About B132A

B132A is a manufacturer-specific body diagnostic trouble code recorded for Peugeot vehicles. It belongs to the B-prefix family of codes, which covers body, interior, airbag, or comfort-electronics faults.

When B132A is stored, the module has detected a signal or supply voltage lower than the expected operating range.

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.

B132A 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 BSI (the central body and convenience computer module) and the climate control module on the affected Peugeot monitor the air conditioning system pressure via a pressure transducer mounted on the high side refrigerant line, typically a three wire transducer with a 5V reference, a signal ground, and a signal output that varies linearly with system pressure. DTC B132A is set when the module detects a sensor signal voltage corresponding to refrigerant pressure below the calibrated minimum threshold for compressor operation, with a Circuit Low interpretation that may also be triggered by an el...
