      My 2006 Accord I4 4dr sedan SE gave me the following codes this morning:
      P0139 – Secondary Heated Oxygen Sensor (Secondary HO2S) Slow Response
      P0113 – Intake Air Temperature (IAT) Sensor Circuit High Voltage
      P0102 – Mass Airflow (MAF) Sensor Circuit Low Voltage

      – My Accord is a Canadian version.
      – This morning the outside temperature was -11°C when the check engine light came on.

      Which sensor should I check first?
      You help will be appreciated.

        Sounds like a voltage problem. Did it start OK? Is it showing 14V at the battery when running?

          I can still start my Accord. I got 14.4V at the battery terminal after my Accord was running.

          I took out the MAF sensor and used CRC MAF sensor cleaner to clean it.
          Clear the code. Now, I need to go out for a test drive to determine whether the check engine light comes back again of not.
