Monitor Description

The hybrid vehicle control ECU monitors the sensor voltage and uses this value to calculate the manifold absolute pressure. When the sensor output voltage deviates from the normal operating range, the hybrid vehicle control ECU interprets this as a malfunction in the manifold absolute pressure sensor and sets a DTC.

Example:

When the sensor output voltage remains less than 0.5 V, or more than 4.5 V for 0.5 seconds, the hybrid vehicle control ECU sets a DTC.

If the malfunction is not repaired successfully, a DTC is set 0.5 seconds after the engine is next started.
