Frequently asked questions

What does the ETC6660 stepper motor do on the V8 EFI engine?

The ETC6660 stepper motor is the idle air control valve on the V8 EFI petrol engine. It meters the air bypassing the throttle plate so the ECU can regulate idle speed. It's fitted to the Discovery 1 and Range Rover Classic with multi-point injection.

Where is the stepper motor located?

It's mounted on the plenum chamber of the V8 multi-point injection system, controlling the air that bypasses the throttle plate. On the Discovery 1 and Range Rover Classic V8 EFI it sits on top of the intake plenum, wired to the engine ECU.

What are the symptoms of a failing stepper motor?

A failing stepper motor typically shows as an unstable or hunting idle, stalling at rest, or a high idle that won't settle. Because idle is ECU-controlled on the V8 EFI system, these idle faults usually point to the idle air control valve or its wiring.

Which Land Rovers does the ETC6660 fit?

It fits the V8 EFI petrol Discovery 1 (VIN FA393361 to WA799999) and Range Rover Classic (1986-1991 to VIN HA610293, 1992-1994 from VIN JA610294). Use your VIN to confirm, as it suits multi-point injection V8s only.
