Vehicle Speed Sensor
WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2002 Toyota RAV4, 2002 Toyota Highlander, 2002 Toyota Camry, 2002 Lexus RX 300, and 2001 Toyota RAV4. However, it is still accessible from the selected car via links, so may be relevant.
Vehicle speed signal is delivered to ABS ECU by ABS wheel speed sensors. ABS ECU converts signals into a 4-pulse signal and outputs signal to instrument cluster. Instrument cluster converts signal to a more precise waveform and outputs signal to ECM. Speed sensors are located at each wheel.
