Tests HX: Evaporative Emission (EVAP) Monitor and System
NOTE
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)
