EMISSION CONT ROL VISUAL INSPECT ION PROCEDURES
1983-93 GENERAL INFORMAT ION Em ission Control Visual Inspection Procedures
EMISSION CONTROL LABELS
This article is provided for general information only. Not all information applies to all makes and models. For more complete information, see
appropriate article(s) in the ENGINE PERFORMANCE Section.
The vehicle manufacturer's emission control label, also known as the underhood tune-up label or Vehicle's Underhood Emission Control
System (VECI) label, is located in the engine compartment. Information regarding year model of vehicle, engine size, number of cylinders,
emission equipment or type, engine tune-up specifications, whether vehicle was manufactured for sale in California or is a Federal vehicle,
vacuum hose routing schematic, etc., can be found on this label. See Fig. 1
.
In addition to the VECI label, some emission control inspection and maintenance programs may require an additional label to be affixed to the
vehicle in special circumstances. For example, in California, a Bureau Of Automotive Repair (BAR) engine label may be affixed to the left
door post. A BAR engine label is only used when the vehicle has an engine change, approved modification or is a Specially Constructed
(SPCN) or an acceptable Gray market vehicle. Check your state's emission control inspection and maintenance laws to determine if a simil ar
label is used.

FORD CALIBRATION LABELS
Ford Motor Co. uses an emission calibration label in addition to the emission control label. The emission calibration label is located on either
the engine valve cover, the driver-side door or the left door post pillar.
The calibration label identifies the engine year, calibration design and design revision level. These numbers are also used to identify service
parts and engine specifications that make up the emission system designed for the vehicle. See Fig. 2 , Fig. 3 , Fig. 5 and Fig. 6 .

carburetor. As the exhaust gas quickly warms the intake mixture, distribution is improved. This results in better cold engine driveability,
shorter choke periods and lower emissions.
Ensure EFE valve in exhaust manifold is not frozen or rusted in a fixed position. On vacuum-actuated EFE system, check EFE thermal vacuu
m
valve and check valve(s). Also check for proper vacuum hose routing. See Fig. 19
.

EMISSION MAINTENANCE REMINDER LIGHT (EMR)
If equipped, the EMR light (some models may use a reminder flag) reminds vehicle operator that an emission system maintenance is required.
This indicator is activated after a predetermined time/mileage.
When performing a smog check inspection, ensure EMR indicator is not activated. On models using an EMR light, light should glow when
ignition switch is turned to ON position and should turn off when engine is running.
If an EMR flag is present or an EMR light stays on with engine running, fail vehicle and service or replace applicable emission-related
components. To reset an EMR indicator, refer to appropriate MAINTENANCE REMINDER LIGHTS article in GENERAL INFORMATION.
MALFUNCTION INDICATOR LIGHT (MIL)
The Malfunction Indicator Light (MIL) is used to alert vehicle operator that the computerized engine control system has detected a
malfunction (when it stays on all the time with engine running). On some models, the MIL may also be used to display trouble codes.
As a bulb and system check, malfunction indicator light will glow when ignition switch is turned to ON position and engine is not running.
When engine is started, light should go out.

SERVICE & ADJUSTMENT SPECIFICATIONS
If you want a specification quickly, this is the place to look. Instead of hunting through a long article, we've separated out the important
specifications and arranged them into easy-to-use tables in a centralized location. You can find valuable information like spark plug wire
resistance, valve clearance, timing, firing orders, etc.
ADJUSTMENT
ON-VEHICLE ADJUSTMENTS
The ON-VEHICLE ADJUSTMENTS article contains the type of information that was previously thought of as TUNE-UP information.
Procedures for checking and adjusting valves, base ignition timing and idle speed are found in this section. Use this section in conjunction with
SERVICE & ADJUSTMENT SPECIFICATIONS for performing routine maintenance. Also, if you have a driveability problem, ensure all on-
vehicle adjustments are within specification before attempting further diagnosis.
THEORY & OPERATION
This article covers basic THEORY & OPERATION of engine performance-related systems and components. Before diagnosing vehicles or new
systems with which you are not completely familiar, read this article.
TESTING & DIAGNOSTICS
BASIC DIAGNOSTIC PROCEDURES/BASIC TESTING
The procedures listed in this article can help you avoid skipping a simple step early, like checking base timing, which could be costly in both
time and money later. This is also a potential starting point for diagnosis of a "no-start" condition. If all systems check out okay here, proceed
to SELF-DIAGNOSTICS/TESTS W/CODES or TROUBLE SHOOTING - NO CODES/TESTS W/O CODES article.
SELF-DIAGNOSTICS/TESTS W/CODES
Use this information to retrieve and interpret Diagnostic Trouble Codes (DTCs) accessed from the vehicle's self-diagnostic system. Once
information is retrieved, manufacturer diagnostic procedures are given to help pinpoint and repair computer system/component faults. Also
included are steps for clearing trouble codes once these faults are repaired. If there is a driveability symptom with no trouble codes set,
proceed to TROUBLE SHOOTING - NO CODES/TESTS W/O CODES article.
TROUBLE SHOOTING - NO CODES/TESTS W/O CODES
This is where to go when you have a problem that does not set a trouble code. It can help determine cause of problem using driveability
symptoms and intermittent testing procedures. Procedures in this information should lead you to a specific component or system test.
SYSTEM & COMPONENT TESTING
Here you will find various tests for engine performance systems and their components, such as air induction (turbochargers and superchargers),
fuel control, ignition control and emission systems.
PIN VOLTAGE CHARTS
These are supplied (when available from manufacturer) to quicken the diagnostic process. By checking pin voltages at the Powertrain Control
Module (PCM), you can determine if the PCM is receiving and/or transmitting proper voltage signals. Pin charts may also be referred to as PID
charts by some manufacturers.
SENSOR RANGE CHARTS
SENSOR OPERATING RANGE CHARTS
These are supplied (when available from manufacturer) to determine if a sensor is out of calibration. An out-of-calibration sensor may not set a
trouble code, but it may cause driveability problems.

50,000 m iles. Although som e m anufacturers do not recom m end replacem ent at a specified m ileage,
others require it at 60,000-100,000 m iles. A cam shaft drive belt failure m ay cause extensive dam age to
internal engine com ponents on m ost engines, although som e designs do not allow piston-to-valve
contact. T hese designs are often called "Free Wheeling". Many m anufacturers changed their
m aintenance and warranty schedules in the m id-1980's to reflect tim ing belt inspection and/or
replacem ent at 50,000-60,000 m iles. Most service interval schedules shown in this section reflect these
changes. Belts or com ponents should be inspected and replaced if any of the following conditions

Driven More Than 10 Miles Daily
No Operating Conditions From Severe Service Schedule
CAMSHAFT TIMING BELT
The condition of camshaft drive belts should always be checked on vehicles which have more than 50,000 miles. Although some
manufacturers do not recommend belt replacement at a specified mileage, others require it at 60,000-100,000 miles. A camshaft drive belt
failure may cause extensive damage to internal engine components on most engines, although some designs do not allow piston-to-va l ve
contact. These designs are often called "Free Wheeling".
Many manufacturers changed their maintenance and warranty schedules in the mid-1980's to reflect timing belt inspection and/or replacement
at 50,000-60,000 miles. Most service interval schedules in this manual reflect these changes.
Belts or components should be inspected and replaced if any of the following conditions exist:
Cracks Or Tears In Belt Surface
Missing, Damaged, Cracked Or Rounded Teeth
Oil Contamination
Damaged Or Faulty Tensioners
Incorrect Tension Adjustment
Replace camshaft timing belt every 60,000 miles.
