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.

2001 grand cherokee idles funny

Hi there, do you get water from the air conditioning unit entering the passenger foot well, if so then perhaps water is dripping onto the electrics below and causing these problems (blocked evaporator unit) alternatively, get jeep to reset your system (2 minute job) and this should work, keep an eye on it as the first new code that appears should be the problem area, hope this helps

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.

Grand Cherokee laredo P1763 and P1762

It's a transmission related problem, that you should have looked at a.s.a.p. to avoid costly transmission repairs down the road. Have it scanned at a reputable transmission repair place, dealer, or mechanic you trust. The drain pan will have to come off to perform repair, so have a transmission service (filter & fluid) done while your at it, unless it was done recently.
