Circuit Description
WARNING: This page is about a different car, the 2003 Toyota RAV4, 2002 Toyota RAV4, 2002 Toyota Highlander, 2001 Toyota RAV4, and 2001 Toyota Highlander. However, it is still accessible from the selected car via links, so may be relevant.
Input turbine speed sensor detects rotation speed of input shaft. By comparing input turbine speed sensor signal and counter gear speed sensor signal, ECM detects shift timing of gears and controls engine torque and hydraulic pressure in response to various conditions to ensure smooth transaxle shifting. DTC will set if ECM detects vehicle speed of 20 MPH or more, transaxle in 2nd, 3rd or O/D gear, shift solenoids and PNP switch status normal, input shaft speed is 300 RPM or less, and output shaft speed is 1000 RPM or more. Possible causes are:
- Open or short in input turbine speed sensor circuit.
- Input turbine speed sensor malfunction.
- ECM malfunction.
