DTC P24D6: General Description
The powertrain control module (PCM) monitors the leak check pressure sensor output voltage. The leak check pressure sensor output voltage rises as the fuel tank pressure increases. Conversely, the leak check pressure sensor output voltage drops as the fuel tank pressure decreases. Rapid changes in the leak check pressure sensor output voltage due to electrical noise or an intermittent open during the EVAP leak detection may cause incorrect leak detection, so abnormal output is monitored. If the leak detection pressure sensor output voltage change occurs for specified ratio within a set time, the PCM detects a malfunction and stores a DTC.
