P102B — Torque Limited Due to Engine Oil Temperature

System: Powertrain  |  Type: Manufacturer-Specific  |  Make: Volkswagen

About P102B

P102B is a manufacturer-specific powertrain diagnostic trouble code recorded for Volkswagen vehicles. It belongs to the P-prefix family of codes, which covers engine, transmission, emissions, or fuel-system faults.

Scanning & clearing: A generic OBD-II scan tool will usually read and clear powertrain (P) codes. For live data, freeze-frame capture, and bi-directional tests you may need a more capable scan tool that supports the vehicle's ECM protocol.

P102B 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

On this Volkswagen application the engine control module monitors engine oil temperature through the oil temperature sensor and calculates the maximum allowable engine torque based on temperature thresholds in the engine software. DTC P102B is logged when the oil temperature is outside its optimal operating range, either too cold to provide adequate lubrication or too hot, risking oil breakdown and engine damage, and the module reduces available torque to protect the engine. This is often a protective response to an underlying oil temperature or cooling problem rather than a fault in the torqu...
