The throttle position sensor on my 98 Grand Cherokee was intermittent. When the cruise control was on, the transmission would sometimes downshift as if a sudden acceleration was needed, even though it was not.
The TPS is hermetically sealed, so I cut it open with a Dermal tool. The wiper inside was bent. After restoring the shape of the wiper and re-assembling the sensor with RTV sealant, it has worked perfectly since.

P0122 is TPS signal low, which could mean you have a bad TPS, or a fault in the wiring or connector. I suspect a bad Throttle Position Sensor.

My 1998 jeep grand Cherokee 4.0 engine has a idle problem. when I start the jeep it runs wide open with no control at the throttle. I Replaced the head on the vehicle.I have checked all vacuum hoses f


you need to check all sensor connections as the crank shaft sensor also will mess up your idle....try slightly unscrewing the tps and push it up or down slightly to see if this fixes the problem.

Where is the throttle positions sensor located


The Throttle Position Sensor, or TPS is connected to the throttle shaft on the throttle body.

Fig. 2: Disengage the Throttle Position Sensor (TPS) wiring harness connector

According with the Grand Cherokee Repair Manual, check this removal & installation procedure...
(see Figures 5 and 6)
  1. Remove the air intake tube at the throttle body.
  2. Disengage the TPS wiring connector and remove the two mounting screws.
  3. Carefully remove the TPS from the throttle body.
To install:
  1. The throttle shaft end has a tang that can be fitted into the TPS two different ways. Only one of the installed positions is correct. When correctly positioned, the TPS can be rotated a few degrees. To determine correct positioning, place the TPS onto the throttle body with the throttle shaft tang on one side of the TPS socket. Verify that the TPS can be rotated. If the TPS cannot be rotated, place the TPS on the throttle body with the throttle shaft tang on the other side.
  2. Tighten the two TPS mounting bolts to 60 inch lbs. (7 Nm) and engage the wiring connector.
  3. Manually operate the throttle and check for any binding.
  4. Install the air intake tube.

Hello Lubie...

I would STRONGLY recommend you get your codes read...

I TRIED ALL that TOO...

Finally my codes... said the OXYGEN SENSORS were complaining... OBD... DTC
(on-board-diagnostic... DIAGNOSTIC TROUBLE CODES)

So... of course I changed the... OXYGEN SENSORS.

The "NEW" OXYGEN SENSORS complained just as well...

I have subsequently learned the "SENSORS" are
just doing their job...

In my case reporting on a collapsed catalytic converter.
(muffler is actually a MORE common blockage).

A little hunting around... like Auto-Zone ... Napa auto...
Pep-boys... O'Reilly Auto Parts... even MIDAS might
yield FREE READINGs... (check around).

Just remember to wear your best SALES RESISTANCE...

and look up you prices on ROCKAUTO...
before you go... Hope this helps.

My 1998 Jeep Grand Cherokee Laredo turns off suddenly when stopped, and sometimes kicks when running. I'm wondering if it has to do with the fuel filter.


On my dodge truck, it was the throttle position sensor that went bad. It is located on the side of the throttle body. $50 for a new one, or $100 to have a shop do it.
