Enter this Pinpoint Test only when directed here.
The use of a soap solution, such as SNOOP, around the fuel filler cap or the use of the hydrocarbon emission analyzer to determine an evaporative emission system leak is not recommended. The mandatory Rotunda Evaporative Emission System Leak Tester for OBD II (including the ultra-sonic tester) is the only device to be used at this time for evaporative emission system leak detection.
This Pinpoint Test is intended to diagnose the following:
Canister Vent (CV) solenoid
Fuel filler cap
Fuel Tank Pressure (FTP) sensor
In-line Fuel Tank Pressure (FTP) sensor
EVAP canister purge valve
Harness circuits: CV, FLI, FTP, EVAP Canister Purge Valve, SIG RTN, Vehicle Power (VPWR), Reference Voltage (VREF) and Power Ground (PWR GND)
Powertrain Control Module (PCM)
Evaporative Emission (EVAP) Monitor System
