P2134 targets short interruptions on signal F that are too brief or too irregular for a confirmed low or high fault. No manufacturer publishes a detection rule for it. FCA does name P2134 in emissions recall T21 for the 2004-2006 Dodge Sprinter, among the codes that may appear once the engine control unit carries the new software. GM's 2004-2005 trucks with three-track pedals handle such glitches inside P2130, whose counter adds 4 for each faulty sample every 3 ms and removes 1 for each good one until it reaches 106. Ford reports problems on F only as P2131-P2133. Look for loose pins and chafing near the pedal while moving it slowly. Effects range from a passing warning lamp to brief hesitation.

Likely causes

Loose or spread terminal at the pedal connector
Pedal harness pinched or chafed near the footwell bracket
Worn spot on track F causing momentary contact loss

Symptoms

  • Warning lamp that appears and clears
  • Short hesitation when moving the pedal
