Monitor Description
WARNING: This page is about a different variant/trim than selected.
The ECM monitors the manifold absolute pressure sensor voltage and uses this value to calculate the intake manifold pressure. When the manifold absolute pressure sensor output voltage deviates from the normal operating range, the ECM interprets this as a malfunction in the manifold absolute pressure sensor circuit, illuminates the MIL and stores a DTC.
Example:
If the manifold absolute pressure sensor output voltage is less than 0.5 V for 0.5 seconds or more, the ECM stores this DTC.
