Code Definition

B132F (81) — Air Conditioning High Pressure Circuit Fault – Invalid Signal

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

About B132F

B132F 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 B132F is stored, the module has detected a signal or supply voltage higher 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.

B132F 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 and the climate control module on the affected Peugeot monitor the air conditioning high pressure transducer to keep refrigerant system pressure within safe operating limits and to manage compressor cycling and condenser fan speed. The high pressure transducer is normally a three wire device with a 5V reference, signal ground, and a linear signal output, mounted on the high side refrigerant line near the condenser or receiver drier. DTC B132F:81 is set when the module detects an invalid or implausible signal from the high pressure transducer, with the :81 sub code in UDS notation typic...
