Engine control association
An engine control module uses sensor inputs to manage functions such as fuel injection, ignition timing and emissions control. These functions affect how the engine starts, runs and responds to the driver. The association with this particular calibration is tentative, and the identifier alone does not establish its exact vehicle application or the behavior changed by this revision.
The related catalog entry lists the same identifier, 89663-04341, without a vehicle name or variant label. It therefore does not identify a stock or modified version, a specific feature, or a compatible model.
