Can any one please tell me where exactly they are located in 2003 Chevy Silverado 5.3 V8

    The Accelerator Pedal Sensor is not serviceable as it's a part of the accelerator pedal assembly and has to be replaced as a unit.

    The same thing with the Throttle Position Sensor to the Throttle Body assembly. But depends on the production (VIN): Some early VIN is serviceable and can be replaced individually from the throttle body unit. See the attachment.

    1- Remove the air cleaner outlet resonator. Refer to Air Cleaner Outlet Resonator Replacement .

    2- Disconnect the throttle position (TP) sensor electrical connector and remove the TP sensor (Two screws)

    3- The TP sensor is an electrical component. Do not soak the TP sensor in any liquid cleaner or solvent, as damage may result.

    4- To install is in reverse of removal.

    5- Clear all of the DTC and adaptations and do the idle relearn. If not, you'll have idle problem or the engine will run like crap.

    The throttle position sensor is not serviceable, it is part of the throttle body assembly and motor. If it truly is bad you will need to replace the assembly.
