A Camshaft Position Actuator Control Circuit/Open (Bank 1)
There's an issue with the camshaft position actuator control circuit on bank 1.
Heads up: this code wasn't in our hand-written library yet, so DiagCoach AI built this page on the fly. Double-check critical specs against service info before condemning parts.
What it means (plain English)
The car's computer is getting a signal that the camshaft position actuator isn't working right, usually because of a wiring problem or the actuator itself failing.
What the computer is actually seeing
The engine control module (ECM) expects a certain voltage level to confirm the position of the camshaft, typically between 0.5V and 4.5V depending on the position. If the circuit is open or shorted, it may read as 0V or not return a proper signal.
What a healthy reading looks like
Normal operation should show a variable voltage signal between 0.5V and 4.5V as the camshaft changes position based on engine load and speed.
Guided diagnostic — the DiagCoach way
Don't just throw parts at it. Walk through these in order — each step tells you whether to keep going or stop and fix what you found.
- 11. Inspect the wiring and connectors for the camshaft position actuator. Look for fraying, corrosion, or loose connections. Decision: If everything looks fine, proceed to step 2; if not, repair or replace as needed.
- 22. Use a multimeter to measure the voltage at the actuator connector while the engine is running. Expected voltage should be between 0.5V and 4.5V. Decision: If the voltage is out of range, proceed to step 3; if within range, replace the actuator.
- 33. Disconnect the actuator and check for continuity in the wiring from the actuator connector to the ECM. Decision: If continuity is good, replace the ECM; if not, repair the wiring as needed.
Common causes
- Wiring harness damage or corrosion
- Faulty camshaft position actuator
- Defective engine control module (ECM)
- Poor connections at the actuator or ECM
Typical repair cost
$$$
