
• The technician will then reset the Check Engine light and test drive the vehicle to see if the code re-appears
• He will also command the OCV on and off with the scan tool to see if the timing of the camshaft changes
• Many vehicles provide a manufacturer’s test for this error code, and their troubleshooting can usually narrow down to the root cause of problem

Doing the diagnosis and troubleshooting the wrong way may lead to internal engine damage. It is crucial to have an expert technician check your vehicle for this error code.

Common Mistakes When Diagnosing the P0015 Code

When diagnosing for this error code, make sure you verify the failure and codes before you start to conduct any repairs.

• It is crucial to conduct a visual inspection and check the wiring and connections of the components
• Prevent misdiagnoses of good components by following the pinpoint steps test
• Replace components only as needed based on your thorough visual test or pinpoint tests
