DTC P0452: - Evaporative Emission System Pressure Sensor/Switch Low
DTC P0452: - EVAPORATIVE EMISSION SYSTEM PRESSURE SENSOR/SWITCH LOW
| Description: | The powertrain control module (PCM) monitors the evaporative emission (EVAP) control system fuel tank pressure (FTP) sensor input signal to the PCM. The test fails when the signal average drops below a minimum allowable calibrated parameter. | ||
| Possible Causes: |
|
||
| Diagnostic Aids: | An FTP voltage parameter identification (PID) reading less than 0.22 volt with the ignition on, engine off or ignition on, engine running, indicates a concern is present. | ||
| Application | Key On Engine Off | Key On Engine Running | Continuous Memory |
