1.Reset the ECM/PCM.
2.Start the engine.
Is DTC P0135 indicated?
YES - Go to 3.
NO - Intermittent failure, system is OK at this time. Check for poor connections or loose wires at the primary HO2S (Sensor 1) and at the ECM/PCM.n
3.Turn the ignition switch OFF.
4.Disconnect the primary HO2S (Sensor 1) 4P connector.
5.At the primary HO2S side, measure resistance between the primary HO2S (sensor 1) 4P connector terminals No. 3 and No. 4.

Is there about 6 W (at room temperature)?
YES - Go to 6.
NO - Replace the primary HO2S (Sensor 1).n
6.Check for continuity between body ground and the primary HO2S (Sensor 1) 4P connector terminals No. 3 and No. 4 individually.

Is there continuity?
YES - Replace the primary HO2S (Sensor 1).n
NO - Go to 7.
7.Turn the ignition switch ON (II).
8.Measure voltage between the primary HO2S (Sensor 1) 4P connector terminal No. 3 and No. 4.

Is there continuity?
YES - Repair short in the wire between the ECM/PCM (A1) and the primary HO2S (Sensor 1).n
NO - Substitute a known-good ECM/PCM and recheck. If symptom/indication goes away, replace the original ECM/PCM.n
13.Measure voltage between the primary HO2S (Sensor 1) 4P connector terminal No. 3 and body ground.

Is there battery voltage?
YES - Go to 14.
NO - Check the No. 16 (7.5A) fuse in the under-dash fuse/relay box. If the fuse is OK, repair open in the wire between the primary HO2S (Sensor 1) and No. 16 (7.5A) fuse.n
14.Turn the ignition switch OFF.
15.Disconnect the negative cable from the battery.
16.Reconnect the primary HO2S (Sensor 1) 4P connector.
17.Disconnect ECM/PCM connector A (31P).
18.Reconnect the negative cable to the battery.
19.Turn the ignition switch ON (II).
20.Measure voltage between ECM/PCM connector terminal A1 and A5.

Is there 0.1 V or less?
YES - Repair open in the wire between the ECM/PCM (A1) and the primary HO2S (Sensor 1).n
NO - Substitute a known-good ECM/PCM and recheck. If symptom/indication goes away, replace the original ECM/PCM.n
YES -
