Steps
Remove the intake assembly
Switch off the ignition. Remove the air-intake mounting bolts, loosen the hose clamps, and disconnect the intake hoses and electrical plugs. Lift the intake assembly clear to access the speed sensor.
Remove the old speed sensor
Unplug the speed sensor connector and remove its 12 mm retaining bolt. Pull the sensor straight out of its bore and check that the old seal is not stuck in the transmission case.
Install the replacement sensor
Inspect the new sensor seal and lightly lubricate it with the specified fluid if required. Seat the sensor in its bore, reinstall the retaining bolt, and reconnect the electrical plug securely.
Reinstall the intake and verify
Return the intake box to its mounts, reconnect the hoses and electrical plugs, and tighten the hose clamps. Start the vehicle and check for warning lights or continuing speedometer and shifting problems; scan for codes if needed.
Check your vehicle’s repair manual for exact specifications and fit.
