O2 sensor LINCOLN MKZ 2017 Service Manual

Blocked Sensors If a message regarding a blocked sensor or
camera appears in the information display,
the radar signals or camera images are
obstructed. The radar sensor is located
behind a fascia cover near the driver side of
the lower grille. With an obstructed radar,
the Pre-Collision Assist system does not
function and cannot detect a vehicle ahead.
With the front camera obstructed, the
Pre-Collision Assist system does not respond
to pedestrians or stationary vehicles and the
system performance on moving vehicles
reduces. The following table lists possible
causes and actions for when this message
displays. Action
Cause
Clean the grille surface in front of the radar or remove the objectcausing the obstruction.
The surface of the radar in the grille is dirty or obstructed in some
way.
Wait a short time. It may take several minutes for the radar to detectthat there is no obstruction.
The surface of the radar in the grille is clean but the message remains
in the display.
The Pre-Collision Assist system is temporarily disabled. Pre-CollisionAssist should automatically reactivate a short time after the weather conditions improve.
Heavy rain, spray, snow, or fog is interfering with the radar signals.
The Pre-Collision Assist system is temporarily disabled. Pre-CollisionAssist should automatically reactivate a short time after the weather conditions improve.
Swirling water, or snow or ice on the surface of the road may interfere
with the radar signals.

Action
Cause
Contact an authorized dealer to have the radar checked for propercoverage and operation.
Radar is out of alignment due to a front end impact.
Clean the outside of the windshield in front of the camera.
The windshield in front of the camera is dirty or obstructed in some
way.
Wait a short time. It may take several minutes for the camera to detectthat there is no obstruction.
The windshield in front of the camera is clean but the message remains
in the display.
Note: Proper system operation requires a
clear view of the road by the camera. Have
any windshield damage in the area of the
camera's field of view repaired.
Note: If something hits the front end of your
vehicle or damage occurs, the radar sensing
zone may change. This could cause missed
or false vehicle detections. Contact an
authorized dealer to have the radar checked
for proper coverage and operation. Note:
If your vehicle detects excessive heat
at the camera or a potential misalignment
condition, a message may display in the
information display indicating temporary
sensor unavailability. This message
deactivates automatically when operational
conditions are corrected (for example, when
the ambient temperature around the sensor
decreases or the sensor automatically
recalibrates successfully). DRIVE CONTROL

Loss of air pressure may adversely affect tire
performance. For this reason:
Note:
Do not drive the vehicle above 50 mph
(80 km/h).
Note: Do not drive further than
120 mi
(200 km). Drive only to the closest authorized
Ford dealer or tire repair shop to have your
tire inspected.
• Drive carefully and avoid abrupt steering
maneuvers.
• Periodically monitor tire inflation pressure
in the affected tire; if the tire is losing
pressure, have the vehicle towed.
• Read the information in the Tips for Use
of the Kit section to make sure safe
operation of the kit and your vehicle.
Tips for Use of the Kit
To ensure safe operation of the kit:
• Read all instructions and cautions fully.
• Before operating the kit, make sure your
vehicle is safely off the road and away
from moving traffic. Turn on the hazard
lights. •
Always set the parking brake to ensure
the vehicle doesn't move unexpectedly.
• Do not remove any foreign objects, such
as nails or screws, from the tire.
• When using the kit, leave the engine
running (only if the vehicle is outdoors or
in a well-ventilated area) so the
compressor does not drain the vehicle's
battery.
• Do not allow the compressor to operate
continuously for more than 15 minutes.
This will help prevent the compressor
from overheating.
• Never leave the kit unattended during
operation.
• Sealant compound contains latex. Those
with latex sensitivities should use
appropriate precautions to avoid an
allergic reaction.
• Keep the kit away from children.
• Only use the kit when the ambient
temperature is between -22°F (-30°C) and
158°F (70°C)
. •
Only use the sealing compound before
the use-by date. The use-by date is on a
label on the sealant canister and can be
seen through the rectangular viewing
window on the bottom of the compressor.
Check the use-by date regularly and
replace the canister after four years of
non-use.
• Do not store the kit unsecured inside the
passenger compartment of the vehicle
as it may cause injury during a sudden
stop or crash. Always store the kit in its
original location.
• After sealant use, the tire pressure
monitoring system sensor and valve stem
on the wheel must be replaced by an
authorized Ford dealer.
• Operating the kit could cause an
electrical disturbance in radio, CD, and
DVD player operation. * When inflation only is required for
a tire or other objects, the selector
must be in the Air position.

