2001 jeep grand cherokee transmission revving-codes p1757, p1762

I had my car checked and the dignostics said I needed a new pressure switch in my transmission, and we changed that but it still is not going into gear and the engine makes a loud revving sound, like it is getting stuck from gear to gear, or that it skips a gear. We checked the fluid and the pan was good- no metal shavings..and now it continues to do the same thing but is driveable, a new code P1757 AND P1762 came up- can anyone help me who knows what those codes mean?

What does codes p1757 an p1762 on 2001 grand cherokee mean


P1757 - Governor Pressure Above 3 PSI When Request Is 0 PSI

P1762 - Governor Pressure Sensor Offset Improper Voltage

Both codes are refered at the governor pressure sensor; I am 99% certain that is bad. Just replace it. Check the voltage on the Light Green/White wire at pin 29 in the white PCM connector with key ON, engine OFF (KOEO). It should be about 0.5-0.7 volts.

If higher than 0.8 volts, check the Transmission Temperature sensor reading on a scan tool. If the Transmission Temperature sensor reads normal, the sensor ground is OK. If the sensor ground is OK, then replace the Governor Pressure sensor.

Hope this helps.

I have a code p1762 for my 97 jeep grand cherokee


Trouble code P1762 means: Governor pressure sensor offset improper voltage. Gov. Pressure Sensor.It is located in the valve body of the transmission and requires dropping the transmission pan to replace. Sounds much more difficult than it is. Since you have to change your fluid it's a good idea to change the trans. filter .

I have a ODB II code reader giving p1763, p1762, p0303


Your right about the two codes. It's really a transmission part.
As soon as you open up the transmission pan, it right there.

As for PO303, that is a missfire in cylinder #3

I hope I answered your question.

Transmission problem


I had a shifting problem. The car would start in the wrong gear and shift at wrong times. I repaced the governor postion sensor and tranny fluid and the problem has been fixed for several years. Did you replace the tranny fluid?

Check engien lihgt with code p1762


CEL Code P1762 is Governor Pressure Sensor Offset Improper Voltage. Make sure all your wires going to the sensor are ok, then if they are I would look into a new Sensor. Hope this gives you some direction. Thanks for Using FixYa!
