Question about Jeep 2004 Grand Cherokee Laredo

Error code P1763

My Jeep had been idling too high, and would overheat if sitting still for very long. Friday evening, coming home from work it began misfiring?, RPM gauge would rise and drop with no acceleration at all, sputter, etc. We got the idle air control valve replaced & throttle cleaned. Now idle problem, and overheating while sitting seems to have stopped but the RPM gauge is still jumping up and down, POOR acceleration, and the gpm have dropped drastically according to the read out. Stopped at Auto Zone they hooked up and received the P1763 code. Any help would be appreciated, this is my transportation to work and I need to know what this means.

Http://www.jeepforum.com/forum/f13/p1763-code-174927/ forinstance this guy needs to replace both the sensor and the solenoid
and perhaps mod it like the dodge guys have done

its a bad governor pressure sensor

looking here you'll find the issue
and checking out this error its common to dodge also
there is also other mods to the transmission to stop it happening

{you need to paste this into the browser}
but this is the error

you replace it and clear the code

Testimonial: "Thank you for the information will check into replacing the governor sensor and solenoid. Worth a try. I've had to make arrangements for other transportation for tomorrow for work, hopefully if the sensor(s) and the solenoid are replaced, my transportation to work will run."

    Thank you, got the governor pressure sensor and solenoid. And so far, so good. Still alittle doggy on take off, but think that may be due to spark plugs. Will try to replace with new boots? Unless there is something else you feel it could be. One shop told us that cylinders 1 & 3 weak.

  • Anonymous Apr 23, 2015

    weak cylinders ???? do you mean the compression if so this isnt a good thing ,,,!! if its not then your prob right and its the plugs use 4 electrode types and also this could be a bad 'coil pack' so you need to get the garage to measure the EHT at each plug see if 1/3 are a lower voltage...

    in this type of car it could be a couple of worn valve seats and this means the head needs to come off and the valves tested for a good seal and reground or replaced usually something worn or chipped as the engine isnt so old i dought its the pistons sealing rings

    you should get a printout of the engine done in the uk there is lots of tune up centers they can give you a print out take a pic of it jpg like 300K in size and post it up lets see what the numbers say

    another thing i thought of was to replace the air and fuel filters...

  • Anonymous Apr 23, 2015

    with all the dust around they will get badly contaminated also i see chili volcano goes off so even more dust use some REDEX cleaner ,, it will de coke the engine here is an ebay link to the stuff you can source it local http://www.ebay.co.uk/sch/i.html?_from=R... bad valve seating can be caused by coke build up if forinstance a cylinder starts to go down then others follow its strange its 1 and 3 ..

  • Anonymous Apr 23, 2015

    what you find is one problem is related in maths to another so if the spark plugs arent so good the engine gets coked up and bad fuel filter slows the fuel esp on take off a bad air filter wont help and will make the engine run rich so this also burns the plugs and etc so its a vicious circle

Overheating when I sit idle.


Over heating the engine is a serious concern. With the hood raised you should hear the motorized fan turn on just behind the radiator as the engine requires additional cooling.. If you look in from the rear of the radiator you should see the fan blades.

This electric powered motor operates on a thermostat and when the engine temperature rises this fan should come on. I'm assuming from your description that when driving and air is flowing through the radiator as the car travels the engine is nor overheating.

Check fan motor thermostat, check fan motor and check wiring.

Hi, our oce variolink 2822c suddenly began to show; "malfunction detected. inform the service representative of the error code", trouble code: c- 3721. Unfortunately service representatives...


Your machine is made by Konica Minolta. The C3721 code means that your fuser unit has detected an overheat condition. The fuser unit is the assembly that uses heat and pressure to "fuse" the loose toner onto the paper. It is located right where the copies exit the machine. Your are going to need to have your local service company come out and make repairs. You may get advice as to how to reset the code but beware. Since this is an overheat code, if you reset it more than once you can do severe damage to your fuser unit. You may turn a simple and relatively in-expensive repair into a major one.
I would waot if at all possible for the service technician, but I have only worked on Konica Minolta copiers for nearly 28 years now.
Good Luck and Thank You for using Fixya.

2003 Grand Cherokee Overheating


This might help you as it looks as though you have an electric fan to cool , there should be a sensor on your radiator hoses upper and lower.they are actually switches triggered by the coolant temperature in side the hose. While your Jeep is sitting idle, shut off the AC as it adds to the heat off the engine not to merntion useing more gas. you should make sure both high and low speeds on the coolant fan work. good luck if this does'nt help check out the post, with more, on the 1995 Jeep heating up..

Will idle high sometimes up to 3000 rpms when driving or sitting still


I have the same Jeep and same problem. The engine was running rough. The Jeep dealer fixed a vacum problem in the manifold and they then decarbonized and cleaned the fuel injectors. After these repairs the idle problem began, it would spike to 2000 rpm while sitting at idle, sometimes it would slowly come down, sometimes I would have to tap the accelerator. I took it back in and they then replaced the throttle motor and reprogrammed the PCM (Power Control Module?) Still same problem. Now they suspect a another vacuum leak and I am taking it back in on Tuesday, will let you know what happens, $ 1,300 so far.

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.

This means your thermostat is bad. Needs to be replaced. Also do coolant flush.
