• Service replacement after sensor contamination or heat-related failure

Installation Notes

Verify the connector shape, terminal style, and 10MM x 1.25 thread size before installation. This sensor mounts by screw-in design and uses a plug-in electrical connection, so the original harness routing and connector condition should be checked during service. Confirm the vehicle application by year, make, model, and throttle body location before ordering Standard Ignition TX266.
