GRAND CHEROKEE GOVERNOR PRESSURE SENSOR

2001 All Other Makes All Other Models

2001 Grand Cherokee 4.0L automatic. The check engine light is on and the ODB-II codes that it produced are as follows.

P0121 (M) - Throttle/Pedal Position Sensor/Switch A Circuit Range/Performance Problem
TPS signal does not correlate to MAP sensor signal.

P0121 (M) - Accelerator Position Sensor (APPS)
APPS voltage input below the minimum acceptable voltage.

P1757 - GOV Press Not Equal to Target @ 15-20 PSI
The requested pressure and the actual pressure are not within a tolerance band for the Governor Control System which is used to regulate governor pressure to control shifts for 1st 2nd and 3rd gear (Zero Pressure Malfunction).

P1762 (M) - Governor Pressure Sensor Offset Volts Too Low or High
Sensor input greater or less than calibration for 3 consecutive Neutral/Park occurrences (4-speed auto. Trans. Only).

I replaced the TPS but I'm still having the problem of the governor pressure to control shifts for 1st 2nd and 3rd gear (Zero Pressure Malfunction). Does anyone have any instructions on how to locate and replace the Govenor Pressure Sensor? As a side note and I guess most importantly, could this be my problem? Thank you in advance for your assistance.
