The ECM calculates the air inlet duct internal pressure from the vacuum sensor assembly output voltage. If the vacuum sensor assembly output voltage is not within the normal range, there may be a malfunction in the vacuum sensor assembly or an open or short circuit. In this case, the ECM stores a DTC.
Example:
When the sensor output voltage is below 0.23 V for 3 seconds or more, the ECM stores a DTC.
