General Maintenance Precautions
Sensor Matching: Some models (e.g. F-150) require ECU adaptive learning with Ford IDS tool after replacement.
Installation torque: Strictly according to the manual standard (usually 30-40N・m), to avoid over-tightening damage to the ceramic probe.
Cleaning agent selection: prohibit the use of cleaning agents containing silicon to prevent sensor poisoning.
Wiring harness inspection: Focus on checking the sensor plug for oxidation or corrosion.

Supplemental Data Note: The above data is based on Ford official repair manuals and industry standards.
The above data is based on Ford's official repair manual and industry standards, and the actual repair should be combined with the vehicle's VIN code to check the specific configuration.
Part Number Adaptability: Some part numbers may be slightly adjusted due to differences in engines' models and years, so it is recommended to check the specific adaptability information through the VIN code.

Fault Code Diagnosis:Oxygen sensor failure may be related to the ECU software version, it is recommended to use a special diagnostic instrument for parameter calibration.
(Note: The above prices may fluctuate ±15% due to regional channel differences, real-time data suggest checking local dealers)
