LH-SFI Control Module Self-Adaptation

LH-SFI Control Module Self-Adaptation

A self-adaptation feature for the emission control system is incorporated into the LH-SFI control module.

The LH-SFI control module conducts a self-adaptation process whereby the correction factors are continuously calculated and permanently stored if malfunctions of the following occur or if intake air leaks are present:
- Hot-wire mass air flow (MAF) sensor
- Injectors
- Purge control valve
- Diaphragm pressure regulator
- Purge valve

After eliminating the mentioned malfunctions or after trial installation of a LH-SFI control module from another vehicle, the LH-SFI control module's self-adaptation feature must be reset to its mean value. Programming and Relearning

The LH-SFI control module will also adapt itself during the course of vehicle operation.
