4-1. FUEL INJECTION SYSTEM

4-1-40

Is the voltage OK?

YES Go to step 2

• Loose or poor contacts on the ECU

coupler (terminal 42 or 27)

• Open or short circuit in the Y/R wire

or Gr/R wire

Step 1

(When sensor voltage is higher than specified)

1) Turn the ignition switch OFF.

2) Check the ECT sensor coupler for loose or

poor contacts.

If OK, then check the ECT sensor lead wire

continuity.

3) Remove the left side cover.

4) Disconnect the ECT sensor coupler.

5) Remove the ECU coupler.

6) Check the continuity between Y/R wire and

terminal 42.

7) Also, check the continuity between Gr/R wire

and terminal 27.

ECTS lead wire continuity: Continuity (sound)

Is the continuity OK?

YES Go to step 2

Y/R or Gr/R wire open

8) After repairing the trouble, clear the DTC

using Diagnosis tool.

Step 1

(When sensor voltage is lower than specified)

1) Turn the ignition switch OFF.

2) Check the ECT sensor coupler for loose or

poor contacts.

If OK, then check the ECT sensor lead wire

continuity.

3) Disconnect the ECT sensor coupler.

4) Check the continuity between Y/R wire and

ground.

5) If the sound is not heard from the tester, the

circuit condition is OK.

Tester knob indication: Continuity (sound)
