Why does my Silverado say reduced engine power?
The most common reason your Chevy Silverado is experiencing reduced power is a faulty throttle position sensor. The connector, wiring harness, and sensor itself will need to be replaced to fix this issue. If this doesn't fix the issue, then it could be due to the following: Faulty Throttle Body.
How to remove throttle position sensor?
Part 1 of 2: Removing the throttle position sensor. Step 1: Locate the sensor. The throttle position sensor is mounted to the throttle body on top of the engine. Step 2: Disconnect the negative battery cable. Disconnect the negative battery cable and set it aside. Step 3: Remove the sensor electrical connector.
What is a TPS sensor?
The throttle position sensor (TPS) is used to inform the powertrain control module (PCM) of throttle position. The PCM uses this information to determine control of various output devices, such as the fuel injectors, transmission shift solenoids, etc. Basically, the throttle position sensor is a variable resistor. Its internal resistance and output signal voltage change in relation to throttle position. Some common symptoms of a failed throttle position sensor include hesitation, poor acceleration, rough idle, increased emissions and an illuminated Check Engine Light.
What is the OBD system on a 2.8L S10?
