Throttle position sensor on jeep cherokee - 2002 Jeep Grand Cherokee

On the throttle. Under the hood, you will see the air filter plenum going to the throttle. On the throttle you will see cables coming from the firewall connecting to the throttle linkage. Just opposite of that linkage is the throttle position sensor(TPS). two screws/bolts hold it on.

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

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.

to me it sounds like the crankshaft position sensor is out of range, move it a little closer and try to start it again..

TPS is on the rear of the throttle body the throttle shaft that is attached to the gas pedal cable passes through the TB and goes directly into the TPS.

check the fuel pressure on the fuel pump

code refers to throttle cable adjustment, throttle position sensor, throttle position switch,throttle pedal position sensor, throttle position position switch, this is the areas that you need to check out

Take the Intake Air Hose off. This goes from the Air Filter to the Throttle Housing. When you see the Throttle Gate draw a horizontal line across the center - this should be the the Throttle Gate Pivot Arm. The Throttle Position Sensor is lined up with this Pivot Arm. It should be the only sensor lined-up with this. There should be a Idle Air Sensor that is located above this, but this is not lined-up to the Throttle Gate Pivot Arm.
Let me know if this helped, or if you have additional information or questions. Feel free to contact me on FixYa.com!

the throttle position sensor is located on the side of the throttle body even with the throttle plate.

Sensor is attached with two torx screws on the throttle body. it is easily removed and is non adjustable. Be sure you engage the throttle plate shaft properly before tightening it up if unsure what it looks like, buy the new one first..
