What is the sensor back by cylinder 1

[nkemp]

When you remove the intake manifold, there is a sensor on the back of the engine per this picture... it is the one connected to the single green wire:

19406
It does not look like a ground point.

What is it? Is it used in our car?

it is attached to a solid green wire. Where does that come out?

Just curious,

Nick

I think that's for engine temperature.

Sender for the dash temp gauge. Other end of the wire is where they all go - on the bulkhead connector and then to the gauge.

I thought the engine temperature sensor was off the coolant lines under the intake manifold. One of the two located in the Y pipe.

There are two electrical sensors in the y-pipe. The two-wire sensor is for the idle ECU (higher idle speed when very cold). The one-wire sensor is for the Lambda ECU for cold temperature enrichment.

There is also a vacuum switch in the y-pipe that switches between cold vacuum enrichment and ignition vacuum advance.

There is also a temp switch in the left side water pipe that turn the fans on, popularly called the otterstat for no particular reason. Every other car in the world calls that the cooling fan switch. .. .

The schematic I have spells it "Outerstat"

Otterstat = Oughta-be-on stat. I think it is a medical term :-)

Thanks for clearing up the sensor question.

I thought it was the manufacturers name

Do you mean manufacturers Trade name? The MFGR of these originally was Bosch. I think VDO also makes them but don't hold me to that.

The schematic I have spells it "Outerstat"
FWIW: The workshop Manual calls it "FAN SWITCH (OTTERSTAT SWITCH)" at M:15:01, and "OTTERSTAT" on the schematic at M:18:10

popularly called the otterstat for no particular reason.

Other cars have an "otter switch," also. Otter is the name of the company in the UK that originated the switch (http://www.ottercontrols.co.uk/about/history).
