Installation Notes and Tips

Verify connector shape, terminal count, and mounting style before installation. This sensor uses a 1-hole mounting design and a 2-pin electrical connection; some listed applications note sensor-only service or specific connector details, so compare the original part to the vehicle harness and mounting point before replacement. Clear diagnostic trouble codes after installation and confirm proper engine start and idle quality.
