Check of serviceability of a condition and replacement of the sensor of absolute pressure in the pipeline (MAR)

CHECK

 PERFORMANCE ORDER

1. The MAR sensor traces variations of depth of depression in the inlet pipeline, connected with changes of turns of a cranked shaft and the current load of the engine, and will transform received information to a peak signal. RSM uses information arriving from the MAR sensor at correction of installations of a corner of an advancing of ignition. The amplitude of a signal developed by the sensor can change in limits from 1.0 ÷ 1.5 In at completely closed butterfly valve (deep depression) to 4.0 ÷ 4.5 In at completely open zaslonka (weak depression) and can vary slightly depending on car height above sea level. The MAR sensor is fixed on the throttle case, its refusals lead to record in memory of system of self-diagnostics of a code of malfunction Р0107 or Р0108.

2. Measure size of the basic tension submitted on the sensor from RSM. Disunite the socket of electroconducting and connect the voltmeter between REF plugs (+) and GND (-) the socket. At the included ignition the device should register about 5.0 V.Otsutstviye's indication of a basic signal speaks about break in a chain of RSM or about failure actually the module.

3. Check alarm tension of the sensor at the muffled engine connect the voltmeter between SIG plugs (+) and GND (-) the sensor socket. At the included ignition the amplitude of a signal should lie within a range of 2.5 ÷ 3.5 Century.
4. Now it is necessary to check serviceability of functioning of the sensor at the working power unit. Start the engine and observe behind voltmeter indications in process of increase in turns of the engine from the single. The amplitude of a signal should accrue on decrease in depth of depression. On single turns depth of depression is maximum and alarm tension should not rise above 0.5 ÷ 1.5 Century in process of increase in turns depth of depression falls that should conduct to decrease in amplitude of a measured signal.

Change of depth of depression in the inlet pipeline can be tracked by means of the vacuum gage. At completely open zaslonka pressure in the pipeline can be compared to the atmospheric. More detailed information on vacuum checks is provided in the Part the General and major maintenance of the engine of Head the Engine.

5. At negative results of check replace the sensor.

REPLACEMENT

 PERFORMANCE ORDER

1. Disconnect a negative wire from the battery.

If the stereosystem established on the car is equipped with a security code before disconnecting the battery make sure that have the correct combination for audiosystem input in action!

2. Disconnect electroconducting from the MAR sensor.

3. Turn out fixing screws and remove the sensor from the throttle case.

4. Installation is made upside-down.
