DIAGNOSTIC TROUBLE CODE PROCEDURES

23Ac-39

STEP 12. Measure the power supply voltage at crankshaft
position sensor connector B-36.
(1) Disconnect connector B-36 and measure at the harness

side.

(2) Turn the ignition switch to the "ON" position.

(3) Measure the voltage between terminal 3 and ground.

• The voltage should measure battery positive voltage.

(4) Turn the ignition switch to "LOCK" (OFF) position.
Q: Is the measured voltage battery positive voltage?

YES : Go to Step 15.
NO : Go to Step 13.

STEP 13. Check MFI relay connector B-22X for loose,
corroded or damaged terminals, or terminals pushed back
in the connector.
Q: Are the connectors and terminals in good condition?

YES : Go to Step 14.
NO : Repair or replace the damaged components. Refer to

STEP 14. Check the harness for open circuit or short
circuit to ground between MFI relay connector B-22X
terminal 1 and crankshaft position sensor connector B-36
terminal 3.
Q: Is the harness wire in good condition?

YES : Go to Step 4.
NO : Repair or replace the harness wire.

STEP 15. Measure the resistance of the ground circuit at
crankshaft position sensor connector B-36.
(1) Disconnect connector B-36 and measure at the harness

side.

(2) Measure the resistance between terminal 1 and ground.

• The resistance should measure less than 2 ohms.

Q: Is the measured resistance less than 2 ohms?

YES : Go to Step 18.
NO : Go to Step 16.
