t EM: Emissions ComplianceE

da and some states or metropolitan areas in the United States require periodic Emission, or Inspection and Maintenance (I/M) Tests. All Fcts have been designed to pass these tests. If a Ford product fails an I/M Test, it is probable that 1) the engine or catalyst temperature was

and stabilized before the test, or 2) the vehicle had idled excessively before the test.If any emission components are replaced, perform the following before repeating the I/M Test procedure:1. Clear keep Alive Random Access Memory (RAM) - Refer to Powertrain Control Module (PCM) Reset. See: Reading and Clearing

Diagnostic Trouble Codes/Clearing Diagnostic Trouble Codes/With Scan Tool

2. To relearn some basic Adaptive Learning (trim) values, run engine at 2500 rpm for one minute and idle engine for two minutes.




Exhaust Gas Analysis Chart

ying an Excessive Grams Per Mile (GPM) Indication Using a Parts Per Million (PPM) Readingr the vehicle's gas reading(s) that is excessive, compare the actual GPM reading to the gas cutpoint level needed to pass testing. Determinech the actual GPM reading is over the cutpoint. This will give an indication of how much the PPM reading will have to be reduced (if theding is twice the cutpoint, the baseline reading will have to be cut in half or more). See following example.

mple:The actual HC produced by a vehicle was 1.6 GPM. The cutpoint for HC in this example is 0.8 GPM. The actual reading is twice the cuThe HC reading obtained for the same vehicle during the baseline drive averages 440 PPM. In order for this vehicle to pass the I/M test,

reading from the verification trip must be at least half of the baseline reading, or an average of 220 PPM or less.This method only gives a general idea of how much the PPM reading needs to be reduced in order for the vehicle to pass an I/M test thatcalculates GPM. This test is not exact. Experience will still have to be used to determine if the emission readings have been reduced enou

the vehicle to pass the I/M test.

Return fuel Systems return fuel to the fuel tank by means of a return line from the fuel rail.Mechanical return less fuel Systems do not return fuel to the fuel tank by means of a fuel return line. The fuel pressure regulator is mounthe Fuel Pump Module located in the fuel tank. Excess fuel is returned from this point.Electronic fuel systems do not return fuel to the fuel tank by means of a fuel return line. There is no fuel pressure regulator and pressure controlled by continuously varying the fuel pump speed through the Fuel Pump Driver Module (FPDM).

riptionr additional information on the Fuel Delivery System, refer to Description and Operation. See: Description and Operation

RNING: FUEL IN THE FUEL SYSTEM REMAINS UNDER HIGH PRESSURE EVEN WHEN THE ENGINE IS NOT RUNNINID INJURY OR FIRE, RELEASE THE FUEL PRESSURE FROM THE FUEL SYSTEM BEFORE DISCONNECTING ANY FU

E. TO RELEASE THE PRESSURE FROM THE SYSTEM PERFORM THE FOLLOWING:

CONNECT THE ROTUNDA FUEL PRESSURE GAUGE T8OL-9914-B OR EQUIVALENT AT THE SCHRADER VALVELOCATED ON THE FUEL RAIL. TESTING KIT VALVE MUST BE CLOSED.




GRADUALLY OPEN THE TESTING KIT VALVE TO RELIEVE FUEL PRESSURE IN THE VEHICLE FUEL SYSTEM AND DRAFUEL INTO A SUITABLE CONTAINER OR RETURN IT TO THE FUEL TANK.TO AVOID UNNECESSARY FUEL SPILLAGE AND FIRE HAZARD, ANYTIME FUEL LINES ARE DISCONNECTED, THE IGNSWITCH MUST BE IN THE OFF POSITION UNLESS FUEL PUMP OPERATION IS REQUIRED FOR TEST PURPOSES.

TION: Use care to prevent combustion from fuel spillage. No smoking, open flames or any kind of arcing.

E FUEL HANDLING PRACTICES

soline, Methanol and Methanol Blends

E

Report all fires to the appropriate authorities.Flames from methanol or methanol-gasoline blends can be invisible.

Know the locations of portable fire extinguishers, fire blankets, fire alarms and eye/wash shower facilities. Learn how to use themUse a B or AFFF (light water) type fire extinguisher to fight flammable liquid fires.

