INTRODUCTION

Note. References to Econoline include Cutaway and RV Cutaway. References to F250-550 Super Duty Pickup include Cab & Chassis.

Note. Testing individual components does not isolate shorted or open circuits. Perform all voltage tests with a Digital Volt-Ohmmeter (DVOM) with a minimum 10-megohm input impedance, unless stated otherwise in test procedure. Use ohmmeter to isolate shorted or open wiring harness. For identification of circuits and terminals referenced in test procedures, see WIRING DIAGRAMS article.

Before testing separate components or systems, perform appropriate procedures in BASIC DIAGNOSTIC PROCEDURES - CARS or BASIC DIAGNOSTIC PROCEDURES - TRUCKS - EXCEPT DIESEL article. Computer-controlled and monitored components should set a Diagnostic Trouble Code (DTC) if they malfunction. Check for Key On Engine Off (KOEO), Key On Engine Running (KOER) and/or Continuous Memory DTCs prior to testing individual components. Perform QUICK TEST procedures in SELF-DIAGNOSTICS - EEC-V - GASOLINE & NGV article. In many cases a circuit that is open, or shorted to ground or power can be at fault. Component replacement is only suggested after testing and passing circuits and control devices. A component test may direct you to a system test in SELF-DIAGNOSTICS - EEC-V - GASOLINE & NGV article to help avoid replacement of a good component. If the component can be tested properly on its own, it will be included here.

Removal & Installation

On models with console, open storage bin and press clips to remove storage bin. Press and hold lock clip and slide console up to remove. On all models, remove instrument panel cover under steering column. Disconnect 4 engine cover latches and remove engine cover. To install, reverse removal procedure.

CATALYTIC CONVERTER

Note. If vehicle fails emissions test or catalytic converter efficiency is in question, perform EMISSIONS COMPLIANCE procedures. See EMISSIONS COMPLIANCE .

EMISSIONS COMPLIANCE

Canada and some states or metropolitan areas in the United States require periodic emission, or Inspection/Maintenance (I/M) tests. All Ford products have been designed to pass these tests. If a Ford vehicle fails an I/M test, ensure correct model, year, test weight (less than vehicle's GVW) and correct calibration (California or Federal) are on the test report.

Identify which gas readings are high or low and identify in which mode the gas(es) failed. If all gases were high at the beginning of the test then decreased, the engine or catalytic converter temperature may not have been at operating temperature and stabilized prior to the test, or the vehicle had idled for an excessive period of time prior to the test. Perform DIAGNOSTIC ROUTINES after analyzing I/M test report.

If any emission component is changed, Keep-Alive Memory (KAM) should be cleared and basic adaptive strategy should be relearned before repeating state emission test procedure. To clear KAM and perform basic adaptive strategy, perform KEEP ALIVE RANDOM ACCESS MEMORY RESET PROCEDURE under CLEARING CODES under SELF-DIAGNOSTIC SYSTEM in SELF-DIAGNOSTICS - EEC-V - GASOLINE & NGV article.

Diagnostic Routines

1. 1) Analyze Vehicle Inspection/Maintenance (I/M) Test Report Ensure vehicle Inspection/Maintenance (I/M) test report has been analyzed. Check for data entry errors, correct model, year, vehicle test weight and correct calibration (California or Federal). Identify which gas readings are HIGH and which were LOW. If report includes a drive trace, identify during which mode the gas(es) failed. When report has been analyzed completely, go to next step.
2. 2) Vehicle Failed EVAP Compliance If vehicle failed an EVAP Emissions System Leak Test or a Purge Flow Test only, go to step 35) . If vehicle failed EVAP, Purge Flow and gas tests, go to next step.
3. 3) Baseline Vehicle Using an exhaust gas analyzer, baseline vehicle. If vehicle must be driven to achieve baseline, ensure baseline drive cycle is able to be repeated to verify the repairs. During baseline, check for any related symptoms that may be present (driveability, A/T shifting or exhaust smoke). When vehicle has been baselined, go to next step.
4. 4) Check For Other Symptoms Check for driveability concerns (including idle and A/T shifting concerns, exhaust smoke and for cooling system concerns (engine unable to reach normal operating temperature). If other symptoms are present, perform «QUICK TEST»(/ford/explorer-sport-trac/i-2000-2005/remont/testing-diagnostics/#engine-controls-self-diagnostics-eec-v-gasoline-ngv) in SELF-DIAGNOSTICS - EEC-V - GASOLINE & NGV article.

