About B1032

B1032 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 B1032 is stored, the module has detected an open (broken or disconnected) electrical path 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.

B1032 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 Thermo Sensor on Mitsubishi vehicles is a negative temperature coefficient (NTC) thermistor used by the climate control system to measure cabin, ambient, or discharge air temperature depending on its location within the HVAC ducting. The climate control module applies a reference voltage through an internal pull up resistor and reads the resulting divided voltage across the sensor to calculate temperature. DTC B1032 is set when the climate control module detects that the sensor signal voltage has risen above the expected maximum threshold, indicating an open circuit condition such as a...
