After you opened the first time the hood, you saw a lot of wires, sensors, connectors. You may afraid of future work. But do not be afraid, Ill try to explain what the sensor is on the intake manifold, throttle, as well as their characteristics in engines D14 and D14.



Manifold Absolute Pressure — Sensor intake manifold, aka MAF. Often met with as on the bottom image, sensor the same fixtures and parameters on many Honda models. Located on throttle — from above.
The range of measured pressure in the intake manifold 10 to 170 kPa. The band issued the values shown in the table (there are versions with dimensions from 400 to 4770 mV).
When the location of the key top, the order of the wires: 1 - Power, 2 - Ground, 3 - Signal.\nTotal: 3 wires.

Throttle Position Sensor — position sensor throttle, monitors the degree of opening. Full opening, full closing, quarter, eighth part, etc. has 3 contacts, fastened with studs to the throttle body at the level of the axis of rotation. The black sensor on the side of the throttle.
Summary: 3 wire, powered by 5 volts.



Intake Air Temperature — air temperature sensor in the intake tract. Two-pin sensor for measuring the air temperature in the intake tract due to its dimensions, the control unit ECU makes a performance in idle mode. Is attached or in the box of the filter or in the intake tube. The values are the same as on TA.

\nAir Temperature-the air temperature Sensor. Also the sensor in the intake manifold, but outdated version of measuring air temperature, the polarity doesnt matter in the different models used the same. Attached at the rear bottom of the intake manifold with 2 screws. The screws are usually zakislenna, hats cut with a Dremel. Can be changed with different Honda models.\nSummary: 2 wires, polarity is not important.

Injector injector

the Atomizer, in the engines of motor D set 4 pieces, for each cylinder 1 injector. Required to atomize the fuel under high pressure. Due to the current in the winding, the core opens or closes the channel. The resistance of each injector — is different, so be careful. There were cases of incorrect installation of the injectors, and burned part of the ECU. More details in the article. All four injectors, one contact is connected to the splitter. According to another contact, passes the signal to the injector.
Summary: 4 injectors = 8 wires, 4 signal and 1 General — food.
