DTC P1651: Power Steering Pressure (PSP) Switch Input

WARNING: This page does not describe the selected car, but rather 30 other vehicles, including the 2006 Mercury Mountaineer, 2006 Mercury Monterey, 2006 Mercury Montego, 2006 Mercury Mariner, and 2006 Mercury Grand Marquis. However, it is still accessible from the selected car via links, so may be relevant.
P1651 - POWER STEERING PRESSURE (PSP) SWITCH INPUT

Description:  The powertrain control module (PCM) counts the number of vehicle speed transitions from 0 to a calibrated speed. After a calibrated number of speed transitions, the PCM expects the PSP input to change. This DTC is set if the transition is not detected.
Possible Causes: 
  • Vehicle towed with the engine running
  • The power steering hydraulic concern was repaired but the DTC was not erased
  • PSP switch/shorting bar damaged
  • SIG RTN circuit open
  • PSP circuit open or shorted to SIGRTN
Diagnostic Aids:  Check if the vehicle was towed or a power steering repair was carried out.
Observe the PSP V PID while checking the wires for intermittent concerns.
