4. Measure resistance between terminals No. 3 and 4 at ECT sensor harness connector. Resistance should be 

infinite. If resistance is as specified, go to next step. If resistance is not as specified, repair circuits shorted 
to each other between ECT sensor and ECM. After repairs, erase DTC memory. See CLEARING 
DIAGNOSTIC TROUBLE CODES (FUNCTION 05) 
under SELF DIAGNOSTIC SYSTEM. Verify 
repair. Test is complete. Perform ECM relearn procedure. See TEST DRIVE RELEARN 
PROCEDURE 
.  

5. Measure resistance between ground and terminals No. 3 and 4 at ECT sensor harness connector. Both 

resistances should be infinite. If resistances are as specified, go to next step. If any resistance is not as 
specified, repair short to ground in wiring between ECT sensor and ECM. After repairs, erase DTC 
memory. See CLEARING DIAGNOSTIC TROUBLE CODES (FUNCTION 05) under SELF 
DIAGNOSTIC SYSTEM. Verify repair. Test is complete. Perform ECM relearn procedure. See TEST 
DRIVE RELEARN PROCEDURE 
.  

6. Measure resistance between positive battery terminal and terminals No. 3 and 4 at ECT sensor harness 

connector. Both resistances should be infinite.  

7. If resistances are as specified, replace ECM. After repairs, erase DTC memory. See CLEARING 

DIAGNOSTIC TROUBLE CODES (FUNCTION 05) under SELF DIAGNOSTIC SYSTEM. Verify 
repair. Test is complete. Perform ECM relearn procedure. See TEST DRIVE RELEARN 
PROCEDURE 
. If any resistance is not as specified, repair short to voltage in wiring between MAF 
sensor and ECM. After repairs, erase DTC memory. See CLEARING DIAGNOSTIC TROUBLE 
CODES (FUNCTION 05) 
under SELF DIAGNOSTIC SYSTEM. Verify repair. Test is complete. 
Perform ECM relearn procedure. See TEST DRIVE RELEARN PROCEDURE .
