Solving the P2135 Code on Your Chevy Silverado

AvatarByCarl Frisch

The P2135 code is a diagnostic trouble code (DTC) that applies to the Chevy Silverado. This code indicates a problem with the throttle/pedal position sensor/switch “A” circuit, which is located on the throttle body. The throttle position sensor measures the angle of the throttle plate and sends an electrical signal to the Powertrain Control Module (PCM). If this signal is out of range, then it sets this diagnostic trouble code. Symptoms of this code include: difficulty starting the engine, stalling, engine surging, and poor performance. Common causes for this code include a faulty throttle position sensor, wiring issues, or a dirty or contaminated throttle body. In order to properly diagnose this code, a mechanic will need to use a scan tool to read live data from the Throttle Position Sensor (TPS) and compare it to factory specifications.
