Toyota RAV4 (XA40) 2013-2018 Service Manual: Check for short circuit
- If the wire harness is ground shorted (fig. 5), Locate the section by conducting a resistance check with the body ground (below).
- Check the resistance with the body ground.
- Disconnect connectors a and c, and measure the resistance
Standard resistance (fig. 6)
Hint:
Measure the resistance while lightly shaking the wire harness vertically and horizontally.
If the results match the examples above, a short circuit exists between terminal 1 of connector a and terminal 1 of connector c.
- Disconnect connector b and measure the resistance.
Standard resistance (fig. 7)
If the results match the examples
above, a short
circuit exists between terminal 1 of connector b2
and terminal 1 of connector c.
If the results match the examples above, a short circuit exists between terminal 1 of connector b2 and terminal 1 of connector c.
Check for open circuit
For an open circuit in the wire harness in fig. 1,
Check the resistance or voltage, as described below.

Throttle actuator control system
Description
The throttle actuator is operated by the ecm, and opens and closes the
throttle valve using gears. The
opening angle of the throttle valve is detected by the throttle position (tp)
sensor, which is mounted on
the throttle body. The tp sensor provides feedback to the ecm in ord ...
