The fuel tank pressure (FTP) sensor output indicates about atmospheric pressure 0 kPa (0 in.Hg, 0 mmHg) When the FTP sensor indicates vacuum after starting the engine, there is the possibility of an FTP sensor However, if the fuel tank internal pressure is below the specified value (excessive vacuum is detected) when 1. If neither Temporary DTC (P1454 nor P2422) is stored, both DTCs are stored. 2. If both Temporary DTCs (P1454 and P2422) are stored and excessive vacuum is detected, both DTCs are stored. 3. If either Temporary DTC (P1454 or P2422) is stored and excessive vacuum is detected, the PCM stores the DTC of the Temporary DTC that was stored.
