Adding details will get you a faster solution from experts2007 Chevy Tahoe LT3 the problem I'm having is I loose half my engine power along with service traction control and stabilitrac service and it comes up with a fault code of 2165 TPS I cant believe this is the problem anybody have the same problem
Code p 2165 refers to accelerator pedal position(APP) sensor C-maximum stop performance====causes wiring--APP sensor
also refers to throttle position (TP) sensor C -maximum stop performance===causes wiring --TP sensor it is possible that you may have other problems for the traction control and stability but if the system reports a particular code then that is what you have to fix first to eliminate the possibility that it is affecting other operations
No messaage of reduced engine power ? Your vehicle has electronic throttle control . Has four position sensors , two are located in the gas pedal ,an two in the throttle body . The PCM uses these sensor to know how much to open the throttle plate ,allowing more air into the engine . How did you read this code an where did you read it's definition at ? This is not a code for your vehicle . Some time cheap code readers get them wrong .
DTC P2120: Accelerator Pedal Position (APP) Sensor 1 Circuit
DTC P2122: Accelerator Pedal Position (APP) Sensor 1 Circuit Low Voltage
DTC P2123: Accelerator Pedal Position (APP) Sensor 1 Circuit High Voltage
DTC P2125: Accelerator Pedal Position (APP) Sensor 2 Circuit
DTC P2127: Accelerator Pedal Position (APP) Sensor 2 Circuit Low Voltage
DTC P2128: Accelerator Pedal Position (APP) Sensor 2 Circuit High Voltage
DTC P2138: Accelerator Pedal Position (APP) Sensor 1-2 Correlation
DTC P1516: Throttle Actuator Control (TAC) Module Throttle Actuator Position Performance
DTC P2101: Throttle Actuator Position Performance
DTC P2119: Throttle Closed Position Performance
DTC P2176: Minimum Throttle Position Not Learned
If one of this position sensors is bad it will throw the PCM into a
Reduced Engine Power Mode
When the ECM detects a condition with the TAC system, the ECM may enter a reduced engine power mode. Reduced engine power may cause one or more of the following conditions:
• Acceleration limiting--The ECM will continue to use the accelerator pedal for throttle control; however, the vehicle acceleration is limited.
• Limited throttle mode--The ECM will continue to use the accelerator pedal for throttle control; however, the maximum throttle opening is limited.
• Throttle default mode--The ECM will turn off the throttle actuator motor and the throttle will return to the spring loaded default position.
• Forced idle mode--The ECM will perform the following actions:
- Limit engine speed to idle by positioning the throttle position, or by controlling the fuel and spark if the throttle is turned off.
- Ignore the accelerator pedal input.
• Engine shutdown mode--The ECM will disable fuel and de-energize the throttle actuator.

Hi, I'd focus just on that cylinder for now, unless the other lights come on again. This ought to give you enough information to start diagnosing the problem - http://www.obd-codes.com/p0301 - good luck!
SOURCE: transmission and traction control problems, service engine light
you may have a faulty control module
SOURCE: my 08 Chevy Uplander makes a whirring noise when
the return line on the power steering pump maybe bad are plug and it may also be low on power steering and the drive belt if the car has over 40,000 miles on it then its time to change the drive belt as well Merry Christmas & Happy New Year as always wish you the best of luck Michigan Man
SOURCE: warning light on are trac off, anti-lock, brakes, service engine
You need to have the abs system scanned for codes. You likely have a bad wheel speed sensor on one of wheels.
SOURCE: 2003 Chevy Tahoe courtesy (dome) lights do not
They don't shut off until they sit dormant for about a minute. They are set to delay as a courtesy when there is minimal light outside. **Please rate me on this answer
