P267D — Rocker Arm Actuator Position Sensor Circuit High #

Note: The description for this DTC may vary depending on the vehicle manufacturer.

• P267D: Rocker Arm Actuator Position Sensor Circuit High (Generic/SAE)
• P267D: Intake Rocker Arm Actuator Position Sensor Circuit High (GM, Ford)
• P267D: Exhaust Rocker Arm Actuator Position Sensor Circuit High (Honda, Acura)

Summary of DTC P267D #

The P267D diagnostic trouble code indicates that the engine control module (ECM) has detected a high voltage signal in the rocker arm actuator position sensor circuit. This sensor monitors the position of the rocker arm actuator, a component that helps control variable valve timing (VVT) in modern engines. When the circuit voltage exceeds the OEM’s specified threshold, the ECM logs this code. The issue can be related to electrical faults or mechanical problems in the actuator or sensor. While not always urgent, this code signals a condition that can impact engine performance and efficiency.

Common Symptoms for DTC P267D #

When P267D is present, symptoms may range from subtle to more pronounced, depending on the severity and whether the actuator is stuck or the sensor is merely sending incorrect data. Drivers and technicians often report:

• Check Engine Light illuminated on the dashboard
• Rough idle or unstable engine RPMs
• Reduced engine performance, especially at certain RPMs
• Decreased fuel efficiency
• Occasional hesitation or stumbling on acceleration
• Possible increased emissions or failed emissions test

Probable Causes for DTC P267D #

Several underlying issues can trigger a high voltage reading at the rocker arm actuator position sensor circuit. Statistically, the most common causes, in order of frequency, are:

1. Faulty rocker arm actuator position sensor (internal short or open circuit)
2. Damaged or corroded wiring/connectors related to the sensor
3. Electrical short to voltage in the circuit harness
4. Failed rocker arm actuator itself (mechanical or electrical malfunction)
5. ECM/PCM issue (rare, but possible if all else tests good)

Step-by-Step Diagnosis for DTC P267D #

Diagnosing P267D requires a systematic approach, blending visual inspection with targeted electrical testing. Here’s a recommended workflow:

• Verify the code with a scan tool and check for accompanying DTCs (especially related to VVT or actuator circuits).
• Visually inspect the rocker arm actuator position sensor and related wiring for obvious damage, corrosion, or loose connectors.
• Check sensor voltage and compare live data readings to OEM specifications using the scan tool.
• Test circuit continuity from the sensor to the ECM, looking for shorts to voltage or ground.
• Bench-test the actuator and sensor if possible, or swap with a known good component (if available and safe to do so).
• Clear the code and perform a road test to see if P267D returns.
• If all tests pass but the code persists, consider an ECM software update or replacement as a last resort.

Possible Repairs for DTC P267D #

The repair strategy should match the root cause identified during diagnosis. Typical fixes include:

• Replace the rocker arm actuator position sensor if it tests faulty or out of spec.
• Repair or replace damaged wiring/connectors in the actuator sensor circuit.
• Fix any short to voltage or ground in the harness.
• Replace the rocker arm actuator if it’s determined to be defective.
• Update or reprogram the ECM if a technical service bulletin (TSB) applies, or replace if proven necessary.

Is It Safe to Drive with P267D? #

Limited — Exercise Caution. While P267D does not usually indicate an immediate threat to engine health, driving for extended periods with this code can lead to reduced engine performance and potentially increased engine wear or emissions issues. If you experience severe symptoms like rough running, poor acceleration, or engine stalling, it’s best to address the issue before further driving.

Vehicles Most Commonly Affected by P267D #

This code is most frequently seen in vehicles equipped with advanced variable valve timing systems. Automakers known to use this specific DTC include:

• General Motors (Chevrolet, GMC, Cadillac, Buick)
• Ford (including Lincoln, Mercury)
• Honda/Acura
• Toyota/Lexus (less common, but possible on select models)
• Chrysler/Dodge/Jeep (occasional on newer platforms)

Common Mistakes & Best Practices for P267D #

Errors in diagnosing or repairing P267D can lead to unnecessary part replacements or persistent issues. Stay sharp by avoiding these pitfalls and following established best practices:

• Do not replace the sensor or actuator without testing — always verify with measurements and visual inspection first.
• Check wiring and connectors carefully, especially for signs of corrosion, pin damage, or water intrusion.
• Don’t overlook software updates or TSBs that may address this code.
• Document all findings and repairs for future reference and warranty purposes.

Quick FAQ for P267D #

Have more questions? Here are some quick answers:

• Q: Can a weak battery cause DTC P267D?
  A: While rare, abnormally low system voltage can sometimes affect sensor readings. However, P267D is usually the result of a circuit or sensor issue.
• Q: Will clearing the code fix the problem?
  A: Clearing the code will reset the warning light, but if the underlying issue is not fixed, P267D will return quickly.
