STEP 15. Measure the resistance of the ground circuit at
crankshaft position sensor connector B-20.
(1) Disconnect connector B-20 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 resistance less than 2 ohms?

YES : Go to Step 21.
NO : Go to Step 16.

STEP 16. Measure the ground voltage at PCM connector
C-50 <2.4L Engine> or C-52 <3.0L Engine> by backprobing.
(1) Do not disconnect connector C-50 <2.4L Engine> or C-52

<3.0L Engine>.

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

(3) Measure the voltage between terminal 16 and ground by

backprobing.

• The voltage should measure 0.5 volt or less.

(4) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is the measured voltage 0.5 volt or less?

YES : Go to Step 17.
NO : Go to Step 19.

STEP 17. Check PCM connector C-50 <2.4L Engine> or
C-52 <3.0L Engine> for loose, corroded or damaged
terminals, or terminals pushed back in the connector.
Q: Are the connector and terminals in good condition?

YES : Go to Step 18.
NO : Repair or replace the damaged components. Refer to

STEP 18. Check the harness for open circuit or damage
between crankshaft position sensor connector B-20
terminal 1 and PCM connector C-50 <2.4L Engine> or C-52
<3.0L Engine> terminal 16.
Q: Is the harness wire in good condition?

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

STEP 19. Check PCM connector C-50 <2.4L Engine> or
C-52 <3.0L Engine> for loose, corroded or damaged
terminals, or terminals pushed back in the connector.
Q: Are the connector and terminals in good condition?

YES : Go to Step 20.
NO : Repair or replace the damaged components. Refer to
