About this part

This NTK sensor reads the speed of the transmission output and reports it to the vehicle's control units. The ECU, TCU or PCM uses that signal to set shift points, ignition timing and the air and fuel ratio. A failing output sensor can bring harsh or erratic shifts, a dead speedometer or a warning light. NGK says the sensor is built to meet or exceed original fit, form and function for accurate transmission speed monitoring.

Fitment notes

Part AU0151 has a single catalog row: the 1997 Honda Civic with an automatic transmission. The sensor is the output unit located on the transmission case, so do not confuse it with an input or wheel speed sensor. Check that your Civic has the automatic gearbox and compare the old sensor's location. Verify your trim in the table above or send your VIN before ordering.

Installation notes

Clean dirt from around the sensor before removal so nothing falls into the case. Inspect the connector and O-ring, and top up transmission fluid if any is lost. Clear stored codes afterward and road test to confirm shifting and speedometer readings.
