P2406- 00
Evaporative Emission System Leak Detection Pump Sense Circuit High - No sub type information
Diagnostic monitoring tank leakage module circuit, short circuit to ground, short circuit to power, open circuit, high resistance
Blocked pipework Diagnostic monitoring tank leakage module failure
NOTE: Operational requirements needed to allow the monitor to be fully tested. Ensure that the vehicle has a fuel level between 15 and 85%, ambient temperature is between 32°F and 95°F, Ignition is on. Using the manufacturer approved diagnostic system carry out a "large leak test". Allow the diagnostic monitoring tank leakage test to complete, refer to diagnostic monitoring tank leakage test results
Refer to electrical circuit diagrams and check the diagnostic monitoring tank leakage module circuit for short circuit to ground, short circuit to power, open circuit, high resistance
Check for blocked pipework Check and install a new diagnostic monitoring tank leakage module as required
