P1650 - Power Steering Pressure (PSP) Switch Malfunction In Key On, Engine Off Self-Test, this DTC indicates the PSP input to the PCM is high. In Key On, Engine Running Self-Test, this DTC indicates that the PSP input did not change state. Steering wheel must be turned during Key On, Engine Running Self-Test
PSP switch/shorting bar damaged
SIG RTN circuit open
PSP circuit open or shorted to SIGRTN
PCM damaged.

P1651 - Power Steering Pressure (PSP) Switch Signal Malfunction The PCM counts the number of times vehicle speed transitions from 0 to a calibratable speed. After a calibratable number of speed transitions the PCM expects that the PSP input should have changed. This DTC is set if the transition is not detected. Vehicle towed with engine running
Power steering hydraulic concern was repaired but DTC was not erased
PSP switch/shorting bar damaged
SIG RTN circuit open
PSP circuit open or shorted to SIGRTN
PCM damaged
Check, if possible, if vehicle was towed or power steering service was performed.
Observe PSP V PID while checking wires for intermittents.

P1703 - Brake Switch Out of Self-Test Range Indicates that during Key On Engine Off (KOEO) Self-Test, BPP signal was high. Or during Key On Engine Running (KOER) Self -Test, the BPP signal did not cycle high and low. Open or short in (BPP) circuit
Open or short in stoplamp circuits
Damaged PCM
Malfunction in module(s) connected to BPP circuit (Rear Electronic Module [REM] Windstar and LS6/LS8 and Lighting Control Module (LCM) Continental and Town Car)
Damaged Brake Switch
Misadjusted Brake Switch
Check for proper function of stoplamps. Follow correct Self-Test procedures, refer to Section 2, Quick Test .

P1705 - Transmission Range Sensor Out of Self-Test Range

P1709 - Park/Neutral Position Switch Out of Self-Test Range The DTCs indicate that the voltage is high when it should be low. PNP/CPP circuit short to PWR
Damaged PNP or CPP switch
PNP/CPP circuit open in the SIGRTN
Damaged PCM
When exercising either the PNP or CPP switch the voltage should cycle from 5.0V to low

P1729 - 4x4L Switch Malfunction The 4x4L switch is an ON/OFF. If the PCM does not see low voltage when the switch is ON a DTC will set. 4x4L harness open or shorted
Damaged electronic shift module
Damaged PCM
Verify the 4x4L switch cycles ON/OFF.

P1780 - Transmission Control Switch Out of Self-Test Range During KOER self-test the TCS has to be cycled, if not cycled a DTC is set. TCS circuit short or open
Damaged TCS switch
Damaged PCM
Verify the TCS switch cycles ON/OFF

P1781 - 4x4L Switch Out of Self-Test Range The 4x4L switch is an ON/OFF. If the PCM does not see low voltage when the switch is on a DTC will set. 4x4L harness open or shorted
Damaged electronic shift module
Damaged PCM
Verify the 4x4L switch cycles ON/OFF

P1900 - Output Shaft Speed sensor circuit intermittent failure See DTC P0723

P2195 - STALL AT IDLE AFTER A COLD START
