Installation Notes

Verify the connector style, terminal count, and sensor position before installation. AU0179 uses a rectangular female connector with two terminals and no included wiring harness, so the existing harness and connector condition should be checked during service. Confirm whether the vehicle calls for an output or input sensor location, especially on 2006 Lincoln Town Car applications where both positions are listed.

Quality Assurance

NTK technical sensors are tested under demanding conditions, including thermal shock, vibration, and OBD verification, to support OE-level fit and function. The AU0179 is engineered to meet or exceed OE specifications for the listed Ford, Lincoln, and Mercury vehicles.
