2000 FORD POSTAL EXPLORER check engine

WARNING LIGHTS AND CHIMES
Service engine soon
Your vehicle is equipped with a
computer that monitors the engine's
emission control system. This
system is commonly known as the
On Board Diagnostics System (OBD
II). The OBD II system protects the
environment by ensuring that your vehicle continues to meet
government emission standards. The OBD II system also assists the
service technician in properly servicing your vehicle.
TheService Engine Soonindicator light illuminates when the ignition is
first turned to the ON position to check the bulb. If it comes on after the
engine is started, one of the engine's emission control systems may be
malfunctioning. The light may illuminate without a driveability concern
being noted. The vehicle will usually be drivable and will not require
towing.
What you should do if the Service Engine Soon light illuminates
Light turns on solid:
This means that the OBD II system has detected a malfunction.
Temporary malfunctions may cause yourService Engine Soonlight to
illuminate. Examples are:
1. The vehicle has run out of fuel. (The engine may misfire or run
poorly.)
2. Poor fuel quality or water in the fuel.
3. The fuel cap may not have been properly installed and securely
tightened.

Engine coolant temperature gauge
Indicates the temperature of the
engine coolant. At normal operating
temperature, the needle remains
within the normal area (the area
between the ªHº and ªCº). If it
enters the red section, the engine is
overheating. Stop the vehicle as
soon as safely possible, switch off
the engine immediately and let the
engine cool. Refer toEngine coolantin theMaintenance and care
chapter.
Never remove the coolant reservoir cap while the engine is
running or hot.
This gauge indicates the temperature of the engine coolant, not the
coolant level. If the coolant is not at its proper level the gauge indication
will not be accurate. If the gauge enters the red section, the oil
pressure/engine coolant andCheck Engine/Service Engine Soon
indicators illuminate, refer toWhat you should know about fail-safe
coolingin theMaintenance and care chapter.

Battery voltage gauge
This shows the battery voltage when
the ignition is in the ON position. If
the pointer moves and stays outside
the normal operating range (as
indicated), have the vehicle's
electrical system checked as soon as
possible.
Engine oil pressure gauge
This shows the engine oil pressure
in the system. Sufficient pressure
exists as long as the needle remains
in the normal range (the area
between the ªLº and ªHº).
If the gauge indicates low pressure,
stop the vehicle as soon as safely
possible and switch off the engine
immediately. Check the oil level.
Add oil if needed (refer toEngine
oilin theMaintenance and care
chapter). If the oil level is correct, have your vehicle checked at your
dealership or by a qualified technician.

PREPARING TO START YOUR VEHICLE
Engine starting is controlled by the powertrain control system. This
system meets all Canadian Interference-Causing Equipment standard
requirements regulating the impulse electrical field strength of radio
noise.
When starting a fuel-injected engine, avoid pressing the accelerator
before or during starting. Only use the accelerator when you have
difficulty starting the engine. For more information on starting the
vehicle, refer toStarting the enginein this chapter.
Extended idling at high engine speeds can produce very high
temperatures in the engine and exhaust system, creating the risk
of fire or other damage.
Do not park, idle, or drive your vehicle in dry grass or other dry
ground cover. The emission system heats up the engine
compartment and exhaust system, which can start a fire.
Do not start your vehicle in a closed garage or in other enclosed
areas. Exhaust fumes can be toxic. Always open the garage door
before you start the engine. SeeGuarding against exhaust fumesin
this chapter for more instructions.
If you smell exhaust fumes inside your vehicle, have your dealer
inspect your vehicle immediately. Do not drive if you smell
exhaust fumes.
Important safety precautions
A computer system controls the engine's idle revolutions per minute
(RPM). When the engine starts, the idle RPM runs faster to warm the
engine. If the engine idle speed does not slow down automatically, have
the vehicle checked.
Before starting the vehicle:
1. Make sure all vehicle occupants have buckled their safety belts. For
more information on safety belts and their proper usage, refer to the
Seating and safety restraintschapter.
2. Make sure the vehicle accessories are off.

