Tests HX: Evaporative Emission (EVAP) System and Monitor

PINPOINT TEST HX: EVAPORATIVE EMISSION (EVAP) MONITOR AND SYSTEM

WARNING: Crown Victoria Police Interceptor vehicles equipped with fire suppression system, refer to Section 419-03 for Important Safety Warnings. Failure to follow these instructions may result in personal injury.

WARNING: Before repairing or installing a new component in the fuel system, reduce the possibility of injury or fire by following the warning, caution, and handling directions in pinpoint test HC. Failure to follow these instructions may result in personal injury

Note: Use this pinpoint test only when directed here.

The use of a soap solution 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 On Board Diagnostic (OBD) (including the ultrasonic tester) and the Rotunda Vacutec 522 Leak Detector Smoke Machine are the only devices to be used at this time for evaporative emission system leak detection.

When using the Rotunda Smoke Machine Fuel Evaporative Emission System Tester 218-00001 or equivalent the fuel level in the fuel tank must be less than 85% full

This pinpoint test is intended to diagnose the following:

^ canister vent (CV) solenoid (9F945)
^ fuel filler cap (9030)
^ fuel tank pressure (FTP) sensor (9C052)
^ EVAP canister purge (EVAPCP) valve (9C915). Also known as the vapor management valve (VMV).
^ EVAP system leaks using the Rotunda Vacutec Leak Detector Smoke Machine.
^ harness circuits: B+ CV EVAPCP FCIL FLI FTP SIGRTN VPWR VREF and CASE GND
^ powertrain control module ( PCM) (12A650)
