Code P2450 Acura Description
The PCM checks the purge flow conditions on both negative and boost pressure sides. If either side of the purge flow is detected as abnormal, it is determined that there is a clog or disconnection on the abnormal side of the purge line. If both sides of the purge flow are detected as abnormal, it is determined that the purge lines are abnormal, or the EVAP canister purge valve is stuck opened.
If non-return valve A is stuck opened, the boost pressure flows back to the fuel tank when the purge is controlled in a boost condition. At the time, the FTP sensor pulse waveform shows the opposite phase to the usual phase. The PCM detects a malfunction by calculating the phase time difference and stores a Diagnostic Trouble Code (DTC).
