B1267 OBD-II Trouble Code: Servo Motor Airintake Right Circuit Failure

diagnostic check engine light

B1267 code definition

The B1267 trouble code detects a malfunction with the servo motor air intake right circuit.

What the B1267 code means

The B1267 code is a generic OBD-II trouble code that notes a circuit failure with the servo motor air intake right. This servo motor helps control half of the air flow into the interior of the vehicle (there are two servo motors, the “right” and the “left”). The servo motors are critical parts of the heating, ventilation, and air conditioning (HVAC) module, as they allow both hot and cold air to enter the cabin. When the HVAC module or the body control module notes a servo motor right circuit failure, then the B1267 code will be stored.

What causes the B1267 code?

The B1267 trouble code can be caused by a few different things:

What are the symptoms of the B1267 code?

The B1267 trouble code may be accompanied by the check engine soon Warning Light, or by a flashing light on the climate controls. There will likely be issues with the climate control system, such as an inability to provide hot air, an inability to provide cold air, or the presence of only recirculated air.

How does a mechanic diagnose the B1267 code?

The B1267 code will be diagnosed using a standard OBD-II trouble code scanner. A trained technician will use the scanner to view the freeze frame data for this code, and to check for any additional trouble codes that are present. If the mechanic finds numerous trouble codes, then they should be addressed in the order in which they appear. Next, the technician should reset the trouble codes, restart the vehicle, and check to see if the B1267 code is still present. If it is not, then it was likely erroneously triggered, or the result of an intermittent error.

If the B1267 code remains detected, then the mechanic should begin by visually inspecting the electrical components in the system. Any shorted wires, open or corroded connectors, or blown fuses will need to be replaced. The right temperature vent flaps should then be examined, followed by the servo motor.

After any component is replaced, the mechanic will need to again reset the trouble codes, restart the vehicle, and check for the B1267 code. This will help the mechanic know when the issue is resolved.

Common mistakes when diagnosing the B1267 code

The most commonly made error when diagnosing the B1267 trouble code comes from a failure to follow the OBD-II diagnosis protocol. It is imperative that the protocol by complied with at all times, as this ensures diagnoses and repairs that are efficient.

Servo motors are often unnecessarily replaced because electrical components were not first inspected.

How serious is the B1267 code?

A vehicle with the B1267 trouble code will still be perfectly drivable, but the climate control system will likely be compromised. A vehicle with this code should be inspected sooner rather than later.

What repairs can fix the B1267 code?

Repairs for the B1267 trouble code are:

  • Servo motor replacement
  • Replacement of electrical components
  • Fixing stuck right temperature vent flaps
  • In rare cases, replacement of control modules

Additional comments for consideration regarding the B1267 code

The B1267 trouble code will very rarely be the result of a defective control module. All other options should be exhausted before control module failure is assumed. If a control module does require replacement, then it will also need to be reprogrammed.
