Code B0160 Pontiac Description

The B0160 diagnostic trouble code (DTC) for Pontiac vehicles indicates a fault with the Ambient Air Temperature (AAT) sensor reading being too high. The AAT sensor is responsible for measuring the temperature of the air outside the vehicle and providing this information to the engine control module (ECM). This data is crucial for the ECM to adjust fuel mixture, ignition timing, and other engine parameters to optimize performance and fuel efficiency.
