(2) Check for the continuity between terminal No. 2 and

ground.

• Should be less than 2 ohms.

Q: Is the continuity normal?

YES : Go to Step 3.
NO : Repair harness wire between knock sensor connector

B-35 (terminal No. 2) and ground because of open
circuit or harness damage. Then go to Step 6.

STEP 3. Check connector C-62 at ECM <M/T> or connector
C-59 at PCM <A/T> for damage.
Q: Is the connector in good condition?

YES : Go to Step 4.
NO : Repair or replace it. Refer to GROUP 00E, Harness

Connector Inspection

P.00E-2

. Then go to Step 6.

STEP 4. Check for open circuit and short circuit to ground
and harness damage between knock sensor connector
B-35 (terminal No. 1) and ECM connector C-62 (terminal
No. 91) <M/T> or PCM connector C-59 (terminal No. 90)
<A/T>.
Q: Is the harness wire in good condition?

YES : Go to Step 5.
NO : Repair it. Then go to Step 6.
