P2133 is the high-voltage fault on signal F. In Ford's second-generation electronic throttle the third pedal track counts as failed once it rises above 4.75 V; the 2012 summary reports it with the wrench lamp and without MIL. FCA lists P2133 in emissions recall T21 for the 2004-2006 Dodge Sprinter among the codes that can show up after the engine computer is reflashed. GM's 2004-2005 trucks with a TACM catch excessive readings of sensor 3 above 4.38 V under the general code P2130. A track pinned near the supply would mimic a pressed pedal, so the controller drops it and works with the remaining two. Typical causes are an open sensor ground or a short to 5 V. P2132 is the low counterpart, P2123 and P2128 the high faults on D and E.

Likely causes

Open ground line of the pedal sensor

Signal wire of track F shorted to 5 V or battery voltage

Internal break in track F of the pedal sensor

Symptoms

Wrench or engine warning lamp on
Slower, limited acceleration
May appear together with high faults on other tracks if the ground is open
