B1267 — Servo Motor Airintake Right Circuit Failure

What does OBD2 code B1267 mean?

B1267 — Servo Motor Airintake Right Circuit Failure. A fault in the body electrical system. The car is usually drivable while you plan the repair. Typical causes: body control module (BCM) fault, damaged wiring in door jambs or wet areas, corroded or loose connectors.

How do I diagnose B1267 myself?

Start with a scan: confirm B1267, save the freeze frame and note any companion codes. Then inspect the wiring and connectors related to the servo motor airintake right circuit, and verify the suspect component against live data before buying parts.

Will B1267 clear itself?

Sometimes B1267 clears after a few drive cycles if the fault was intermittent — for example a loose connector or a tank of bad fuel. The underlying cause usually remains, so the code tends to return. Clear it once; if it comes back, diagnose rather than erase it repeatedly.

How much does it cost to fix B1267?

Repair wiring or connectors — $80–$250; Replace the switch or actuator — $120–$450; BCM repair or replacement — $300–$900. Exact cost depends on the root cause, your vehicle and local labor rates — a proper diagnosis is the cheapest first step.

Is it safe to drive with B1267?

Usually safe to drive — body codes rarely affect drivability. Exceptions: exterior lighting and wipers in bad weather, and central locking faults that can leave the car unsecured.

When your OBD2 scanner pulls code B1267, it means the vehicle's control unit has detected a problem within the body electrical system. Specifically, B1267 points to a failure in the circuit that controls the right-side air intake servo motor. This code falls within the B-series category, which covers body-related electrical faults rather than engine or drivetrain issues. The control module continuously monitors the electrical circuits under its jurisdiction, and when a signal falls outside the expected range, it logs the fault and illuminates the check engine or body control warning light.

The air intake servo motor plays a role in managing airflow into the climate control system. When this circuit fails, the motor may stop responding to commands from the body control module, leaving the intake doors stuck in one position. To set B1267, the module typically needs to confirm the fault across multiple drive cycles before permanently storing the code. It also captures a freeze frame—a snapshot of engine operating conditions such as RPM, engine load, coolant temperature, and vehicle speed at the exact moment the failure occurred. Reviewing this data first helps pinpoint whether the problem happens under specific conditions like cold starts or high humidity.

Symptoms of B1267

In most vehicles, B1267 does not affect engine performance or drivability. The fault is isolated to the body electrical system, so you will continue driving normally in that regard. However, you may notice one or more of the following symptoms:

• The air intake system fails to change modes or responds sluggishly when you adjust climate settings
• The check engine light or a dedicated body control warning indicator illuminates on the dashboard
• The affected function (in this case, the right-side air intake) operates intermittently or becomes completely inoperative
• In some cases, related systems sharing the same circuit may exhibit reduced functionality
• The climate control display may show an error message or unusual readings
• You may hear unusual clicking or motor noise coming from the HVAC housing when adjusting airflow settings

Common Causes of B1267

The root cause of B1267 typically stems from one of several electrical issues. These are listed from most to least frequently encountered:

• A failed servo motor, actuator, or the switch controlling the air intake system
• Corrosion, moisture intrusion, or looseness at the electrical connectors feeding the affected motor
• Wiring damage in areas prone to flexing or exposure to moisture, particularly door jambs and hinge areas
• A blown fuse or failed relay that interrupts power to the circuit
• Physical damage to wiring from rodents, age, or improper repair work
• In rare cases, a malfunctioning body control module that fails to properly manage the circuit

How to Diagnose B1267

Diagnosing B1267 requires a systematic approach that rules out simpler causes before investigating more expensive components. Follow these steps:

1. Connect an OBD2 scanner to the vehicle's diagnostic port, confirm B1267 is stored, and record the freeze frame data. This information reveals what conditions existed when the module first detected the fault.

2. Scan for any additional trouble codes. Related codes often point toward the underlying cause—for example, a communication fault with the body control module could explain why the servo motor signal is abnormal. Check manufacturer technical service bulletins for your specific make and model, as many B0xxx codes have known factory fixes or software updates documented by the automaker.

3. Perform a visual inspection of the wiring harness and connectors associated with the right-side air intake servo motor. Look for damaged insulation, broken wires, corrosion buildup, or connectors that are not fully seated.

4. Access the live data stream on your scanner and monitor the servo motor's position sensor while commanding the motor to move. If the PID values remain static while the motor should be operating, you have confirmed an electrical failure.

5. Carefully inspect wiring at flex points, particularly where wires pass through door jambs or near moving hinges. Wires break internally at these locations even when the outer insulation appears intact.

6. After completing repairs or replacements, clear the code and drive the vehicle through a complete drive cycle that includes the conditions captured in the freeze frame. The code must not return for the repair to be considered successful.

Repair Options and Costs

B1267 repair costs vary widely depending on which component is actually at fault. Addressing the most likely causes first keeps expenses manageable:

• Wiring repair or connector replacement: $80–$250
• Servo motor, actuator, or switch replacement: $120–$450
• Body control module repair or replacement: $300–$900

The total cost to fix B1267 typically falls between $80 and $900, with most vehicles falling toward the lower end of that range. An accurate diagnosis before purchasing parts is essential—the body control module replacement scenario represents the most expensive fix and should only be considered after confirming all simpler causes are not responsible.

Can You Drive with B1267?

In most circumstances, B1267 does not prevent safe vehicle operation. Body electrical codes of this type rarely impact engine performance, braking, or steering. However, a failed air intake servo motor may leave your climate control system stuck in one mode, which can become uncomfortable or hazardous in extreme weather. Additionally, if the failure is part of a broader electrical issue affecting exterior lighting or central locking, those scenarios warrant more immediate attention. Use your best judgment based on which system is affected, and address the repair before relying on the vehicle in challenging conditions.
