Toyota RAV4 Service Manual: Intermediate shaft speed sensor "A"

Toyota RAV4. Intermediate shaft speed sensor "a"


Description

This sensor detects the rotation speed of the counter gear. By comparing the counter gear speed signal (nc) with the direct clutch speed sensor signal (nt), the ecm detects the shift timing of the gears and approximately controls the engine torque and hydraulic pressure according to various conditions. Thus smooth gear shifting is performed.

Toyota RAV4. Intermediate shaft speed sensor "a"


Monitor description

The nc terminal of the ecm detects revolution signals from speed sensor nc (counter gear rpm). The ecm calculates gear shifts by comparing speed sensor nt with speed sensor nc.

While the vehicle is operating in the 2nd, 3rd or o/d gear position with the shift lever on d, if the counter gear revolution is less than 300 rpm*1 and the output shaft revolution is more than 1,000 rpm*2, the ecm detects the trouble, illuminates the mil and stores the dtc.

*1: Pulse is not output or is irregularly output.

*2: The vehicle speed is 50 km/h (31 mph) or more.

Inspection procedure

Hint:

Using the intelligent tester's data list allows switch, sensor, actuator and other item values to be read without removing any parts. Reading the data list early in troubleshooting is one way to save time.

Notice:

In the table below, the values listed under "normal condition" are reference values. Do not depend solely on these reference values when deciding whether a part is faulty or not.

  1. Warm up the engine.
  2. Turn the ignition switch off.
  3. Connect the intelligent tester to the can vim. Then connect the can vim to the dlc3.
  4. Turn the ignition switch on and turn the tester on.
  5. Enter the following menus: diagnosis / enhanced obd ii / data list.
  6. Follow the instructions on the tester and read the data list.
