Motorcraft Oxygen Sensors are engineered to provide original equipment performance and reliability. All Motorcraft Oxygen Sensor designs undergo rigorous lab and real world tests in order to meet Ford engineering standards.

Features & Benefits:

• Motorcraft Sensors must pass, depending on application, durability tests for thermal cycling and shock, vibration, humidity, and corrosion.
• Electrical tests measures sensor output across a wide range of simulated operating conditions as well as for electrical interference.
• Functional tests helps ensure sensors perform as designed and send accurate signals to ECM.
• Mechanical testing replicates typical handling and installation procedures.
• Sealed sensors use OE connectors for sure and accurate fit. Consolidated single wire length with a no key connector allows for easy installation and coverage for multiple applications.
• Sensor is the same as when the vehicle was produced, designed to strict tolerances to help minimize false check engine lights.
• Protective sleeve helps shield wire leads from heat and pre lubricated with anti seize compound for easy installation.

Engine Bank Identification

An OBD SCAN TOOL will usually identify Oxygen (O2) Sensors by the Bank Number (B1 = Bank 1; B2 = Bank 2) and Sensor Number (S1 = Sensor 1; S2 = Sensor 2, etc.). Bank 1 is not on the same side of the engine for every vehicle.

Bank 1 will always contain Cylinder 1. To locate Cylinder 1, Check for cylinder labels on spark plug wires Look for the cylinder that is closest to the front of the engine Refer to your Repair Manual (Found under 'Literature') Bank 2 refers to the bank opposite Bank 1 Sensor 1 refers to the sensor before the catalytic converter Other Common Terms: Upstream Sensor, Pre-Cat Sensor Sensor 2+ typically refers to the sensor(s) after the catalytic converter Other Common Terms: Downstream Sensor, Post-Cat Sensor
