2014 FIAT 500 sensor

The TPMS consists of the following components:
•Receiver module
• Four Tire Pressure Monitoring Sensors
• Various Tire Pressure Monitoring System messages,
which display in the Electronic Vehicle Information
Center (EVIC)
• Tire Pressure Monitoring Telltale Light
Tire Pressure Monitoring Low Pressure Warnings
The “Tire Pressure Monitoring Telltale Light” will
illuminate in the instrument cluster and a chime will
sound when tire pressure is low in one or more of the
four active road tires. In addition, the Electronic
Vehicle Information Center (EVIC) will display a
graphic showing the pressure values of each tire with
the low tire pressure tire highlighted in a different
color.
Should this occur, you should stop as soon as possible
and inflate the tires with low pressure to the vehicle’s
recommended cold placard pressure value. Once the
system receives the updated tire pressures, the system
will automatically update and the “Tire Pressure Moni-
toring Telltale Light” will turn off. The vehicle may need

to be driven for up to 20 minutes above 15 mph
(24 km/h) in order for the TPMS to receive this informa-
tion.
TPMS Warning
When a system fault is detected, the “Tire Pressure
Monitoring Telltale Light” will flash on and off for 75
seconds and then remain on solid. The system fault will
sound a chime and also display a “Service Tire Pressure
Monitoring System” message in the EVIC for approxi-
mately 5 seconds and then display dashes (--) in place of
the pressure value to indicate which sensor is not being
received.If the ignition switch is cycled, this sequence will repeat,
providing the system fault still exists. If the system fault
no longer exists, the “Tire Pressure Monitoring Telltale
Light” will no longer flash, and the “Service Tire Pressure
Monitoring System” message will no longer display, and
a pressure value will display in place of the dashes.
Service TPM System Message
290 STARTING AND OPERATING

A system fault can occur due to any of the following:
1. Signal interference due to electronic devices or drivingnext to facilities emitting the same radio frequencies as
the TPM sensors.
2. Installing aftermarket window tinting that contains materials that may block radio wave signals.
3. Accumulation of snow or ice around the wheels or wheel housings.
4. Using tire chains on the vehicle.
5. Using wheels/tires not equipped with TPM sensors.
The EVIC will also display a Service Tire Pressure
Monitoring System message for a minimum of five
seconds when a system fault related to an incorrect
sensor location fault is detected. In this case, the Service
Tire Pressure Monitoring System message is then fol-
lowed with a graphic display with pressure values still shown. This indicates that the pressure values are still
being received from the TPM sensors but they may not be
located in the correct vehicle position. The system still
needs to be serviced as long as the
Service Tire Pressure
Monitoring System message is displayed.
NOTE:
• The TPMS will not monitor the pressure in a replace-
ment tire installed without a tire pressure sensor.
• If you install a replacement tire in place of a road tire
that has a pressure below the low-pressure warning
limit, upon the next ignition switch cycle, the “Tire
Pressure Monitoring Telltale Light” will remain on and
a chime will sound. In addition, the graphic in the
EVIC will still display a pressure value highlighted in
a different color.
• After driving the vehicle for up to 20 minutes above
15 mph (24 km/h), the “Tire Pressure Monitoring

Telltale Light” will flash on and off for 75 seconds and
then remain on solid. In addition, the EVIC will
display a “Service TPM System” message and then
display dashes (- -) in place of the pressure value.
• For each subsequent ignition switch cycle, a chime will
sound, the “Tire Pressure Monitoring Telltale Light”
will flash on and off for 75 seconds and then remain on
solid, and the EVIC will display a “Service Tire Pres-
sure Monitoring System” message and dashes (- -) in
place of the pressure value.
Once you repair or replace the original road tire and
reinstall it, the TPMS will update automatically. In addi-
tion, the “Tire Pressure Monitoring Telltale Light” will
turn off and the graphic in the EVIC will display a new
pressure value instead of dashes (- -), as long as no tire
pressure is below the low-pressure warning limit in any
of the four active road tires. The vehicle may need to be driven for up to 20 minutes above 15 mph (24 km/h) in
order for the TPMS to receive this information.
