The rough road sensor measures the amplitude of body vibrations and sends a signal to the controller. If the signal threshold is exceeded, the controller disables the misfire diagnostic function.
You will need a Phillips screwdriver to remove and replace the rough road sensor on your vehicle.
1. Disconnect the wire from the terminal «minus» battery.
2. Overcoming the resistance of the metal clamps, disconnect the wiring harness connector from the rough road sensor terminals.
