For the I6 engine, there is a Throttle Body Position Sensor, (TPS) attached to the actual throttle body. This cannot be removed from the throttle body itself. You need to buy the whole throttle body which includes the TPS. Just did this myself, one of the chain stores offers lifetime warranty by the way. It's very easy, turn off all HVAC inside the cab, then disconnect the battery first, very important step. Take the top resonator off, unhook the black ducting going to the air cleaner box and throttle body. Disconnect the electrical connector on top of the throttle body. Now it's just 4 easy bolts for the entire throttle body to come off. You CAN reuse the old hard plastic O-ring, no need to get another one unless it's damaged.

Where is the throttle body position sensor located at on a 2004 chevy trailblazer


On the throttle body itself. It will move with the cable.

Code P060E what does the mean on chevy trailblazer


P060e Control Module Throttle Position sensor, check all voltage and ground inputs to the ECM for an open circuit or high resistance. The computer will clear this code after three consecutive ignition cycles with no failures. Hope this helps out some.

My 2008 trailblazer is acting like it wants to die when it is idling. When I am driving its rpms run high and it starts spuddering.


Sounds like the TPS(Throttle Positioning Sensor) or the IAC(Idle Air Control) is malfunctioning. Sometimes these sensors malfunction because of a dirty throttle body. You should clean the throttle body out with throttle body cleaner first. After cleaning the throttle body out, start the vehicle. It will be slow starting and when it does start it will run rough but after a minute or two it will settle down. You will need to clear the trouble codes. Most major auto parts stores will do this for little or no charge. After clearing the trouble codes drive the vehicle. If the vehicle runs properly, no more is needed. If the vehicle still runs the same as before then continue to drive vehicle until the engine light comes back on. Read the codes and replace the defective sensor.

Trailblazer loses power. changed the o2 sensors, secondary air injection pump check valve,transmission oil an filter,an fuel filter. what other thing can be wrong


Hmm, I thought the fuel filter on 05' was on the pump in the gas tank. Must of started that in 06', mine is in the tank which sucks, my older 02' is external. Have you cleaned your throttle body? If not, likely this is your problem. We don't have a pcv system so our throttle bodies collect lots of carbon and gunk. Remember to unhook the batter while you remove the tb. 4 bolts, and you can reuse your hard gasket many times over. I like using Seafoam spray and rag to clean as it's sensor safe.

Slow shift into overdrive


No, the 2 problems are not related, the SAI pump has no function while driving. Do not "flush" your transmission unless you want problems. Just change the filter and replace fluid with Dexron 6. Many people have had tranny problems with our platform after a full "flush". Your throttle position sensor may have problems, have it checked out for the shifting issues. Remember, the TPS is attached to the throttle body, not removable. Must replace whole throttle body, IF that's your issue.

2008 trailblazer the emission light goes on and the the car shuts down when driving, it takes a few time to start again and the light is still on. I had it service 2 times andthey tell me nothing is wrong....


most likely a failed throttle body. does the light on the dash say Reduced Engine Power? If so then your throttle body has went into "forced power limited" mode. All 08 Trailblazers have electronic throttle bodies, I would see your dealer if i were you.

Throttle Problem


Well 2002 will be port injected,so the throttle body only adjust air flow.Try cleaning Mass Air Flow Sensor and replacing your fuel filter.Make sure that your air filter is clean.If you havn't had a tune up in 100,000 miles then it's time.It could be the TPS ,but would try the others first.Well hope this helps,and good luck.
