Monitor Description
WARNING: This page is about a different car, the 2020 Toyota RAV4 and 2019 Toyota RAV4. However, it is still accessible from the selected car via links, so may be relevant.
The ECM monitors the pressure inside the intake manifold while opening and closing the EGR valve during fuel cut operation. If there is no change in the manifold absolute pressure sensor value, the ECM interprets this as a malfunction of the EGR valve assembly, illuminates the MIL and stores this DTC.