If resistance is not 48-65 ohms, replace CV solenoid and repeat QUICK TEST in SELF-DIAGNOSTICS - EEC-V - GASOLINE & NGV article. If resistance is 48-65 ohms, solenoid is okay. If fault is still present, perform TEST HX: EVAPORATIVE EMISSION MONITOR & SYSTEM under SYSTEM TESTS in SELF-DIAGNOSTICS - EEC-V - GASOLINE & NGV article.

EVAP Canister (All Models)

There are no moving parts in canister. Check for loose, missing, cracked or broken connections and parts. Repair or replace canister as necessary. There should be no liquid in canister.

Note. EVAP canister purge valve resistance reading must be taken with engine cooled down.

Turn ignition switch to OFF position. Disconnect EVAP canister purge valve. Using a DVOM, measure resistance between EVAP canister purge valve terminals. If resistance is not 30-38 ohms, replace EVAP canister purge valve. Perform EVAPORATIVE EMISSIONS SYSTEM LEAK TEST under EVAPORATIVE EMISSION SYSTEM TESTS to verify repair. If resistance is 30-38 ohms, EVAP canister purge valve is okay.

For additional Electric Exhaust Gas Recirculation (EEGR) system testing and specifications, see TEST KD: ELECTRIC EXHAUST GAS RECIRCULATION under SYSTEM TESTS in SELF-DIAGNOSTICS - EEC-V - GASOLINE & NGV article.

Exhaust Gas Recirculation

1. Ensure all vacuum hoses are correctly routed and securely attached. Replace any crimped or broken hoses. Ensure there is less than one in. Hg vacuum to EGR valve at idle with engine at normal operating temperature. Install tachometer. Disconnect Idle Air Control (IAC) wiring harness connector. Remove and plug vacuum hose at EGR valve. Place transmission in Neutral.
2. Start and operate engine at idle. Note idle speed. Using a hand-held vacuum pump, slowly apply 5-10 in. Hg vacuum to EGR valve. When vacuum is fully applied, engine should do one or more of the following: Engine should stall. Idle speed should drop more than 100 RPM. Idle speed should return to normal when vacuum is released.
3. Service or replace EGR valve if engine does not stall or idle speed does not respond as specified. Reconnect IAC harness connector. Unplug and reconnect vacuum hose at EGR valve. For additional EGR system testing and specifications, go to «TEST HE: EGR SYSTEM»(/ford/explorer-sport-trac/i-2000-2005/remont/testing-diagnostics/#engine-controls-self-diagnostics-eec-v-gasoline-ngv) under SYSTEM TESTS in SELF-DIAGNOSTICS - EEC-V - GASOLINE & NGV article.

POSITIVE CRANKCASE VENTILATION

Note. Use this test to diagnose Positive Crankcase Ventilation (PCV) valve and related vacuum hoses only.

1. 1) Stuck PCV Valve Check Ensure PCV valve maintenance schedule has been followed. Ensure proper PCV valve is installed. Remove PCV valve. Shake valve and listen for rattle. If PCV valve rattles when shaken, install PCV valve and go to next step. Replace PCV valve if it does not rattle when shaken. Verify repair.
2. 2) PCV System Check Start engine and warm to normal operating temperature. Disconnect fresh air hose from remote air cleaner or outlet tube connecting MAF sensor to throttle body. Place a stiff piece of paper over end of hose. If vacuum from hose does not hold paper in place for one minute, go to next step. If vacuum from hose holds paper in place for one minute, PCV system is okay. Return to «SYMPTOM DIAGNOSIS»(/ford/explorer-sport-trac/i-2000-2005/remont/testing-diagnostics/#engine-controls-trouble-shooting-no-codes-eec-v-gasoline-ngv__symptom-diagnosis) under SYMPTOMS in TROUBLE SHOOTING - NO CODES - EEC-V - GASOLINE & NGV article to complete testing.
3. 3) Evaporative Emission System Check Disconnect evaporative emission hose from PCV system and plug connector. Again, place a stiff piece of paper over end of hose. If vacuum from hose does not hold paper in place for one minute, isolate vacuum leak or restriction in PCV system and repair as necessary. If vacuum from hose holds paper in place for one minute, PCV system is working properly at this time. Go to «EVAPORATIVE EMISSION SYSTEM TESTS»(/ford/explorer-sport-trac/i-2000-2005/remont/testing-diagnostics/#engine-controls-system-component-tests-eec-v-gasoline__evaporative-emission-system-tests) to diagnose EVAP system vacuum leak.
