P2130 is the general circuit code for signal F. GM used it on its 2004-2005 pickups and SUVs with a separate throttle actuator control module (TACM) and a pedal carrying three tracks, where F is APP sensor 3. The TACM flags a continuous or intermittent open or short when sensor 3 reads below 1.63 V or above 4.38 V, or when its learned rest voltage exceeds 4.28 V; each error adds 4 to a counter checked every 3 ms, passes subtract 1, and the code sets at 106. GM's 2004 tables rate it Type C, the 2005 tables Type A with immediate MIL. Ford's three-track pedals split the same duty into P2132 and P2133. Plausibility is P2131, dropouts P2134. With one track lost the other two still steer the engine, usually with reduced response.

Likely causes

Poor terminal contact or corrosion at the pedal connector
Open or short in the signal, reference or ground wire of track F
Third track inside the pedal sensor worn or failed
Faulty input in the throttle actuator control module or ECM

Symptoms

  • Engine warning lamp on
  • Softer or delayed response to the pedal
  • Reduced power message on some models
