2004 Ford Focus Transmission Electrical Parts

Relays are electrical switches used to convert a small electrical load into a circuit capable of handling a high amperage load. Computers and small switches are not designed to carry the higher amperage requirement of a circuit that may have an electric motor, solenoid, or high amperage lighting fixture. Within a relay are contacts that are controlled with electromagnetism, when the circuit switch commands the device on or off, magnetism will pull or release the contact arm closing or opening the contacts within the relay that carry the voltage.

The Automatic Transmission Fluid Temperature Sensor provides an input to the transmission control module as to the operating temperature of the automatic transmission fluid under the many operating conditions. The transmission control module will provide the transmission hydraulic circuits the optimal fluid pressure for current temperature conditions.

Modern vehicles may have 100 or more electrical harness connectors in every operating system of the vehicle. Terminal tension may weaken with time or corrosion may occur within the connector housing making replacement necessary. When replacing any harness-connector assembly approved wire termination methods must be followed to ensure a successful and long-term solution to the original problem is made. A failed terminal connection, terminal corrosion or damaged wire will result in an electrical system fault.

The Motorcraft Speed Sensor Assembly is the transmission-mounted induction coil that creates an electrical signal as the teeth of an internal rotating transmission ring/gear spin past it.

The only parts recommended by Ford Motor Company for Ford, Lincoln and Mercury vehicles.

The ABS or Anti-Lock Brake System ECU monitors the Wheel Speed Sensors rotational speed for anti-lock brake function, stability control and traction control. The ABS sensors report the speed of all four wheels to the ECU to determine if the wheels are locking up and to help provide safer stopping. Reasons for replacement include: ABS/brake lamp illumination, no or erratic ABS operation or problems with stability and or traction control systems.
