Installation Notes

Verify connector style, terminal count, and application before installation. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application. Confirm the sensor mounting location and reuse only serviceable surrounding components as needed. For best results, inspect the intake tract for leaks or contamination before replacing the sensor.
