EVAP System Pressure Sensor/Switch Low Input
Table of contents
P0452 SCION Possible Causes
- Faulty Evaporative Emission System (EVAP) Vapor Pressure Sensor
- Evaporative Emission System (EVAP) Vapor Pressure Sensor harness is open or shorted
- Evaporative Emission System (EVAP) Vapor pressure sensor circuit poor electrical connection
- EVAP system hose (pipe from air inlet port to canister pump module, canister filter, fuel tank vent hose)
- Faulty Engine Control Module (ECM)
How do I fix code P0452 SCION?
Check the “Possible Causes” listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins.
Cost of diagnosing the P0452 SCION code
The cost of diagnosing the P0452 SCION code is 1.0 hour of labor. The auto repair labor rates vary by location, your vehicle’s make and model, and even your engine type. Most auto repairs shops charge between $75 and $150 per hour.
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 SCION 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.
