DTC P0452 EVAP Control System Pressure Sensor: Wiring Diagram
WARNING: This page is about a different car, the 2010 Infiniti M45. However, it is still accessible from the selected car via links, so may be relevant.
Specification data are reference values and are measured between each terminal and ground.
CAUTION:
Never use ECM ground terminals when measuring input/output voltage. Doing so may result in damage to the ECM's transistor. Use a ground other than ECM terminals, such as the ground.
