Monitor Description
WARNING: This page is about a different variant/trim than selected.
The ECM 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 ECM interprets this as a malfunction in the manifold absolute pressure sensor and stores 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 ECM stored a DTC.
