P0013 — Instant Answer
Exhaust Camshaft Position Actuator Circuit (Bank 1)
Severity: MEDIUM SEVERITY
Meaning: The ECM detected a fault in the exhaust camshaft VVT solenoid circuit on bank 1. This solenoid controls exhaust valve timing for optimal performance and emissions.
Safe to drive? Usually yes with caution, but confirm root cause before long trips.
Estimated repair cost: $25 - $120
Most common causes:
- 1. Faulty exhaust VVT solenoid (35-45% of cases)
- 2. Wiring damage (10-25% of cases)
- 3. Low oil pressure (10-25% of cases)
- 4. ECM fault (5-10% of cases)
Symptoms
- ⚠️Check engine light
- ⚠️Rough idle
- ⚠️Reduced performance
- ⚠️Poor fuel economy

Related Codes
The engine computer cannot control the variable valve timing solenoid on bank 1. This affects engine performance and fuel economy. Usually caused by a faulty VVT solenoid or wiring issue.
The exhaust camshaft on bank 1 is more advanced than the ECM expects. Usually caused by sludged oil blocking the VVT actuator or a stuck solenoid.
The intake camshaft on bank 1 is more advanced than the ECM commanded. This typically means the VVT system is stuck or the oil flow is restricted. Often caused by dirty oil or a stuck VVT solenoid.
