What does fault code P0013 mean?
The P0013 fault code, applicable to all car manufacturers, means “B Camshaft Position – Actuator Circuit/Open (Bank 1)“.
Background Information: The camshaft controls the opening and closing of the valves. In a variable valve timing system, the electronic camshaft adjusting valve (or oil control valve, OCV) adjusts the camshaft angle by changing the oil pressure to the camshaft adjuster (mechanical type) according to instructions from the engine control module (ECM), ensuring the valves open and close at optimal times. Possible causes of the P0013 fault include problems with the B exhaust/right/rear camshaft adjusting valve (oil control valve), its circuitry, connectors, excessively dirty oil, or the ECU. “B” camshaft must refer to the “exhaust,” “right,” or “rear” camshaft. Determine left/right and front/rear from the driver’s position using forward visibility. Bank 1 refers to the group including cylinder 1, and Bank 2 is the group opposite Bank 1.
Symptoms of P0013 Error Code
When the P0013 code appears, the following signs may be observed:
- Engine malfunction indicator light illuminates
- Unstable engine idle
- Reduced engine power
- Difficulty starting the engine
- Increased fuel consumption
- Engine stalls when stopped
- Metallic noise from the timing system
Main Causes of P0013 Error Code
- Faulty Variable Valve Timing (VVT) solenoid
- Damaged wiring or solenoid connector
- Short circuit or open circuit
- Valve or oil passage contamination
- Engine Control Unit (ECU) problem
- Using incorrect or dirty engine oil
P0013 Error Code in Different Vehicles
Chevrolet Cruze P0013: The error is usually caused by wear or contamination of the solenoid valve. Replacement or cleaning is required. Checking the oil quality is also important.
Kia Rio P0013: The main cause is solenoid valve failure. Replacement or flushing usually helps. Resistance and voltage will be checked.
Hyundai Elantra P0013: Causes include damaged wiring harness or broken contact. Replacing the solenoid valve and connector usually helps.
Opel Astra P0013: The error occurs when the engine oil is old or the valve is clogged. Comprehensive maintenance of the VVT valve is required, and replacement may be necessary.
Ford Focus P0013: There may be connector problems or oil contamination. Checking the tightness and integrity of the wiring is very important.
How to Diagnose P0013 Error Code?
Step 1: Read the error code using an OBD2 scanner.
Step 2: Check the wiring and connector of the VVT solenoid valve.
Step 3: Check the oil level and condition.
Step 4: Measure the resistance of the VVT valve with a multimeter.
Step 5: Clean or replace the valve if necessary.
| Possible Causes | How to Check? |
|---|---|
| Solenoid valve malfunction | Measure the resistance with a multimeter and compare it to the normal value |
| Valve or oil passage contamination | Remove the valve for inspection and clean if necessary |
| Open circuit or short circuit | Visual inspection of the wiring, circuit continuity test |
| Control unit (ECU) malfunction | Scanner diagnosis, parameter comparison |
| Low oil level or old engine oil | Check the oil level and condition |
Tools needed: OBD diagnostic tool, multimeter, wrench set, engine parts cleaner
How to fix P0013 error code? (Solutions to the problem)
Simple troubleshooting methods
- Reset the error code with a scanner and see if it reappears.
- Check and top up the engine oil (if needed).
- Change the engine oil and oil filter.
- Clean the valve connector and wiring.
In-depth diagnostic and repair solutions
- Replace the variable valve timing (VVT) solenoid valve.
- Repair or replace damaged wires.
- Check the engine control unit (ECU).
- Flush the engine lubrication system.
| Symptoms | Possible solutions |
|---|---|
| Engine instability | Check and replace the VVT valve |
| Engine malfunction light is on | Read and correct the error, reset the code |
| Reduced engine power | Check oil pressure, change oil |
| Increased fuel consumption | Clean or replace the valve, perform maintenance |
P0013 Error Frequently Asked Questions
Is it possible to continue driving with error P0013?
It is not recommended, as the malfunction may lead to reduced engine performance and increase the risk of engine damage.
Can I fix the P0013 error myself?
Yes, in some cases you can clean or replace the VVT valve, check the wiring, and change the oil. However, without a proper diagnosis, it’s difficult to determine the exact cause.
Is the P0013 error related to oil quality?
Yes, old or dirty oil can cause the valve timing valve to malfunction, leading to the error.
How do I reset the P0013 error code?
The code can be reset using an OBD2 scanner or by temporarily disconnecting the battery. However, if the cause of the malfunction is not resolved, the error will reappear.
How dangerous is the P0013 error for the engine?
If the error is ignored for a long time, it can be dangerous because the valve timing will be disrupted, which may damage the engine over time.
Related OBD2 Errors:
P0010 – A Camshaft Position Actuator Circuit/Open (Bank 1))
P0011 – A Camshaft Position – Timing Over-Advanced or System Performance (Bank 1)
P0023 – B Camshaft Position – Actuator Circuit/Open (Bank 2)
Important! Ignoring this error can lead to serious engine consequences, including damage to the camshaft or other timing components. Regularly change the engine oil and monitor its quality. This will not only help prevent P0013 but also other critical errors related to the VVT system.
