Hi All
My check Engine light started staying on a few days ago Sad and i took my Cherry TD Sport Le straight to the main dealer in Hull to have it plugged into the DRB III. It said i had a intermittent low voltage fault on my TPS. Jeep said it was a big job an they couldnt do it and that i had to send it to a specialist garage because it was part of the fuel pump and its a T**T of a job to get it out !
Does anyone know if this is true ? Also it looks like its going to cost me at least 160 pissed to get done. There is no loss of power or any weird noises at the mo , so i dont really know how long ive got before it totally screws up ! Any help or advice would be appreciated Cheers
Steve

Steve - I would never prolong the CHECK ENGINE light for very long if you don't have to. If the vehicle is running okay for now then you may be allright, but then again no reason to chance it. I think what you should do is post a full spec list on your vehicle. What exact engine is in it and you might post some pics if you can. The more information you can give us there more likely we are to be able to help you.
I (and some other JeepHorizon members) have had similar troubles with those blasted TPS sensors.
Hope to help - CoreyXJ

hmmmm...the TPS is on the Throttle Body, not on the fuel pump. So either the shop out and out lied to you...or you are in the UK (or Europe) and have a 02 or later Cherokee. What's called 02 and up Cherokees in Europe, are called Liberty's here in the States.

If it is a Libby, let us know and we'll make sure that this thread gets moved into the Libery forum so you can get the help you need. thumbs:

According to the Haynes Manual, like it or loathe it......

Check using a high-impedance digital voltmeter, connect the positive probe to the centre terminal and the negative probe to the ground terminal (black wire). (Note: this is done by back probing the electrical connector, don't unplug the connector from the TPS).

With the ignition On, slowly move the throyyle lever until it is wide open and observe the reading on the meter. With the throttle fully closed it should read greater than 200 millivolts. With the throttle fully open, it should be a little less than 4.8 volts. If the readings are incorrect , replace.

Best of luck.

Thanks for that Carl i`ll give it a go ! Very Happy
Full Spec of my Jeep :-
XJ TD Sport LE UK 1995 on a N plate with a 2.5 Coal Burnin Lump LOL

Another question for all u other Cherry owners when im in 4H if you try to turn into a parking space at low speed it feels like the whole Jeep is going to fall apart with so much juddering and shaking Confused It is a Part Time Selectatrac and this happens on Tarmac ! Is it because of the lock being too far on or is it a common fault with them ? Sorry for all the questions but ive only had my baby 3 months and i am really chuffed with it apart from a few niggles LOL.
Just for the record I binned a 280 BHP Scooby to get my Cherry cos it cost too much to run LOL 10 mpg round town if i was lucky LOL

Don't put it in 4WD on tarmac. shock

The gear box is different to the auto Jeeps (they are designed for on road use, ours is not) and is only intended for off road where the front and rear wheels can slip in the crud, when you engage 4wd you lock the centre diff so using it on tarmac will only cause problems and wear components.

Excellent off road but the TD model is only a 4Wd vehicle when you take it off road.......it is very important that it is not in 4WD on road.

I sound like a school marm. Very Happy
