Detailed Product Description
This Walker Products Aftermarket oxygen sensor (part number 350-33014) is engineered to meet the exact specifications of various Ford, Lincoln, Mazda, and Mercury models such as the Ford Bronco, Lincoln Town Car, and Mazda B2300. The heated sensor element allows for quicker activation, improving fuel efficiency and reducing emissions shortly after engine start. The sensor features a threaded mounting type with an 18.0 mm diameter, ensuring a secure and precise fit. Its wiring harness length of 8.39 inches and 3-wire configuration with 20 gauge wire provide reliable electrical connectivity. The radiused polygon male connector is designed for a firm and accurate connection to the vehicleโs wiring harness, minimizing the risk of disconnection or signal loss.
Common Applications and Issues Addressed
- Helps maintain proper air-fuel ratio for efficient combustion
- Reduces engine misfires and rough idling
- Prevents increased emissions and failed emissions tests
- Improves fuel economy by providing accurate sensor data
- Resolves check engine light triggers related to oxygen sensor faults
Installation Notes and Tips
- Ensure vehicle compatibility with the specific fitment list before installation
- Use appropriate tools to avoid damaging the 18.0 mm threaded sensor
- Disconnect the battery before sensor replacement to prevent electrical shorts
- Verify connector orientation; the radiused polygon male connector must align correctly