If you should unexpectedly have 85% alcohol in your fuel tank in
extremely cold temperatures with no way to use the engine block heater,
the engine may require extended crank times and several attempts to
start.
If the engine fails to start using the preceding instructions
1. Press the accelerator pedal 1/3 to 1/2 of the way to floor and hold.
2. Turn the key to START position.
3. When the engine starts, release the key, then release the accelerator
pedal gradually as the engine speeds up.
4. If the engine still fails to start, repeat steps one through three.
5. After the engine starts, hold your foot on the brake pedal, put the
gearshift lever in gear and release the parking brake. Slowly release the
brake pedal and drive away in a normal manner.
Guarding against exhaust fumes
Although odorless and colorless, carbon monoxide is present in exhaust
fumes. Take precautions to avoid its dangerous effects.
If you ever smell exhaust fumes of any kind inside your vehicle,
have your dealer inspect and fix your vehicle immediately. Do
not drive if you smell exhaust fumes. These fumes are harmful and
could kill you.
Have the exhaust and body ventilation systems checked whenever:
²the vehicle is raised for service.
²the sound of the exhaust system changes.
²the vehicle has been damaged in a collision.
WARNING:Engine exhaust, some of its constituents, and
certain vehicle components contain or emit chemicals known to
the State of California to cause cancer and birth defects or other
reproductive harm. In addition, certain fluids contained in vehicles and
certain products of component wear contain or emit chemicals known
to the State of California to cause cancer and birth defects or other
reproductive harm.

BRAKES
Your service brakes are self-adjusting. Refer to the scheduled
maintenance guide for scheduled maintenance.
Occasional brake noise is normal and often does not indicate a
performance concern with the vehicle's brake system. In normal
operation, automotive brake systems may emit occasional or intermittent
squeal or groan noises when the brakes are applied. Such noises are
usually heard during the first few brake applications in the morning;
however, they may be heard at any time while braking and can be
aggravated by environmental conditions such as cold, heat, moisture,
road dust, salt or mud. If a ªmetal-to-metal,º ªcontinuous grindingº or
ªcontinuous squealº sound is present while braking, the brake linings
may be worn-out and should be inspected by a qualified service
technician.
Four-wheel anti-lock brake system (ABS)
This vehicle is equipped with an anti-lock braking system (ABS). A noise
from the hydraulic pump motor and pulsation in the pedal may be
observed during ABS braking events. Pedal pulsation coupled with noise
while braking under panic conditions or on loose gravel, bumps, wet or
snowy roads is normal and indicates proper functioning of the vehicle's
anti-lock brake system. The ABS performs a self-check after you start
the engine and begin to drive away. A brief mechanical noise may be
heard during this test. This is normal. If a malfunction is found, the ABS
warning light will come on. If the vehicle has continuous vibration or
shudder in the steering wheel while braking, the vehicle should be
inspected by a qualified service technician.
The ABS operates by detecting the
onset of wheel lockup during brake
applications and compensates for
this tendency. The wheels are
prevented from locking even when
the brakes are firmly applied. The
accompanying illustration depicts
the advantage of an ABS equipped
vehicle (on bottom) to a non-ABS
equipped vehicle (on top) during hard braking with loss of front braking
traction.

RESETTING THE FUEL PUMP SHUT-OFF SWITCH
The fuel pump shut-off switch is a device intended to stop the electric
fuel pump when your vehicle has been involved in a substantial jolt.
After a collision, if the engine cranks but does not start, the fuel pump
shut-off switch may have been activated.
The fuel pump shut-off switch is located in the center of the dash on the
dash panel.
Use the following procedure to reset
the fuel pump shut-off switch.
1. Turn the ignition to the OFF
position.
2. Check the fuel system for leaks.
3. If no fuel leak is apparent, reset
the fuel pump shut-off switch by
pushing in on the reset button.
4. Turn the ignition to the ON
position. Pause for a few seconds and return the key to the OFF
position.
5. Make a further check for leaks in the fuel system.
FUSES AND RELAYS
Fuses
If electrical components in the
vehicle are not working, a fuse may
have blown. Blown fuses are
identified by a broken wire within
the fuse. Check the appropriate
fuses before replacing any electrical
components.
Always replace a fuse with one that has the specified amperage
rating. Using a fuse with a higher amperage rating can cause
severe wire damage and could start a fire.

Do not attempt to push start your vehicle. Automatic
transmissions do not have push-start capability.
Preparing your vehicle
When the battery is disconnected or a new battery is installed, the
transmission must relearn its adaptive strategy. As a result of this, the
transmission may shift firmly. This operation is considered normal and
will not effect function or durability of the transmission. Over time, the
adaptive learning process will fully update transmission operation to its
optimum shift feel.
1.Use only a 12±volt supply to start your vehicle.
2. Do not disconnect the battery of the disabled vehicle as this could
damage the vehicle's electrical system.
3. Park the booster vehicle close to the hood of the disabled vehicle
making sure the two vehiclesdo nottouch. Set the parking brake on
both vehicles and stay clear of the engine cooling fan and other moving
parts.
4. Check all battery terminals and remove any excessive corrosion before
you attach the battery cables. Ensure that vent caps are tight and level.
5. Turn the heater fan on in both vehicles to protect any electrical
surges. Turn all other accessories off.
Connecting the jumper cables
1. Connect the positive (+) booster cable to the positive (+) terminal of
the discharged battery.
Note:In the illustrations,lightning boltsare used to designate the
assisting (boosting) battery.
