2007 Chevy Silverado Throttle Position Sensor

2007 Chevy Silverado Throttle Position Sensor Location

Throttle Position Sensor Location: In the 2007 Chevy Silverado, the throttle position sensor (TPS) is housed within the throttle body. The throttle body is situated close to the intake manifold, which enables it to relay the throttle’s position directly to the engine control unit (ECU). This allows the TPS to precisely measure the position of the throttle blade as it opens and closes in response to the driver’s acceleration commands.

2007 Chevy Silverado Throttle Position Sensor Error

A throttle position sensor error on a 2007 Chevy Silverado can lead to various performance issues, as the TPS is essential for monitoring throttle position and communicating with the engine control module (ECM). Here are some common symptoms and solutions:

Symptoms:

1. Check Engine Light: The most common indicator of a TPS issue.
2. Poor Acceleration: Hesitation or sluggish response when pressing the accelerator.
3. Rough Idling: The engine may idle inconsistently or stall.
4. Jerking or Surging: The vehicle might jerk or surge unexpectedly during acceleration.
5. Reduced Fuel Efficiency: Incorrect throttle readings can lead to improper air-fuel mixture.

Solutions:

1. Test the TPS: Use a multimeter to check the sensor’s voltage output. At idle, the voltage should typically be around 0.5V and increase smoothly as the throttle opens.
2. Inspect Wiring: Check for damaged or corroded wires that could affect the TPS signal.
3. Clean the Throttle Body: A dirty throttle body can sometimes mimic TPS issues. Cleaning it might resolve the problem.
4. Replace the TPS: If the sensor is faulty or cannot be adjusted, replacing it is often the best solution.
5. Reset the ECM: After fixing the issue, clear any stored error codes by disconnecting the battery for a few minutes or using an OBD-II scanner.

2007 Chevy Silverado Throttle Position Sensor Replacement

How to replace the throttle body position sensor on a 2007-2013 Chevrolet Silverado truck? Here we provides detailed step-by-step instructions for the removal, throttle position sensor replacement, and reinstallation of the sensor. Key steps are as follow :

Removing the Throttle Body

• Remove the engine cover
• Use a trim tool to separate the hose clamp
• Use an 8mm socket to loosen the temperature sensor bolt
• Remove the hose
• Lift up and remove the hose assembly

Replacing the Throttle Body Position Sensor

• Use a trim tool or small screwdriver to pry off the sensor clips
• Open the throttle plate
• Pull the sensor straight up to remove it
• Check that the positioning tabs on the sensor are flat
• Install the new sensor and press it in
• Reinstall the sensor clips

Reinstalling the Throttle Body

• Replace the throttle body gasket
• Align the throttle body with the mounting studs and install it
• Use a torque wrench to tighten the bolts and nuts to 89 inch-pounds

Final Checks and Adjustments

• Perform an idle relearn procedure after completion
• If no scan tool is available, start the engine, let it run for 3 minutes, turn it off for 60 seconds, then start it again for 3 minutes to complete the relearn
• If idle is still not normal, do multiple deceleration tests at high speeds
• If issues persist, the vehicle may need to be taken to a dealer for reprogramming
