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

Check

 PERFORMANCE ORDER

1. Check reliability of connection to the sensor of the electric socket. Estimate reliability of landing of plugs and a condition of an electrical wiring. In case of need make the corresponding recovery repair of a chain.

2. Make identification of an electrical wiring of the sensor (see an accompanying illustration).


Color of isolation of wires can vary depending on car model (see below).

3. The following color scale of an electrical wiring of the MAR sensor is characteristic of the Civic models:
   a) Yellow-red: food;
   b) Green-white: grounding;
   c) Red-green: a signal on ECM/PCM.
4. On the Integra 1994 and 1995 models of of the issue the following coding of an electrical wiring of the sensor is used:
   a) Yellow-red: food (B18B1 engines);
   b) Ochroleucous: food (B18C1 engines);
   c) White-yellow: grounding:
   d) Green-white: a signal on ECM/PCM.
5. Coloring of isolation of an electrical wiring of the MAR sensor for the Integra models since 1996 of the issue:
   a) Yellow-red: food;
   b) Red-green: signal;
   c) Green-white: grounding.
6. Disunite the electric socket of the sensor, without starting the engine, include ignition and measure tension between plugs of wires of food and grounding of the socket of an electrical wiring. The result of measurement has to make about 5 V, otherwise check a condition of an electrical wiring, execute necessary recovery repair.
7. Turn out fixing screws and remove the sensor from the throttle case (see an illustration above), without disconnecting from it an electrical wiring.
8. Connect the voltmeter between plugs of an alarm wire and wire of grounding (use the straightened office paper clip). At the included ignition (do not start the engine) create depression in the basis of the sensor throttle removed from the case. About increase in depth of depression alarm tension has to decrease (see the accompanying table), otherwise replace the sensor.

Depth of depression, mm of mercury.
