Re: 2003 Grand Cherokee Transmission issues

To get that resanator box off just wiggle up,down, left and right a little. Make sure you get the hose clamp that holds it to the throttle body good and loose. it comes off fairly easily. I had to take mine off today to change plugs. Be careful wwith the breether hose the comes off the side off it. it goes toward the rear to a tee. My tee snapped today. Its a PITA to get to.

Re: 2003 Grand Cherokee Transmission issues

Thanks for the tip on fixing the wiring. However I did find the black wire, it was actually layered against the orange/red wire, well concealed and it actually does go into the TPS, which is hard to see unless you get close because you can see bare wire if you point a light up into it at the right direction.

The hard part to see on this particular TPS is that it has 3 portals for the wires to go into, and I'm not so sure the wiring was done very professionally.

My plan was to do this. Take the Jeep into the guy who found the bad contact on my negative battery terminal and ask him to do the following.

1. do the test you recommend with the key in the ignition turned to on and measure the voltage in each wire.

2. if step one fails, then figure out what its going to take to replace all 3 wires and run them correctly.

3. If step 3 is successful, reconnect to the current TPS while I investigate the brand of TPS used as a replacement form Advance Auto Parts. The price on the invoice shows to be only $34.00, I know the Mopar TPS runs around $70.00, so maybe switchig out is food for thought also.

Hey Thumper,

thanks for your reply. Now I know what the boxes actual name is, lol.

yes I know what you mean about the extra tube that attaches to the resonator, but only because I found it hanging off the resonator one day and figured the person. working on the car at that time forgot to put it back on.

Re: 2003 Grand Cherokee Transmission issues

This link goes to PartsGeek which apparently sells the MOPAR TPS, can someone verify that this is the correct MOPAR TPS for my 2003 Grand Cherokee gas V8

03 2003 Jeep Grand Cherokee Throttle Position Sensor - Fuel Injection - Delphi, Mopar, Standard Motor Products - PartsGeek

The part I'm seeing almost suggests I need some sort of a connector piece for the wiring that should likely have been on the vehicle originally before a cheap TPS was put in its place. The one currently has 3 portals and is white and cost like 30.00 only and it looks like the 3 wires were shoved into the portals and somehow are stuck in, but I can see bare wiring also.
