P267E: Bank 2 Rocker Arm Actuator Position Sensor Intermittent/Erratic
The P267E code indicates that the powertrain control module (PCM) has detected an intermittent or erratic signal from the rocker arm actuator position sensor on Bank 2. This sensor monitors the position of the rocker arm actuator, which controls variable valve lift or cylinder deactivation. An intermittent signal can cause improper actuator operation, leading to reduced engine performance, increased emissions, and potential engine damage if not addressed.
01. Most Common Causes
- Faulty rocker arm actuator position sensor
- Wiring or connector issues (chafed, broken, or corroded wires)
- Intermittent short or open in the sensor circuit
- Failed rocker arm actuator assembly
- PCM software or hardware malfunction (rare)
02. Symptoms You Will Notice
- Check Engine Light illuminated
- Rough idle or misfire
- Reduced engine power or hesitation
- Poor fuel economy
- Engine may run in fail-safe mode
03. Step-by-Step Diagnosis
Step 1: Scan for codes and record freeze frame data to capture conditions when the code set.
Step 2: Visually inspect the rocker arm actuator position sensor connector and wiring for damage, corrosion, or loose connections.
Step 3: Use a multimeter to check sensor resistance and voltage supply (typically 5V reference, ground, and signal). Compare to manufacturer specs.
Step 4: Perform a wiggle test on the wiring harness while monitoring the signal with a scan tool to reproduce the intermittent fault.
Step 5: If sensor and wiring are okay, test the rocker arm actuator itself for proper operation using a bi-directional scan tool.

05. Frequently Asked Questions
Is it safe to drive with this code?▼
It is not recommended to drive long distances with this code, as it can cause engine performance issues and potential damage to the valve train. Have it diagnosed promptly.
How much does it cost to fix?▼
The cost typically ranges from $50 to $150 for diagnosis, plus parts and labor. Sensor replacement can cost $100-$300, while actuator replacement may be $200-$500.
