Circuit Description: Notes

WARNING: This page is about a different car, the 2004 Toyota Corolla and 2003 Toyota Corolla. However, it is still accessible from the selected car via links, so may be relevant.

The vehicle speed sensor circuit is sent to cruise control ECU assy as a vehicle speed signal. For each rotation of the shaft, the vehicle speed sensor sends a signal through the combination meter assembly to the cruise control ECU assy (See the following chart). The cruise control ECU assy calculates the vehicle speed from this pulse frequency.
