Installation Notes and Tips

Verify the connector shape, terminal count, and wire quantity before installation. This part uses a 3-pin female oval connector with male terminals, so matching the harness connection is important for proper fitment. Confirm the vehicle application and position listed for your exact model year before replacing the sensor.

For best results, inspect the connector, wiring, and surrounding engine components for damage or contamination before installation. On vehicles with intake-position applications, confirm the intake location matches the catalog listing.
