Compared With the Alternatives
| MITSUBISHI dealer original sensor | Same fitment and pin pattern at aftermarket pricing, but without the dealer part number on the box unless you order branded packaging |
|---|---|
| Universal RPM sensor with adjustable mounting | The 3-pin assembly plugs straight into the MITSUBISHI loom, while a universal sensor needs a wiring adapter and may not match the P/R ratio |
| Used or reclaimed sensors | New units carry a 12 month warranty from B/L date; reclaimed stock carries none |
Use Guide
- Confirm the vehicle is a 12V system before fitting
- Match the 3-pin connector against the old sensor before ordering
- Isolate the battery, unplug the failed sensor from the transmission or engine block and fit the replacement in the same orientation
- Test the tachometer reading at idle and under load before releasing the vehicle
- If the tachometer still reads zero, check the wiring harness and ECU signal input before condemning the sensor
