Replace your failed engine computer with an OEM 2005 Toyota Corolla 1.8L ECM (also called a PCM or ECU), programmed to your vehicle before it ships.

This module is a direct replacement for units carrying service number 89661-02C50. Every unit is refurbished, bench-tested against OEM specification, and flashed with the latest manufacturer software.

Match your service number exactly

Toyota engine computers must match precisely. A module with a different suffix will not work correctly, even on the same year and engine. Read the number from the label on your existing module and check it against the one above, or send us your VIN and we will identify the correct unit before anything ships.

Check build location and emissions

Toyota modules differ between US-built and Japan-built vehicles, and between Federal and California emissions. The eighth character of your VIN and the emissions sticker under the bonnet identify which you have.

Why Toyota modules must be programmed

These vehicles use an immobiliser. The engine computer, keys and immobiliser have to be registered to each other or the engine will crank without starting. Several sellers supply these units unprogrammed, which means a locksmith or dealer visit before the car will run. We programme yours to your VIN before dispatch.

No core charge, and no core to send back

There is no core charge on this module, no deposit and nothing to return. Keep your old unit, and your lifetime warranty starts the day it ships.
