Ford Focus Mk3 Transit Connect Mk2 Exhaust Lambda Sensor 1.5 TDCi F1F1-9Y460-DA

Ford Focus Mk3 Transit Connect Mk2 Exhaust Lambda Sensor 1.5 TDCi is an original component from the Lambda sensors and O2 sensors group, designed for precise control of the air-fuel mixture composition in the 1.5 TDCi diesel engine. Thanks to its factory origin from the Ford brand, it ensures proper cooperation with the engine control system and stable operating parameters of the powertrain.

Purpose and function in the exhaust system

The presented lambda sensor is designed for use in Ford Focus Mk3 and Ford Transit Connect Mk2 models with the 1.5 TDCi engine. This component operates in the exhaust stream, monitoring oxygen content and transmitting a signal to the engine control unit, which enables fuel dose correction, maintenance of proper injection system operation, and reduction of exhaust emissions. A properly selected lambda sensor helps maintain:

• stable idle speed and smooth acceleration,
• correct fuel consumption under typical operating conditions,
• efficient operation of the exhaust gas treatment system and compliance with the injection maps provided by the manufacturer.

Benefits of using an original Ford sensor

Using an original Ford component instead of a worn or damaged O2 sensor minimizes the risk of errors in the engine control unit and diagnostic problems. The appropriate electrical and thermal characteristics of the sensor translate into predictable powertrain behavior, which is particularly important in modern diesel engines with advanced control electronics. This component is a good choice when symptoms such as uneven engine operation, increased fuel consumption, or errors related to the exhaust control system appear. Replacing it with an original lambda sensor allows for restoring correct operating parameters without the need for interfering with the control unit software.

Product characteristics and fitment

The offered lambda sensor belongs to the Lambda sensors and O2 sensors category, which means it is a measuring element working directly with the engine control system. The product is intended for Ford vehicles and has been factory-adjusted to the specific requirements of the 1.5 TDCi unit, including operating temperature ranges and output signal parameters. Before installation, it is recommended to verify compatibility with the specific engine version and vehicle year based on the car's technical data. Proper fitment of the lambda sensor reduces the risk of premature replacement and facilitates subsequent computer diagnostics.

Condition and practical application

The product is offered in used condition, which allows for economical repair of the exhaust system while maintaining the original origin of the part. This type of solution is often chosen for vehicles used intensively, where reasonable service costs are important while maintaining compatibility with factory electronics. During installation, it is recommended to use appropriate tools for removing and installing the sensor and to check the thread in the manifold or exhaust pipe section. After replacement, it is worth performing computer diagnostics to clear stored errors and verify the operating parameters of the newly installed sensor.
