P264E: A Rocker Arm Actuator Position Sensor Circuit Intermittent/Erratic Bank 1
Standardized SAE J2012 code · P26xx — Computer and output circuits
What does P264E mean?
The position sensor signal jumps or drops out intermittently. Usually a loose connector or a chafed wire in the harness.
The code tells you which monitor failed, not which part is broken. Test before replacing parts.
Common causes
- High Sensor connector not fully seated
- Medium Harness chafed against valve cover or cam carrier
- Low Connector with intermittent contact under vibration
Likelihood is a general estimate across vehicles; your make and model may differ.
Add your car to see reports of P264E on the same make and model first.
