Common Problems with the Electronic Throttle Control in Volvo XC60 (2008-2017)

The electronic throttle control (ETC) system in the Volvo XC60 (First Generation) is designed to manage the air intake to the engine electronically, providing improved efficiency and performance. However, various issues can arise that affect its operation. Below are some common problems, symptoms, diagnostic steps, and repair instructions.

Common Problems
  1. Throttle Body Carbon Build-Up
  2. Faulty Throttle Position Sensor
  3. Wiring Issues or Corrosion
  4. Software Glitches
  5. Faulty Accelerator Pedal Position Sensor
1. Scan for Trouble Codes
  • Tools Required: OBD-II Scanner
  • Instructions:
    1. Connect the OBD-II scanner to the vehicle's diagnostic port, usually located under the dashboard.
    2. Turn the ignition to the "ON" position but do not start the engine.
    3. Read and record any stored trouble codes related to the throttle system.
2. Visual Inspection
  • Tools Required: Flashlight, Multimeter (optional)
  • Instructions:
    1. Inspect the throttle body and surrounding wiring for signs of damage, corrosion, or loose connections.
    2. Check the electrical connectors for the throttle body and the accelerator pedal position sensor.
    3. Look for any vacuum leaks near the throttle body.
3. Throttle Body Cleaning
  • Tools Required: Throttle body cleaner, Soft cloth, Screwdriver set
  • Instructions:
    1. Disconnect the battery to ensure safety.
    2. Remove the air intake duct to access the throttle body.
    3. Spray throttle body cleaner onto a soft cloth and clean the throttle plate and the inside of the throttle body.
    4. Reassemble and reconnect the air intake duct.
    5. Reconnect the battery and start the engine.
4. Test Throttle Position Sensor
  • Tools Required: Multimeter
  • Instructions:
    1. Disconnect the throttle body connector.
    2. Set the multimeter to the DC voltage setting.
    3. Reference the service manual for the specific voltage range for the throttle position sensor.
    4. Test the voltage at the connector while moving the throttle plate.
    5. If the readings are outside the specified range, the sensor may need replacement.
5. Check Accelerator Pedal Position Sensor
  • Tools Required: Multimeter
  • Instructions:
    1. Locate the accelerator pedal position sensor and disconnect it.
    2. With the multimeter, check the resistance across the terminals of the sensor.
    3. Compare the resistance readings to the specifications in the service manual.
    4. If the readings are inconsistent, replace the sensor.
6. Software Update
  • Tools Required: Volvo VIDA/DICE diagnostic tool
  • Instructions:
    1. Connect the VIDA/DICE tool to the vehicle and access the software update section.
    2. Follow the prompts to check for any available software updates related to the throttle control system.
    3. If updates are available, follow the instructions to complete the update.
Repair Instructions
Replacing the Throttle Body
  1. Tools Required: Socket set, Screwdriver set, Torque wrench, New throttle body
  2. Instructions:
    1. Disconnect the battery.
    2. Remove the air intake duct.
    3. Disconnect the electrical connectors from the throttle body.
    4. Unbolt the throttle body from the intake manifold.
    5. Install the new throttle body by reversing the removal steps. Ensure all connections are secure.
    6. Reconnect the battery and start the vehicle to verify that the issue is resolved.
Replacing the Accelerator Pedal Position Sensor
  1. Tools Required: Socket set, Torque wrench, New accelerator pedal position sensor
  2. Instructions:
    1. Disconnect the battery.
