If my throttle potion sensor is bad on my 2007 chevy tahoe over time can that cause my transmission to go?


I doubt it.
The sensor could make the transmission not know when to shift, but not much else.

It sounds like you have a vacuum leak somewhere. Take a propane torch, turn on the gas but DON'T LIGHT IT!!! Start the vehicle and point the torch at any and all vacuum outlets and hoses. If the engine revs up slightly, you have found your leak. The vacuum will pull the propane into the engine causing it to rev. Check the throttle body mounting plate good and vacuum lines at the back of the engine and transmission. Hope this helps.

My 1998 buick park ave jerks when i press on the gas,the car has 85,000 mils,i have had my fuel pump changed and a sensor changed,but it stills jerks when i press on the gas,plus it stopped on me 3 times...


That sounds like a misfire. Change the spark plugs, your best value for those as opposed to the expensive ones listed in the manual are Autolite 105's. Get the copper core model and gap them to .060"
Also clean thoroughly or change your air filter and clean the throttle body. Also clean the MAF ( mass airflow sensor). That sensor is easiest to identify on your engine as the largest sensor and it is mounted into the top of the throttle body with two security type screws. If it is the original sensor it will also be labeled on the top with "ABC". Carefully remove the sensor by unplugging the wiring harness, loosen the security type screws and pull straight up. There will be an o-ring type grommet in the sensor mounting hole or it may still be attached to the sensor itself; don't lose it. It prevents air flow leaks.
To clean the sensor, look down inside the "shaft" part of the sensor. You will see two diodes. DON'T touch them. DON'T drop the sensor, or tap on it.
Use isopropyl alcohol that you can find in your local health&beauty department store sections, the 70% formula will work well. There's no necessity for special potion type expensive sprays or whatever that's on the market for cleaning your MAF.
Simply pour some of the alcohol over the sensor diodes and let it sit for a few minutes to dry. The diodes are clean when they look shiny. That is optimal and it getting dirty is commonly over looked on your particular car...cleaning it often does make very noticeable improvement.
Then it is ready to reinstall. Screw the it in by alternating between each one so that it mounts flat onto the throttle body; you don't want it to be able to leak any incoming air. Then before plugging the sensor wiring harness back in, now would be a good time to clean any corrosion or crud from the plug. You can use the same alcohol as before; pour on and let dry.

Throttle position switch. how much for the part? is it easy to repllace?


This sensor sends the ECU an output signal which corresponds to the opening of the throttle valve. Using this output signal, the ECU precisely controls the air/fuel ratio during acceleration, deceleration and idling. The TP sensor and the throttle switch are combined as part of an assembly. The switch signal turns ON only when the throttle is opened to the idle position or at Wide Open Throttle (WOT) acceleration.

REMOVAL & INSTALLATION

Fig. 5: Lift off the throttle position sensor
  1. Disconnect the negative battery cable.
  2. Disconnect the throttle sensor electrical harness.
  3. Place a matchmark on the throttle position sensor and throttle body mounting surface, so that during installation, the sensor can be properly aligned.
  4. Remove the 2 screws securing the throttle sensor to the throttle body assembly.
  5. Remove the throttle sensor by pulling it in the axial direction of the throttle shaft.
  6. Remove the throttle sensor O-ring and discard.
To install:
  1. Using a new throttle O-ring, install the throttle sensor, aligning the matchmarks. Install and hand-tighten the retainer screw.
  2. Connect the throttle sensor electrical harness.
  3. Connect the negative battery cable.

Hope this help (remember rated and comment this). Good luck.
