What Does P267C Mean?
The rocker arm actuator position sensor circuit on Bank 2 is reading abnormally low voltage, below the expected minimum threshold. This electrical fault prevents accurate monitoring of variable valve timing operation.
Common Causes
40%
Short to ground in sensor wiring harness
35%
Failed rocker arm actuator position sensor (internal short)
15%
Damaged or corroded sensor connector causing ground fault
7%
Water intrusion or oil contamination in connector
3%
PCM internal fault or poor ground connection
Diagnostic Steps
1
Step 1: Inspect sensor connector for corrosion, oil contamination, or damaged pins; clean and repair as needed
2
Step 2: Disconnect sensor and measure voltage at harness connector with key on, engine off (should read reference voltage 5V)
3
Step 3: Test sensor resistance with sensor disconnected; compare to manufacturer specifications
4
Step 4: Perform continuity test from sensor connector to ground to check for short circuit in wiring
5
Step 5: If wiring and sensor test good, verify PCM ground circuits and consider PCM fault
Estimated Repair Cost
$150 - $800
Parts + labor, varies by vehicle and location
The rocker arm actuator position sensor circuit on Bank 2 is reading abnormally low voltage, below the expected minimum threshold. This electrical fault prevents accurate monitoring of variable valve timing operation.
The most common cause of P267C (B Rocker Arm Actuator Position Sensor Circuit Low Bank 2) is: Short to ground in sensor wiring harness
Typical repair costs for P267C range from $150 to $800, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Safe to drive for short distances but may experience reduced performance and fuel economy. Prolonged operation could damage catalytic converter.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P267C to identify the root cause.
