Pressure Sensor Switch Low

The code p0452 is set when the ecm reads a low voltage signal from the evap control system pressure sensor.

Pressure sensor switch low.

Start with locating the sensor as in some cars it can be an ac high pressure switch function and in some a low one. What does that mean. Circuit low input codes are often the result of low battery voltages that can have many possible causes bad connections across electrical connectors or previously repaired wiring as well as corrosion in electrical connectors.

This code uses two trip logic which means that the fault condition must be present during two successive cold starts and vehicle operation. Where is the a c low pressure sensor switch located and can it be replaced without opening the a c system. P1a pressure sensor pressure sensors switches view product. Are all these codes relate.

This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation. Whatever this sensor is you can locate it in the engine bay area. The evaporative control system pressure sensor low input code sets when the readings of the pressure sensor are below specification for ten seconds of vehicle operation after a cold start.
