P1651 - Power Steering Pressure (PSP) Switch Signal Malfunction

WARNING: This page does not describe the selected car, but rather 30 other vehicles, including the 2004 Mercury Sable, 2004 Mercury Mountaineer, 2004 Mercury Monterey, 2004 Mercury Marauder, and 2004 Mercury Grand Marquis.

P1651 - POWER STEERING PRESSURE (PSP) SWITCH SIGNAL MALFUNCTION

Description:  The 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.
  • PCM damaged.
Diagnostic Aids: 
  • Check, if possible, if the vehicle was towed or power steering repair was performed.
  • Observe the PSP V PID while checking the wires for intermittents.
