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.
Reset the ECM/PCM.
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.
Disconnect the A/F Sensor 4P connector, and ECM/PCM connector C (31P).
Connect ECM/PCM connector terminals C14 and C15 to body ground with a jumper wire.
Check for continuity between A/F Sensor (Sensor 1) 4P connector terminal No.1, No.2, and body ground individuality. Is there continuity? YES - Replace the A/F Sensor (Sensor 1). NO - Repair open or short in the wire between the A/F Sensor (Sensor 1) and the ECM/PCM (C14 or C15).
