DTC
Description
Possible Cause
Action
P240C00 Evaporative emission
system leak detection
pump heater circuit high
Fuel tank leakage pump heater
control circuit: short circuit to
power
Fuel tank leakage monitoring pump
failure
Check the fuel tank leakage monitoring
pump and circuits. Refer to the electrical
guides. Install a new pump as necessary
P245000 Evaporative emission
control system switching
valve performance/stuck
open
Evaporative emission control
system switching valve (COV)
circuit: short circuit to ground
Evaporative emission control
system switching valve (COV)
circuit: open circuit
Evaporative emission control
system switching valve (COV)
circuit: short circuit to power
Evaporative emission control
system switching valve (COV) fault
Check the COV and circuits. Refer to the
electrical guides. Rectify as necessary.
Install a new COV as necessary (the COV
is integral with the fuel tank leakage
monitoring pump)

Pinpoint Tests
PINPOINT TEST A : EVAPORATIVE SYSTEM INCORRECT PURGE FLOW
TEST
CONDITIONS
DETAILS/RESULTS/ACTIONS
A1: CHECK FUEL FILLER CAP INSTALLATION AND CONDITION OF CANISTER, PIPES AND CONNECTORS
Make sure that the fuel filler cap is correctly installed and tightened.
Check the condition of the carbon canister.
Check the condition of all accessible pipes and connectors in the vapor line.
Are the canister and all pipes and connectors in good condition?
Yes
GO to A2
.
No
REPAIR as necessary. CLEAR the DTC, test the system for normal operation.
A2: CHECK THAT THE PURGE VALVE IS OPERATING
Disconnect the vapor pipe from the inlet port of the evaporative purge valve.
RUN the engine for 2 minutes, making sure that the engine reaches normal operating temperature.
Check that the evaporative purge valve is operating, by touch or by sound (using a stethoscope, it
will be possible to hear the valve operating).
Is the valve operating?
Yes
CHECK for related DTCs. Refer to the DTC Index above.
No
CHECK for purge valve related DTCs and refer to DTC Index.
