Absolute pressure sensor operating principle
The sensitive element, enclosed in a plastic container, consists of a Wheatstone bridge stenciled on a very thin ceramic plate (diaphragm) installed on the lower part of an annular support.
The diaphragm separates two chambers: In the lower chamber, which is sealed, a vacuum has been created, whereas the upper chamber is in direct communication through piping with the measuring point.
When operating, the pressure that generates on the measuring point produces a mechanical action on the sensor G L D S K U D J P Z K L F K G H À H F W V W K X V Y D U \ L Q J W K H U H V L V W R U Y D O X H V
Since the power supply is constant (+5 V), the resistor variation causes an output voltage variation ( 9 ) L J ) which
is proportional to the pressure value.

The reference voltage is 5 Volts: Since the control unit input circuit has been designed as a voltage divider, the reference voltage is divided between a resistor in the control unit and the sensor itself.
As a result, the control unit is able to assess the sensor resistance variations through the voltage changes, thus receiving information on the temperature.
The air temperature sensor is incorporated with the absolute pressure sensor: a single sensor with two functions.

The sensor (one on each cylinder bank) is installed on the coolant collecting body ( ) L J ) from heads, just behind
the thermostat.
It has a brass body that protects the actual resistive element, which consists of an NTC thermistor (Negative

The reference voltage is 5 Volts: Since the control unit input circuit has been designed as a voltage divider, the reference voltage is divided between a resistor in the control unit and the sensor itself.
As a result, the control unit is able to assess the sensor resistance variations through the voltage changes, thus receiving information on the temperature.

The electronic control unit governs and activates the various airbag modules. The ECU contains following parts: • an aluminum container in which the following are arranged:
• an electromechanical sensor which discriminates the “activation/deactivation” conditions according to vehicle
deceleration;
• an electromagnetic safety sensor operating with the electromechanical sensor; both sensors must enable the
“activation” condition for the system to be deployed;
• an electronic board that analyses the signals from the two sensors and deploys the airbag modules when
required.
Furthermore, the electronic board has self-diagnostic features. When the ignition key is turned to “MAR”, it checks
the correct operation of the entire system. During the test a red warning light on the dashboard turns on. The
warning light turns off approximately four seconds after the engine is started if the system is working correctly. The airbag system will need to be attended to at an authorized workshop if either the red airbag warning light on the dashboard stays on for longer than 4-6 seconds after the engine has been started or turns on while traveling.

•Disconnect the ground cable from the battery negative terminal before removing electronic components (carry out the operation on the battery disconnect inside the engine);
• electrical measurements on electronic components must be carried out only with adequate measuring equipment;
• make sure that electronic device cables (length, type of conductor, positioning, clamping, shielding continuity
where required, grounding, etc.) are correct for the system and that have been carefully restored to the original condition after service;
• never insert or remove the connector from the electronic control units while powered;
• in case of temperatures over 80°C (drying ovens) remove the electronic control units;
• when making connections, tighten the connector nuts (temperature, pressure sensors etc.) to the prescribed
torque ;
• electronic control unit measuring at plugs, plug connections and electrical connections of components are to be
carried out only using the appropriate equipment; never use improper tools such as metal wires, screwdrivers,
clips or suchlike; besides the danger of short circuits, these methods could damage the plug connections and subsequently cause contact problems.
