So you have replaced the sensor.
DTC P1167: A/F SENSOR (SENSOR 1) HEATER SYSTEM MALFUNCTION
NOTE: If DTC P1162 is stored at the same time as DTC P1167, troubleshoot DTC P1162 first, then troubleshoot DTC P1167.
1. Reset the ECM/PCM
2. Start the engine. Wait for at least 80 seconds.
Is DTC P01167 indicated?
YES - Go to step 3.
NO - Intermittent failure, system is OK at this time. Check for poor connections or loose wires at C102 (located under the under-hood fuse/relay box), the A/F Sensor relay, the A/F Sensor (Sensor 1), and the ECM/PCM.
3. Disconnect the A/F Sensor 4P connector, and ECM/PCM connector C (31P).
4. Connect ECM/PCM connector terminals C14 and C15 to body ground with a jumper wire.
5. Check for continuity between A/F Sensor (Sensor 1) 4P connector terminal No. 1, No. 2, and body ground individually.
Is there continuity?
YES - Replace the A/F Sensor (Sensor 1) (see Primary HO2S & A/F Sensor Replacement ).
NO - Repair open or short in the wire between the A/F Sensor (Sensor 1) and the ECM/PCM (C14 or C15).
