STEP 6. Check connector C-60 at ECM <M/T> or connector 
C-54 at PCM <A/T> for damage.
Q: Is the connector in good condition?

YES : Repair harness wire between intake air temperature 

sensor connector B-14 and ECM connector C-60 
<M/T> or PCM connector C-54 <A/T> because of 
open circuit. Then go to Step 11.

NO :  Repair or replace it. Refer to GROUP 00E, Harness 

Connector Inspection 

P.00E-2

. Then go to Step 11.

STEP 8. Check the continuity at intake air temperature 
sensor harness side connector B-14.
(1) Disconnect the connector B-14 and measure at the harness 

side.

(2) Check for the continuity between terminal No. 5 and 

ground.

• Should be less than 2 ohms.

Q: Is the continuity normal?

YES : Replace the ECM or PCM. Then go to Step 11.
NO :  Go to Step 9.
