Frequently asked questions

What does the ERR4352 stepper motor do?
The ERR4352 stepper motor acts as the idle air control valve on the V8 EFI petrol engine. It meters air bypassing the throttle plate so the engine management ECU can regulate idle speed under varying load and temperature, mounted on the intake plenum.
Which Land Rover models use this V8 EFI stepper motor?
This stepper motor fits the V8 EFI petrol Defender, Discovery 1, Discovery 2, Range Rover Classic and Range Rover P38. On the Discovery 1 NAS it applies from VIN TA163100. Confirm your car runs the multi-point EFI V8 before ordering.
What are the signs of a failing idle air control 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. On the V8 EFI these symptoms usually appear when the motor sticks or the pintle carbons up. Idle problems can also stem from vacuum leaks.
