The determined value must be equal to or greater than normal
atmospheric pressure.

ÿ 2. Temperature alarm;
(1) Remove the sensor from the motor and use a standard digital
multimeter to measure the resistance at the temperature sensor
input (see point (c) "Temperature sensor parameters" on page 123).
In the event of a significant deviation of the measured value from
the standard, replace the sensor.

(b) Operation: the sensing surface must be directed downwards, the sensor
must be installed at an angle of less than 60° between the longitudinal
and vertical axis.

pressure, replace the sensor.
(a) Checking the pressure sensor:
(1) Connect the diagnostic scanner, turn on the ignition, and use the
scanner to determine the atmospheric pressure, which should be
equal to normal atmospheric pressure. If readings differ significantly
from normal atmospheric
(2) Start the engine, wait until normal coolant temperature and normal
idle speed are reached. Use a diagnostic scanner to determine the
pressure.
