Test Notes

Enter this pinpoint test only when directed here.

This pinpoint test is intended to diagnose the following:
- EVAP Canister Purge Solenoid
- Harness circuits: EVAP Canister Purge Solenoid and VPWR
- Powertrain Control Module

CAUTION: 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 Tester for OBD II (including the ultrasonic tester) is the only device to be used at this time for evaporative emission system leak detection.
