The 250-24464 oxygen sensor is engineered to match the exact fit and function required by BMW and Mercedes-Benz models, ensuring compatibility and reliable emissions control performance.
Technical Description and Features
This oxygen sensor features a heated design with four wires, allowing for faster sensor warm-up and improved accuracy in emissions readings. The 22 gauge wire measurement supports consistent electrical signals, while the 14.29-inch wiring harness length provides sufficient reach for proper installation. The radiused polygon male connector ensures a secure and precise fit, reducing the risk of connection issues. The sensor mounts via a threaded 18.0 mm diameter fitting, with an overall length of 17.83 inches to position the sensor correctly within the exhaust system.
Applications and Problem Resolution
- Helps maintain optimal air-fuel ratio for efficient combustion
- Reduces emissions by providing accurate oxygen level data
- Prevents engine performance issues related to faulty sensors
- Addresses check engine light triggers caused by sensor failure
- Supports proper operation of catalytic converters in BMW and Mercedes-Benz vehicles
Installation Notes and Tips
Ensure the vehicle is cool before beginning installation to avoid burns. Disconnect the battery to prevent electrical shorts. Use the correct tools to remove the old sensor and install the Walker 250-24464 oxygen sensor, threading it securely without over-tightening. Verify the radiused polygon male connector is fully seated to maintain a reliable electrical connection. After installation, clear any diagnostic trouble codes and perform a test drive to confirm proper sensor operation.
