P0010 — Camshaft Position Actuator Circuit (Bank 1)

P0010 means the engine control module detected an electrical problem in the variable valve timing actuator circuit. The most common cause is a failed actuator solenoid or a wiring issue.

Moderate

The engine will run but may idle roughly, lack power at certain RPM ranges, and consume more fuel. The VVT system defaults to a fixed timing position.

What P0010 means

The variable valve timing system uses oil pressure controlled by an electronically operated solenoid to advance or retard the camshaft timing. The module monitors the solenoid circuit for opens, shorts, and excessive current draw. P0010 sets when the electrical signal from the actuator circuit is outside the expected range, which prevents the VVT system from adjusting timing and can cause rough running, poor fuel economy, or reduced power.

The module injects fuel to match the measured air, and the upstream oxygen sensor reports the result so it can correct itself.

Symptoms you may notice

What causes P0010

VVT actuator solenoid has failed

Very likelylow costeasy

The solenoid coil can open or short internally, which the module detects as an out-of-range current. This is the most common cause, particularly on higher-mileage engines.

Wiring or connector to the solenoid is damaged

Likelylow costeasy

Chafed wires, corroded terminals, or a loose connector can cause the same electrical fault as a failed solenoid. Inspect before replacing parts.

Engine oil level low or heavily contaminated

Possiblelow costeasy

The VVT system relies on clean oil at the correct level. Sludge or low oil can cause the solenoid to stick and draw abnormal current.

How to diagnose it

1

Check engine oil level and condition

Verify the oil is at the correct level and not heavily contaminated. Low or dirty oil can cause VVT solenoid issues.

Tools: Dipstick or electronic level checkIf it passes: Oil is clean and at the correct level. Continue to step 2.If it fails: Change the oil and filter, clear the code, and re-test.
2

Inspect the solenoid connector and wiring

Unplug the VVT solenoid connector and inspect for corrosion, damage, or loose pins. Check the wiring harness for chafing or breaks.

Tools: Inspection lightIf it passes: Connector and wiring are intact. Continue to step 3.If it fails: Repair the wiring or connector, clear the code, and re-test.
3

Test the solenoid resistance

Measure the resistance across the solenoid terminals with a multimeter. Compare against the manufacturer specification, typically 6-15 ohms.

Tools: MultimeterExpected: 6-15 ohms (varies by manufacturer)If it passes: Resistance is within specification. The wiring or module may be the fault.If it fails: Resistance is open or shorted. Replace the solenoid.

Common questions

Can I drive with P0010?

Yes, the engine will run, but with reduced performance and fuel economy. The VVT system defaults to a fixed timing position.

Is P0010 serious?

It will not cause immediate damage, but ignoring it long-term means you are paying for fuel you do not need and the engine is not running at its designed efficiency.
