Installation Notes and Tips

Verify connector shape, terminal count, and sensor mounting location before installation. Inspect the harness connector for corrosion, bent terminals, or damaged locking tabs, and confirm the sensor seating surface is clean before fitting the replacement. Because no mounting bracket is included, reuse the original bracket only if the application requires one and the existing part is serviceable.

Quality Assurance

Prenco replacement sensors are built to match the listed electrical and physical specifications for the confirmed vehicle applications. Always confirm fitment by year, make, model, and connector style before installation.
