Engine control in the 4.7-liter 4Runner
The engine control module uses sensor information to manage functions such as fuel delivery, ignition timing and emissions control. Its calibration helps determine how the V8 responds to driving conditions and, where applicable, coordinates engine operation with the automatic transmission.
The complete identifier 89663-35651 distinguishes this calibration from other Toyota files in the same part-number family. The catalog name does not establish a particular change made by this revision or identify a stock or modified variant. Exact vehicle compatibility requires confirmation against the control module and vehicle identification.
