What temp sensors do what?

[Animal Mother]

As per the diagram below, what temp sensors perform what function?

[Flat on my back]

Eh...

its in the writing...

or


1.is the engine oil temps sensor...back to the aux gauge me thinks.

Hit s2central...loads of info.

1-Oil Temp - For dash gauge
3-Oil Pressure - Low pressure warning for dash light
4-Oil pressure - For dash gauge
5-Water Temp sensor - For dash gauge
6-Water Temp sensor - ?? (might be after run fan )
9-Water Temp sensor - For ecu

Thanks, exactly what I want. Need to know No.6 now.

Anyon want to add?

S2 Central is no fully operational ATM.

As above, but;

5. Is the temp switch for the aux water pump & stage 1 fan (turbo cooling).
6. Is a seal for the above, and No.9.
7. Is the MFTS.
8. Is a plug (possibly instead of No.9.)
9. Is indeed the temp sender for the ECU (and the temp gauge to some extent, on some models).

MFTS?

[PeteRR]

Thanks


MFTS?

Multi Function Temp Sender. The 4-pin (originally) sender unit that controls the temp gauge amounst other things.

Good point, 6 is a gasket isn't it

7. MTFS also functions as over temp alert switch for AAN, and Water Temp gauge sender on AAN.

9. Gives only the actual temp for AAN ECU.

One temp sender is not on that picture, automatic A/C has it's own sender in heater core hose.
