P0010: "A" Camshaft Position Actuator Circuit (Bank 1)
Moderate SeveritySafe to drive (short-term)Electrical
P0010 means the engine control module has detected an electrical fault in the variable valve timing solenoid circuit for the intake camshaft on bank 1. This solenoid controls oil flow to the cam phaser, adjusting camshaft timing for optimal engine performance, fuel efficiency, and emissions.
What does P0010 mean?
P0010 means the engine control module has detected an electrical fault in the variable valve timing solenoid circuit for the intake camshaft on bank 1. This solenoid controls oil flow to the cam phaser, adjusting camshaft timing for optimal engine performance, fuel efficiency, and emissions.
P0010 is a electrical-related diagnostic trouble code classified as moderate severity. When your vehicle's ECU detects this condition, it stores P0010 and illuminates the check engine light.
What are the symptoms of P0010?
If your vehicle has triggered P0010, you may notice one or more of these symptoms:
Check engine light illuminated
Rough idle or unstable engine speed
Reduced fuel economy
Slight loss of power, especially at low RPM
Hard starting in cold weather
What causes P0010?
Here are the most common causes of P0010, ranked by how likely they are to be the culprit:
highFaulty VVT/camshaft position actuator solenoid
highWiring damage or corroded connector at the solenoid
mediumLow or dirty engine oil restricting oil flow to the solenoid
lowFailed ECU driver circuit (rare)
mediumOil sludge buildup in oil passages
Is it safe to drive with P0010?
Generally yes, for short-term driving. You can drive short distances to a workshop, but the engine may run roughly and fuel economy will suffer. Avoid high-RPM driving until repaired.
How do you diagnose P0010?
Follow these steps to pinpoint the root cause of P0010:
Check engine oil level and condition. If the oil is dark, sludgy, or low, perform an oil change first and recheck
Locate the VVT solenoid on bank 1 (usually on the valve cover near the front of the engine) and inspect the electrical connector for corrosion or damage
Use a multimeter to measure the solenoid resistance (typically 6-13 ohms). If out of range, replace the solenoid
Check wiring continuity between the ECU and the solenoid connector. Repair any open or shorted circuits
Use a scan tool to command the solenoid on and off. Listen for a clicking sound and verify oil pressure changes at the solenoid

P0010 on BMW 3 Series
BMW 3 Series • 2005-2024
BMW VANOS solenoids on the N52 and N54 engines are a common failure point. BMW calls this the VANOS actuator solenoid. Oil quality is critical - always use BMW LL-04 approved oil. The solenoid is located on the front of the cylinder head.

P0010 on Volkswagen Golf
Volkswagen Golf • 2006-2024
The EA888 engine uses a camshaft adjuster solenoid that can fail due to oil contamination. VW recommends oil changes every 15,000 km but many mechanics suggest 10,000 km intervals for turbo engines to prevent sludge-related VVT issues.

P0010 on Toyota Corolla
Toyota Corolla • 2008-2024
Toyota's VVT-i system on the 1ZR-FE and 2ZR-FE engines is generally reliable, but the oil control valve (OCV) can stick if oil changes are neglected. Toyota uses the term OCV rather than VVT solenoid. The part is inexpensive and easy to access.

Related diagnostic codes
These codes are often seen alongside P0010 or indicate related issues:
You can drive short distances to reach a workshop, but avoid prolonged driving or high RPMs. The engine may idle roughly and use more fuel. Continued driving without repair could lead to increased wear on the timing chain and related components.
What does the camshaft position actuator do?
The camshaft position actuator (VVT solenoid) controls oil flow to a mechanism that adjusts when the intake valves open and close. This optimises engine performance, fuel efficiency, and emissions across different RPM ranges.
Can an oil change fix P0010?
Sometimes yes. If the code was triggered by low oil pressure or sludge blocking the solenoid, a fresh oil change with the correct viscosity can restore proper operation. Clear the code after the oil change and monitor.
How much does it cost to fix P0010?
In most cases, replacing the VVT solenoid costs between 65 and 240 EUR including parts and labour. If the issue is just dirty oil, an oil change at 40-110 EUR may resolve it. Wiring repairs typically fall in the 55-180 EUR range.
