PINPOINT TEST HX: Evaporative Emission (EVAP) System and Monitor: Introduction

WARNING: This page does not describe the selected car, but rather 31 other vehicles, including the 2011 Mercury Milan, 2011 Mercury Mariner, 2011 Mercury Grand Marquis, 2011 Lincoln Town Car, and 2011 Lincoln Navigator L. However, it is still accessible from the selected car via links, so may be relevant.

WARNING: CROWN VICTORIA POLICE INTERCEPTOR VEHICLES EQUIPPED WITH FIRE SUPPRESSION SYSTEM, REFER TO APPROPRIATE SERVICE INFORMATION 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.

Using a soap solution around the fuel filler cap or capless fuel tank filler pipe (if equipped) or using 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 Smoke Machine, Fuel Evaporative Emission System Tester 218-00001 or equivalent 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:

EVAP canister vent solenoid (9F945)
fuel filler cap (9030)
capless fuel tank filler pipe (9034)
fuel tank pressure (FTP) sensor (9C052)
EVAP canister purge (EVAPCP) valve (9C915)
EVAP system leaks using the Rotunda Smoke Machine, Fuel Evaporative Emission System Tester 218-00001
harness circuits: B+, CANV, EVAPCP, FTP, FTPREF, SIGRTN, VPWR and CASE GND
powertrain control module (PCM) (12A650)

For additional information on the EVAP system, refer to EVAPORATIVE EMISSION (EVAP) SYSTEMS .
