A variable valve timing (VVT) system of your vehicle improves fuel economy and engine efficiency. This system uses to regulate the closing and opening of the intake valve and exhaust valve to control the air-fuel mixture. It also improves the overall performance of your vehicle. The PCM activates code P0014 only on vehicles that have variable valve timing (VVT).
The DTC P0014 code is related to an issue with the camshaft timing, specifically the “B” position of the Bank 1 exhaust camshaft. This exhaust camshaft controls the valve that uses to release the engine exhaust gases. This article explains the symptoms, causes, and meaning of the P0014 code.
Code P0014 Definition
- P0014 Generic: Exhaust Camshaft Position—Timing Over—Advanced or System Performance (Bank 1)
- P0014 Hyundai: Blink Code: 3,3 Open circuit to Front left outlet valve
- P0014 Peugeot: Camshaft Position B → Over Advanced → Bank 1
- P0014 Kia: Blink Code: 3,3 Open circuit to Front left outlet valve.
What Does P0014 Code Mean?
The P0014 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.
The trouble code P0014 is related to the engine’s variable valve timing. A variable valve timing system helps to improve engine performance and fuel economy by adjusting the closing and opening timing of the exhaust valve and intake valve.
The PCM controls the camshaft using an oil control valve (OCV), also known as a variable valve timing control solenoid valve. As the P0014 is triggered, it indicates that the exhaust camshaft in Bank 1 is ahead of the engine computer has told it to be.
Symptoms of the P0014 Code
As the PCM triggers the P0014 code, you will notice one or more below given symptoms:
- Check engine light illumination
- Rattling/Knocking from engine
- Failed emission test
- Engine misfiring
- Poor engine performance
- Engine stalling
- Starting issues

Causes of P0014 Code
There are multiple causes of the P0014 code, but the following are the major causes:
- Bank 1 camshaft oil control solenoid valve may be shorted open.
- A bad camshaft position sensor
- Dirty engine oil
- The camshaft phaser is stuck in the advanced position.
- Incorrect oil viscosity
- Insufficient engine oil
- Bad or damaged Variable Camshaft Timing Solenoid Valve
- The oil viscosity is too high and is blocking the passages, restricting oil flow to or from the camshaft phaser.
- Nonstop oil supply to variable camshaft timing chamber
- An issue with the PCM
- The exhaust camshaft is too advanced when the PCM commanded the camshaft to retard to reduce the timing level.

Common P0014 Code Diagnosis Mistakes
You must avoid the below-given mistakes when diagnosing or fixing error code P0014:
- Scan your car with an OBDII scanner, clear fault codes, and then scan the vehicle again. You can drive for about 14 to 21 minutes before scanning again. If the code persists, continue with additional diagnostics and troubleshooting.
- Make sure the engine oil is full and clean. Your oil must have sufficient viscosity.
- Inspect the connectors and wiring harnesses to confirm they are not corroded.
- Obtain the service manual for your definite car and follow the manufacturer’s testing steps to diagnose or repair your car efficiently.
- Don’t replace or repair any part except diagnostics that have proven the fault.
How to diagnose the P0014 Code?
You must have the following tools to diagnose or fix the P0014 code:
- Fused jumper wires
- Specific vehicle service manual
- OBDII scan tool
- Basic hand tools
Follow the below-given steps to diagnose the P0014 code:
- Run a scan check, check for other codes with P0014, and clear the engine warning light with a scan tool.
- Visually inspect the valve or connector for problems with the bank 1 exhaust camshaft OCV.
- The damaged wiring is one of the common causes of the P0014 code. When checking the wiring, make sure there are no damage or scratches to the wiring.
- 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. If the oil has low viscosity or contamination, then replace it,
- Inspect and install a new filter if needed.
- 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.
- If your engine doesn’t have debris, then check the exhaust camshaft oil control valve located at Bank 1 for proper operation. This test can be performed by unscrewing the OCV from the camshaft and testing it using a jumper. Power and ground are transmitted to the solenoid through a pair of fusible wire jumpers.
- If your OCV is working properly, you will hear a click, and the valve will move in both directions. If it doesn’t generate clicking noise or movement, replace it and perform a test drive to see the results.
- If P0014 appears again after performing all the above diagnosis steps, you may have internal engine problems. Contact a technician to diagnose and fix it.
Note: You must follow the recommended pinpoint tests of the manufacturer to narrow down the issue because each engine may be tested differently.
What repairs can fix the P0014 code?
- Reset the fault code and perform a road test
- Replace or repair the timing chain
- Check the engine oil level and condition, and add more oil if needed.
- Adjust the engine timing if needed.
- Replace the oil filter if needed
- Replace the damaged catalytic converter if needed.
- Replace the camshaft oil control valve for bank 1 exhaust camshaft
- Repair or replace the damaged wires connected to the camshaft oil control valve for bank 1 exhaust camshaft
Repair Costs for P0014 Code
To fix or repair the P0014 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.
|Oil Control Valve||$310 to $410|
|Oil Change||$40 to $70|
|Engine||$2900 to $4100|
How serious is the P0014 code?
- Due to this code, your engine may run erratically, stall, or have difficulty starting.
- It increases fuel consumption and can lead to carbon deposits on pistons and engine valves.
- If you drive with the P0014 code or a worn camshaft for a long time, the timing belt can come loose from the teeth, and the valve can touch the piston.
Can I drive a car with a P0014 Code?
Yes, you can continue driving your vehicle with P0014. However, it is recommended to check and fix the code by an expert as soon as possible. Driving with this code can cause hard starts, poor fuel economy, poor engine performance, stalling, and erratic idling.
Driving with a faulty camshaft position sensor can cause many problems, including poor fuel economy, poor engine performance, and engine misfires.
Can too much oil cause P0014?
Too much oil in your car engine can cause increased engine pressure, fouled sparks, collapsed valve hoses, and other problems.
Excessive oil flow can cause clogging and foaming in the oil area, causing lubrication problems. Oil flow must be restricted to keep the engine running smoothly and efficiently.
What causes timing over advanced?
- Bad oil control solenoid
- Damaged timing components
- A failed camshaft actuator (aka phaser)
- A low engine oil level or contaminated oil (very common)
Can an oil change fix P0014?
An oil change may fix the problem if the code is due to a bad oil filter. However, if the code is caused by something else, e.g., a leak or a problem with the engine controls, changing the oil may not fix the problem.
How many camshaft position sensors does a car have?
Camshaft sensors determine the position of the camshaft and send this data to the PCM. The latest engines have camshaft sensors on each camshaft. A car with a common engine (a four-cylinder engine) has four camshafts and one sensor per camshaft. Other types of engines such as V6, V8, and V12 have different numbers of sensors.
How long does it take to change a camshaft sensor?
Replacing a camshaft position sensor typically takes between one and two hours. However, this may vary depending on the make and model of your vehicle.
