Ford Repair Questions? Ask a Mechanic for Answers ASAP
Hello I will help you with your question,
The sensor is to the rear of the catalytic converter on bank 1 which is on the passenger side on this engine.
Look for any pinched or damaged wiring then remove the sensor with an Oxygen sensor socket and replace with one from the dealer or an exact fit from the autoparts store.
You can work through the right wheelhouse if you remove the wheel and splash shield.
Let me know how I can help you with this