T AID

If swallowed:- If gasoline has been swallowed, do not induce vomiting. Seek medical attention immediately!

- If methanol or a methanol/gasoline blend has been swallowed, induce vomiting under the direction of a physician or Poison CCenter. Seek medical attention immediately!

When overcome by vapors, if safe, move victim to fresh air. If not breathing, give artificial respiration or CPR (Cardiopulmonar

Resuscitation) as appropriate. Seek medical attention immediately!If splashed in eyes, flush with large amounts of water for 15 minutes. Remove contact lenses, if worn. Seek medical attention.

If splashed on skin, remove contaminated clothing. Wash skin thoroughly with soap and water.

LTH

All fuels can be harmful or fatal if swallowed.

Be aware, if fuel is swallowed, onset of serious health effects can be delayed 12 to 24 hours.Fuels and products containing methanol (e.g. windshield washer fluid) can cause blindness if swallowed.

All fuel vapors can be harmful if inhaled.All fuels can be harmful if absorbed through the skin.

All fuels are irritating to the eyes and respiratory system.Some fuels made with gasoline contain benzene which is a cancer-causing agent.

DLING

Use flammable liquid handling precautions.Wear chemical goggles and nitrile gloves (additional protective clothing and equipment may be necessary in some instances).

Keep flammable liquids in approved, labeled, closed containers.Use in well-ventilated areas and control vapors. Be aware that vapors are not visible, are heavier than air, can travel along the flo

will settle in lower areas.When transferring flammable liquids, bond the receiving container to the source and ground the source to the earth.

Do not smoke or use heat/spark producing equipment near vapors.

Do not eat, smoke or drink where these products are handled, processed or stored.Never siphon by mouth.

Wash hands thoroughly after handling any fuel.

LS

Notify the proper authorities in the event of any spill you have not been trained to clean up.

Stop, contain, and clean up small spills with an absorbent material.

ia Fuel Shutoff (IFS) Switch - Reset Instructions

RNING: IF YOU SEE OR SMELL GASOLINE AT ANY TIME OTHER THAN DURING FUELING, DO NOT RESET THE INEL SHUTOFF (IFS) SWITCH.

Turn key off.Check for fuel leaks in the engine compartment.If no leak is present, reset the IFS switch by pushing the reset button on the top of the switch (refer to Owner Guide for switch location).

NOTE: In the closed position, the button can be depressed an additional 1.57 mm (1/16 inch) against a spring.

Turn key to on or start position for a few seconds, then off again.

Again, check for leaking fuel.

t QC: OBD II Monitor Testing Not Complete - DTC P1000E

ot necessary to clear DTC P1000 from the Powertrain Control Module (PCM) by driving the vehicle unless it is requested by the customepection/maintenance test.

m the customer of the need for additional driving when required to pass an inspection/maintenance test.

nostic Trouble Code (DTC) P1000 indicates that not all of the On Board Diagnostic II (OBD II) monitors have completed. In some statesmust be cleared to pass an inspection/maintenance test. The customer should be informed that the law specifies additional city and highwa

ng must be done to complete the check of the On Board Diagnostic system. This additional driving must occur before the vehicle is tested

ction/maintenance station. The amount of driving required varies with individual driving patterns. To complete this requirement in the shont of time refer to Drive Cycles. See: Monitors, Trips, Drive Cycles and Readiness Codes/Drive Cycles

nly way a DTC P1000 can be removed from memory is when all the OBD II monitors have successfully completed.

P1000 is set by the PCM with any of the following conditions:The vehicle is new from the factory and has not yet completed an OBD II Drive Cycle.The battery or PCM has been disconnected.

An OBD II monitor failure had occurred before completion of an OBD II Drive Cycle.The PCM DTCs have been cleared with a scan tool as part of a repair process.

P1000 cannot be cleared from the PCM when:The vehicle has a PTO and the circuit is shorted to VPWR or B+ or the PTO is on during testing.

chart is used to determine which test to run for the suspect circuit. Corresponding PIDs to each circuit are listed. Some circuits do not haveiated PID and will be measured with a digital multimeter. If the vehicle has a coil pack system with no start, perform the ignition test withbutorless ignition system tester. Do not use the DIST for coil on plug applications.
