DTC P0442 Evaporative Emission (EVAP) System Small Leak Detected

Filed Under (Other Manuals) by admin on 17-01-2014

Download DTC P0442 Evaporative Emission (EVAP) System Small Leak Detected Refer to Engine Controls Routing Diagram, EVAP Control System Overview . System Description This DTC tests the evaporative emission (EVAP) system for a small leak. The control module monitors the fuel tank pressure (FTP) sensor signal to determine the vacuum decay rate. At an appropriate time, the control module turns the EVAP canister purge valve ON and the EVAP vent valve ON. This allows the engine to draw a vacuum on the EVAP system. At a calibrated time, or vacuum level, the control module turns the EVAP canister purge valve OFF, sealing the system, and monitors the FTP sensor input in order to determine the EVAP system vacuum decay. If the control module detects a leak larger than a calibrated amount, this DTC sets. The following table illustrates the relationship between the ON and OFF states, and the Open or Closed states of the EVAP canister purge and vent valves.… Read More
