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.
Check the resistance.

Description
Refer to dtc p0115 (see page es-105).
Monitor description
The resistance of the ect sensor varies in proportion to the actual ect. The
ect supplies a constant
voltage to the sensor and monitors the signal output voltage of the sensor. The
signal voltage output
varies acc ...
