NOTE:
For diagnostics purposes, use Vehicle
Communication Kit (VCK). See DIAGNOSTIC
PROCEDURES subsection.
After a problem has been solved, ensure to clear
the fault(s) in the EMS ECU using the VCK. Refer
to DIAGNOSTIC PROCEDURES subsection.
Resistance Measurement
When measuring the resistance with an ohmmeter,
all values are given for a temperature of 20°C
(69°F). The value of a resistance varies with the
temperature. The resistance value for usual resis-
tor or windings (such as injectors)
increases
as
the temperature increases. However, our temper-
ature sensors are NTC types (Negative Tempera-
ture Coefficient) and work the opposite which
means that the resistance value
decreases
as the
temperature increases. Take it into account when
measuring at temperatures different from 20°C
(69°F). Use this table for resistance variation rela-
tive to temperature for
temperature
sensors.
CONVERSION CHART FOR TEMPERATURE SENSORS
The resistance value of a temperature sensor may
test good at a certain temperature but it might be
defective at other temperatures. If in doubt, try a
new sensor.
Also remember this validates the operation of the
sensor at ambient temperature. It does not vali-
date the over temperature functionality. To test it,
the sensor could be removed from the engine/
muffler and heated with a heat gun while it is still
connected to the harness to see if the EMS ECU
will detect the high temperature condition and
generate a fault code.
NOTE:
In case of overheating, EGT and CTS do
not generate fault codes. A message will be dis-
played on the information center, the beeper will
be activated and the EMS will be set in limp home
mode.
