Fuel Evaporative System Malfunction (P0453) Diagnosis and Solutions

Troubleshooting a KIA P0453 Code, "Evaporative Emission Control System Pressure Sensor High Input." P0453 code means that a reading from the engine's evaporative pressure sensor is higher than normal due to fuel tank vapor leaks into the system. P0453 DONGOBESH CENTRE · P0457 IGAWILO CENTRE · P0458 KASULU TEACHERS' COLLEGE CENTRE · P0461 JOHN PAUL II KAHAMA CENTRE · P0463 NGOREME CENTRE · P0464 ... Code P0453 is defined by SAE J2012 as "Evaporative Emission System Pressure Sensor/Switch High". So basically, the voltage on the Fuel Tank Pressure (FTP) ... I'm working on a 99 XJ8 4.0 V8. CEL keeps coming on and scans to a P0453 code. My research tells me its the fuel tank pressure sensor sending too high of a ... DTC P0453 is Fuel Tank Pressure Sensor (FTP) Circuit HIGH (means PCM computer detects voltage in this wire greater than 4.9 volts). Two possible ... The P0453 is a fairly straight forward code pointing to a problem with the EVAP system pressure sensor. This sensor is built into and part of the Pump Module. The PCM uses the Fuel Tank Pressure sensor voltage for EVAP system leak detection. This DTC sets when the Fuel Tank Pressure sensor signal goes above a ... P0453 Fault Code ... When this fault code is set the dashboard "Cruise", "seatbelt", and "check engine" lights are all lit or flashing. I've ... That fault code indicates there is an electrical circuit concern with the FTP sensor due to a failed sensor, wiring harness, or the PCM's signal ...
