Code:
B143D 13
Definition:
EVAP Control System Incorrect Purge Flow (Includes Hybrid Models)
Description:
HYBRID MODELS CAUTION: Hybrid systems use very high-voltage battery systems.Before starting any service work involving the battery system,turn the ignition switch OFF and then remove the service plug from pocket in the trunk.After removing the service plug,wait 10 minutes before touching any of the high-voltage connectors and terminals.NOTE: If DTC P0441 is displayed with other DTC such as P2122, P2123 P2127, P2128, P2138, first perform trouble diagnosis for other DTC. Under normal conditions (non-closed throttle),sensor output voltage indicates if pressure drop and purge flow are adequate.If not,a malfunction is determined. EVAP control system does not operate properly -- EVAP control system has a leak between intake manifold and EVAP control system pressure sensor.
Cause:
 EVAP canister purge volume control solenoid valve stuck closed EVAP control system pressure sensor and the circuit Loose,disconnected or improper connection of rubber tube Blocked rubber tube Cracked EVAP canister EVAP canister purge volume control solenoid valve circuit Accelerator pedal position sensor Blocked purge port EVAP canister vent control valve Drain filter
Failure Type:
Circuit Open
This sub type is used for failures, where the control module determines an open circuit via lack of bias voltage, low current flow, no change in the state of an input in response to an output, etc.
