P2132 sets when signal F drops below its lower voltage limit. Ford uses it for the third accelerator pedal track of its second-generation electronic throttle: its 2012 OBD summary treats anything under 0.25 V as a continuity fault and lights only the wrench lamp, not the MIL. FCA's emissions recall T21 for the 2004-2006 Dodge Sprinter lists P2132 among the codes that may appear after the engine control unit is reprogrammed. GM's TACM trucks of 2004-2005 fold low readings of sensor 3 into the general code P2130. Likely causes are a short to ground on the F signal, an open 5 V feed or wear at the closed end of the track. P2133 is the high fault on F, P2122 and P2127 the low faults on tracks D and E.

Likely causes

Signal wire of track F shorted to ground
Open or weak 5 V reference to the pedal sensor
Track F worn at the rest position

Symptoms

  • Wrench or engine warning lamp on
  • Delayed or rate-limited acceleration
  • Idle may stay raised until the brake is pressed
