P0141/P0147/P0161/P0167 O2 Sensor Heater Circuit Malfunction

  • Make sure the iO2SS is properly powered. Measure the unit's power input (red wire) when the engine is on; you should measure >12V.
  • Ensure the iO2SS's signal outputs (green wires) are connected to the appropriate oxygen sensor signal wires leading to the PCM.
  • Verify all other wiring and check all solder joints or crimp connectors for loose connections, frayed wires, or corrosion.
  • Contact support@symtechlabs.com for further support.
