3B multisensorin johtojen värit

[juhakill]

Eli eli, aikoinaan vuoti tuo sensori ja nyt sitten jäi kaksi johtoa "käteen" niistä. Onko kellään muistikuvaa tai muuta tietoa miten eri väriset johdot asettuvat anturiin?? Joo,ja tiedän, olisi pitänyt tarkistaa johdot paremmin anturin juuresta kun oli kansi irti, pikkasen olisi ollut enemmän tilaa.

SJM kunniaan eli sieltä lainattua:


As mentioned, this sending unit can have 3 or 4 terminal connections, the original sensor had 4 terminals and used +12V on terminal 3/+ and was made by VDO. These 4 terminal sensors would most often fail by not providing a signal for the coolant temperature gauge.

There is also a replacement sensor that uses only 3 terminals and eliminates the need for the +12V terminal connection and are made by Behr. I have found that some of these 3 terminal sensors have failed over time with a false overheat warning signal.

Other things to note: (5000T/Q, 200TQ) Fuse #12 supplies +12V to the Multi-Function Temperature sensor on the original 4 terminal sensors, so check your fuses. This fuse #12 also supplies +12V to the back up lights and to the speedometer sending unit in the transmission. S4/S6, check the Bentley Wiring diagrams for the correct fuse.

If you ground terminal 1/T (BR/Y wire), the coolant temp. gauge on the dash should go to a max temp reading with the ign. key on. Testing Other Functions of this Sensor This sending unit also provides a ground signal to the Engine Control Unit (1986-88 Audi 5000T/5000TQ and 1989-91 200T/200TQ) if the engine is running too hot (over 247F, 119C) which will reduce the amount of boost the ECU will provide.

The 1992-95 Audi S4/S6 Engine Control Unit (ECU) does not use this overtemp signal from this Multi-Function Temperature Sensor. The Terminal 2/R connection (Blue wire with green stripe) wire coming from this sending unit should be tested to ensure that it is not grounded.

If you remove the connector from the sending unit and look at it with the notch at the top, terminal 3 is at the upper LEFT, terminal 4 is at the upper RIGHT, terminal 2 is at the lower RIGHT, and terminal 1 is at the lower LEFT.

Eiköhä tolla alkuun pääse?

Juu,kiitos,kiitos. Jäihän sinne kaksi johtoa vielä avuiksikin kiinni.
