It really would depend on wether you know what is in it and what type of vehicle it is on. If it's an object that you can see but can't get pliers or your hand to then I would strongly recommend taking the throttle body off and hold it upside down and play with the linkages until it falls out.

Replaceing trottle cable


Take the cable end off the throttle body. You may have to remove the cruise cable first. Then remove the screws for the throttle cable bracket. Note how the cable is routed past hoses and obstructions to reach the throttle body. Now inside the car, remove the cable from the accelerator pedal, push the rubber grommet at the firewall out towards the engine, and remove the cable out the engine side. Reverse procedure to attach new throttle cable.

I got codes P 2104 & P 2112 - what is this and how can it be sloved?


P2104 - Throttle Actuator Control (TAC) System - Forced Idle
P2112 - Throttle Actuator Control (TAC) System - Stuck Closed.
P2104 was set because the pcm had to step in to set the idle. The TAC system is in the failure mode effects management (FMEM) mode of forced idle. P2104 is just an informative code, set because of P2112. P2112 possible causes: Binding throttle body, stuck closed or
Damaged PCM

tell your dealer technician to follow pinpoint test DV1 in the workshop manual. (but also to reference test QE1) DV1 deals with him/her checking the throttle position voltages, if these voltages are not within spec, proceeding with checking for obstructions in the throttle body, then if this passes, he/she checks the wiring to the TAC assembly. there are many steps in this test and since the truck isnt here i can't tell you where the test will go (throttle body assembly, PCM, etc.) most likely it will be the throttle position sensor which is a part of the throttle body assembly or a simple connector coming unplugged or wiring being cut, but once again since i dont have the truck in front of me i can't be 100% sure. good luck. hope this helps.

WHERE IS THE THROTTLE POSITION SENSOR ON A 1999 ALERO


b693539.jpg Bolted to the side of the throttle body.

CLICK HERE to see a generic picture with the sensor mounted on the right side.

Theres a black plastic "box" above the throttle assembly...
Remove that to get to the throttle position sensor underneath.
If you can locate the two wires that control the throttle assembly...then the throttle position sensor is on the other side of the throttle assembly. Remove the large tube that goes from the air filter to the black plastic "box" above the throttle assembly.
Also disconnected anything else connected to that black plastic "box". Then pull "box" up and right there on the left side of the throttle assembly is the throttle assembly sensor.
