Toyota RAV4 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.
Disconnect connectors a and c, and measure
the resi ...
Check and replace ecu
Notice:
The connector should not be disconnected from
the ecu. Perform the inspection from the
backside of the connector on the wire harness
side.

Transmission fluid temperature sensor "A" circuit
Description
The automatic transmission fluid (atf) temperature sensor converts the atf
temperature into a
resistance value which is input into the ecm.
The ecm applies a voltage to the temperature sensor through ecm terminal tho1.
The sensor resistance changes with the atf temperature. ...
