Monitor Description
WARNING: This page is about a different variant/trim than selected.
- P0451: Pressure sensor noise
If the pressure sensor output fluctuates many times over 10 seconds, the ECM stops the EVAP system monitor, illuminates the MIL and sets DTC (2-trip detection logic).
- P0451: Pressure sensor stuck
If the pressure does not vary for 10 seconds, the ECM stops the EVAP system monitor, illuminates the MIL and sets DTC (2-trip detection logic).
- P0452: Pressure sensor low output
If the pressure sensor output is below 0.45 V, the ECM stops the EVAP system monitor, illuminates the MIL and sets DTC (1-trip detection logic). In this case, the pressure sensor or its circuit is open or shorted.
- P0453: Pressure sensor high output
If the pressure sensor output is 4.9 V or more, the ECM stops the EVAP system monitor, illuminates the MIL and sets DTC (1 -trip detection logic). In this case, the pressure sensor or its circuit is open or shorted.
