B1041 — Air Mixing Damper Control Motor Position Sensor Signal Circuit Shorted to Power

System: Body  |  Type: Manufacturer-Specific  |  Make: Mitsubishi

About B1041

B1041 is a manufacturer-specific body diagnostic trouble code recorded for Mitsubishi vehicles. It belongs to the B-prefix family of codes, which covers body, interior, airbag, or comfort-electronics faults.

When B1041 is stored, the module has detected a short-circuit (voltage pulled to ground or to supply) in the monitored circuit; and a sensor-related fault — the reported value from the named sensor is out of spec.

Scanning & clearing: Body (B) codes are often stored in the body control module, airbag module, or climate module. A basic OBD-II tool usually will not read body codes — an enhanced or OEM-level scan tool is typically required.

B1041 is a manufacturer-specific code. The same code string on a different make may have a different meaning. Always confirm the code's definition against the vehicle's service information for the specific make and model under test.

Code Information

The Air Mixing Damper on Mitsubishi vehicles is the blend door inside the HVAC case that proportions air flow between the heater core and the evaporator to achieve the target discharge temperature. The damper is driven by a small electric motor that includes an internal position feedback sensor, usually a potentiometer wiper, which reports the current damper angle back to the climate control module on a signal wire. DTC B1041 is set when the climate control module reads the position sensor signal voltage pegged high at or near battery voltage, indicating the signal is shorted to a power source...
