Ect sensor inspection

Refer to “dtc “c15” (p0115-h/l): ect sensor circuit malfunction” in section 1a .

Inspect the ect sensor in the following procedures:

1. 1
   remove the ect sensor. Refer to “ect sensor removal and installation” .
2. 2
   Connect the ect sensor (1) to the circuit tester and place it in the oil (2) contained in a pan, which is placed on a stove.
3. 3
   Heat the oil to raise its temperature slowly and read the column thermometer (3) and ohmmeter.

   If the ect sensor ohmic value does not change in the proportion indicated, replace it with a new one.

• take special care when handling the ect sensor. It may cause damage if it gets an excessive sharp impact.
• Do not contact the ect sensor and column thermometer with a pan.

Special tool (a): 09900–25008 (multi circuit
tester set)

4. Install the ect sensor. Refer to “ect sensor removal and installation” .
