Circuit Description

WARNING: This page is about a different car, the 2004 GMC Sierra, 2004 GMC Cab & Chassis Sierra, 2004 Chevrolet Silverado, and 2004 Chevrolet Cab & Chassis Silverado. However, it is still accessible from the selected car via links, so may be relevant.

The engine control module (ECM) reads analog data from the accelerator pedal position (APP) sensor and processes the analog data into digital data in order to interface with the powertrain software. If the ECM microprocessor can not perform this task, this DTC will set.
