11. Check for continuity between PCM connector
terminal C1 (A8) and body ground.
Repair short in the wire between the PCM
(C1, A8 ) and the HO2S (primary or secondary )
(Sensor 1, Sensor 2 ).
Substitute a known-good PCM and recheck
(see page 11-5). If the symptom/indication goes
away, replace the original PCM.
12. Measure voltage between HO2S 4P connector
terminal No. 4 and body ground.
Go to step 13.
Repair open in the wire between the primary
HO2S (Sensor 1), secondary HO2S (Sensor 2) and
No. 6 ECU (PCM) CRUISE CONTROL (15A) fuse.
13. Turn the ignition switch OFF.
14. Reconnect the HO2S (primary or secondary )
(Sensor 1, Sensor 2 ) 4P connector.
15. Disconnect PCM connector C (31P) (PCM connector
A, 32P) .
16. Turn the ignition switch ON (II).
17. Measure voltage between PCM connector
terminals C1 (A8) and B2.
Substitute a known-good PCM and recheck
(see page 11-5). If the symptom/indication goes
away, replace the original PCM.
Repair open in the wire between the PCM
(C1, A8 ) and HO2S (primary or secondary )
(Sensor 1, Sensor 2 ).
