P1764 OBD Trouble Code P1764 the main thing to check is to verify the operation of the VCT solenoid. You're looking for a sticking or stuck VCt solenoid valve caused by contamination. Refer to vehicle specific repair manual to perform component tests for the VCT unit.
P1764 OBD Trouble Code Repair : The sensors receive a 5 volt reference signal from the PCM. As pressure readings change, the sensor varies the voltage and the computer reads that to determine input. In the case of a broken wire, the sensor never sees the voltage and the computer assumes a major fault. So if you get this P1764 code, first check to make sure you're getting a good 5 volt reference signal at the sensor.

Hello,

Trouble code P1756 means: Governor pressure not equal to target at 15-20 ps
Governor pressure in the trans is not correct. Fairly easy fix. Drop the trans pan and get a governor pressure solenoid from your local dealer. Bolts in pretty easy.

I hope this helps. Mike from fixya

are you sure this is the code number it is a manufacturer-specific code. and i'm not seeing it in my bood check to see if you have the right numbers on it.

The governor in the transmission maybe the problem.

Had the same code on my 2002 Jeep Grand Cherokee. Started having shifting problems as well. Code is for governor pressure sensor on trans. Cost me about $800 for dealer to fix. No problems after part changed out.

Could be a bad sensor, but it's transmission related. Anything affecting internal trans pressures should be taken care of by a reputable trans shop.
