Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a flat surface and the ignition is off.
Disconnect the battery to avoid electrical shorts.

2. Inspect and Replace Wheel Speed Sensors

Locate the wheel speed sensors on each wheel hub.
Remove the sensor wiring harness and the mounting bolt.
Inspect the sensor for damage or dirt; clean or replace as necessary.
Reinstall the new or cleaned sensor and securely fasten it with the bolt.

3. Check and Replace Throttle Position Sensor (if needed)

Disconnect the throttle position sensor's electrical connector.
Remove the mounting screws and take out the sensor.
Test the new sensor with a multimeter to ensure it meets specifications.
Install the new sensor, reconnect the harness, and ensure it’s securely mounted.

4. Inspect ABS Module

Locate the ABS module in the engine bay or under the vehicle.
Check for any fluid leaks or visible damage.
If necessary, replace the ABS module by disconnecting the wiring harness and mounting bolts, then install the new module and reconnect the harness.
