Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to ensure safety.
Allow the vehicle to cool down if recently driven.

2. Inspect Cruise Control Switch

Remove the steering wheel cover using a socket set and trim removal tools.
Disconnect the wiring harness from the cruise control switch.
Inspect for any signs of damage or corrosion.
Replace the switch if any issues are found.

3. Check Brake Pedal Position Switch

Locate the brake pedal position switch, typically mounted above the brake pedal arm.
Disconnect the switch and use a multimeter to check for continuity when the brake pedal is pressed.
If the switch is defective, replace it with a new one.

4. Test Throttle Position Sensor

Locate the throttle position sensor on the throttle body.
Use a multimeter to measure the voltage output while slowly opening the throttle.
Compare readings to manufacturer specifications. Replace the sensor if readings are out of range.

5. Verify Vehicle Speed Sensor (VSS)

Locate the vehicle speed sensor, usually found on the transmission.
Disconnect the VSS connector and check for proper voltage and ground using a multimeter.
If the VSS is faulty, replace it.
