Severity Level 4 — Serious
This code indicates a serious issue that can cause noticeable driveability problems and potential engine damage if not addressed. The vehicle should be taken to a mechanic as soon as possible. Extended driving is not recommended.
Common Symptoms
- The camshaft position sensor is not operating as designed
- Warning light or malfunction indicator related to the camshaft position sensor is illuminated
- Check Engine Light illuminated
- Diagnostic trouble code (DTC) stored in module memory
Possible Causes
- Faulty camshaft position sensor — most common cause, test before replacing
- Damaged or corroded wiring/connector in the camshaft position sensor circuit
- Blown fuse or faulty relay for the camshaft position sensor
- Poor ground connection — check and clean all related ground points
- Control module fault — rare but possible, only consider after ruling out simpler causes
Common Fixes
- Scan vehicle with a professional-grade OBD2 scanner to read all stored codes and freeze frame data — note the conditions when the code set ($44-110 at shop, free at auto parts store for basic scan)
- Visually inspect the camshaft position sensor wiring harness and connectors — look for chafed wires, melted insulation, green corrosion, loose pins, or rodent damage (often free to check yourself, $78 diagnostic fee at shop)
- Replace camshaft position sensor if testing confirms it has failed — use OEM quality, avoid the cheapest no-name aftermarket parts that fail in a year ($50-350)
- Check and replace any blown fuses in the camshaft position sensor fuse circuit — if fuse blows again, there's still a short that needs to be found ($5-20 for fuses)
- Perform a wiggle test on the camshaft position sensor wiring harness while monitoring live data — see if the fault returns when you move the harness at different points ($0-105 diagnostic labor)
