P0452 - Evaporative Emission Control System Pressure Sensor Low Input

Possible causes
- Faulty Evaporative Emission System (EVAP) Pressure sensor
- Evaporative Emission System (EVAP) Pressure sensor harness is open or shorted
- Evaporative Emission System (EVAP) Pressure sensor circuit poor electrical connection
What does this mean? What does this mean?
When is the code detected?
An excessively low voltage from the sensor is sent to Engine Control Module (ECM).
Possible symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
P0452 Description

The Evaporative Emission System (EVAP) control system pressure sensor detects pressure in the purge line. The sensor output voltage to the Engine Control Module (ECM) increases as pressure increases. The EVAP control system pressure sensor is not used to control the engine system. It is used only for on board diagnosis.
