Installation Notes

Verify connector shape, terminal count, and throttle body mounting style before installation. This sensor uses a female oblong connector with 3 male blade terminals and is not adjustable, so correct alignment and secure mounting are important during replacement. Confirm vehicle application by year, make, and model before ordering, especially on 2002-2005 Chevrolet Cavalier and Pontiac Sunfire, 2004-2005 Chevrolet Classic, 2002-2005 Pontiac Grand Am, and 2002-2004 Oldsmobile Alero.
