The ECM monitors the sensor voltage and uses this value to calculate the IAT. When the sensor output voltage Example: If the sensor output voltage is more than 4.91 V for 0.5 seconds or more, the ECM determines that there is an If the malfunction is not repaired successfully, a DTC is set 0.5 seconds after the engine is next started.