WARNINGS
of loss of vehicle control, vehicle
rollover, personal injury and death.
Additionally the use of
non-recommended tires and wheels
could cause steering, suspension, axle,
transfer case or power transfer unit
failure. If you have questions regarding
tire replacement, contact your
authorized dealer as soon as possible. To reduce the risk of serious injury,
when mounting replacement tires
and wheels, you should not exceed the
maximum pressure indicated on the
sidewall of the tire to set the beads
without additional precautions listed
below. If the beads do not seat at the
maximum pressure indicated,
re-lubricate and try again.
When inflating the tire for mounting
pressures up to 20 psi (1.38 bar) greater
than the maximum pressure on the tire
sidewall, the following precautions must
be taken to protect the person mounting
the tire: WARNINGS
1. Make sure that you have the correct
tire and wheel size.
2. Lubricate the tire bead and wheel
bead seat area again.
3. Stand at a minimum of 12 ft (3.66 m)
away from the wheel and tire assembly.
4. Use both eye and ear protection.
For a mounting pressure more than
20 psi (1.38 bar)
greater than the
maximum pressure, a Ford dealer or
other tire service professional should do
the mounting.
Always inflate steel carcass tires with a
remote air fill with the person inflating
standing at a minimum of
12 ft (3.66 m)
away from the wheel and tire assembly. Important:
Remember to replace the
wheel valve stems when the road tires
are replaced on your vehicle It is recommended that the two front
tires or two rear tires generally be
replaced as a pair.
The tire pressure sensors mounted in
the wheels (originally installed on your
vehicle) are not designed to be used in
aftermarket wheels.
The use of wheels or tires not
recommended by Ford Motor Company
may affect the operation of your tire
pressure monitoring system.
If the tire pressure monitoring system
indicator is flashing, your system is
malfunctioning. Your replacement tire
might be incompatible with your tire
pressure monitoring system, or some
component of the system may be
damaged.

Note:
Each road tire is equipped with a tire
pressure sensor located inside the wheel
and tire assembly cavity. The pressure
sensor is attached to the valve stem. The
pressure sensor is covered by the tire and
is not visible unless the tire is removed. Take
care when changing the tire to avoid
damaging the sensor
You should always have your tires serviced
by an authorized dealer.
Check the tire pressure periodically (at least
monthly) using an accurate tire gauge. See
Inflating Your Tires in this chapter.
Understanding Your Tire Pressure
Monitoring System
The tire pressure monitoring system
measures pressure in your four road tires
and sends the tire pressure readings to your
vehicle. The low tire pressure warning light will turn
on if the tire pressure is significantly low.
Once the light is illuminated, your tires are
under-inflated and need to be inflated to the
manufacturer’
s recommended tire pressure.
Even if the light turns on and a short time
later turns off, your tire pressure still needs
to be checked. When Your Temporary Spare Tire is
Installed
When one of your road tires needs to be
replaced with the temporary spare, the
system will continue to identify an issue to
remind you that the damaged road wheel
and tire assembly needs to be repaired and
put back on your vehicle.
To restore the full function of the tire
pressure monitoring system, have the
damaged road wheel and tire assembly
repaired and remounted on your vehicle.
When You Believe Your System is Not
Operating Properly
The main function of the tire pressure
monitoring system is to warn you when your
tires need air. It can also warn you in the
event the system is no longer capable of
functioning as intended. See the following
chart for information concerning your tire
pressure monitoring system:
