  • Ensure the oxygen sensor’s heater circuit element is within the OEM’s specifications.
  • If using the heater circuit simulator included with the iO2SS, ensure it is connected to the correct wires.
  • Inspect the wiring harness for open circuits.
  • Ensure the oxygen sensor heater circuit’s fuse isn’t blown.
  • If this problem persists, your car may require a lower resistance heater circuit simulator. In this case, contact support@symtechlabs.com for further support.
