Replacement ECU

The Replacement ECU (Engine Control Unit) monitors the emission system, timing and other functions of the engine. It is located underneath the car's dashboard, behind the glove compartment. Its purpose is to collect information from sensors and to provide the best mileage with lowest emissions. It receives signals from the sensors of various devices, interprets the values and readings using a look-up table and adjusts the engine actuators accordingly.

The engine control unit analyzes the readings taken from various devices and deciphers the intervals for the scheduled maintenance. If there is any problem inside the drive train, the control unit detects it and sends a message to the operator. The ECU controls the idle speed and maintains the speed set with the help of a cruise control. If you find that your car's ECU is not functioning properly, you should replace it as quickly as possible to avoid further damage. At Buy Auto Parts we stock a wide range of replacement ECUs at unbeatable prices. We provide free shipping on all orders above US $50.
