Installation Notes and Tips

Verify the lower engine sensor location before ordering, since this part is listed for that position on the supported vehicles. Confirm the connector shape, terminal count, and mounting hole layout against the original sensor before installation. Inspect the harness connector for corrosion, damaged terminals, or oil contamination before connecting the new sensor.
