Re: Dash temperature gauge


dave_king_ev
 

Something is wrong with Dave's summary. A 4-wire sensor for the
after-run pump? Wny? All it needs is an on/off switch, which would
mean two-wire, not four.

Dave, are you looking at wiring diagrams or are you relying on catalog
descriptions of the devices?

And the new green d-shaped (oval) sensor did the trick.

The dash gauge is now working.

Another note, I think the AC was not working while this sensor was
malfunctioning. It seems to be working now. I'm not sure if this is
related.

So to sum up ...

There are two sensors under the engine in the thermostat housing.
You'll have to drop the belly pan to get to these, they are on the
driver's side.

The 4-pin d-shaped (oval) is for the dash gauge and the fuel
injection. The new sensor is green, the original one was black. the
black ones are a known problem.

The 4-pin square sensor next to the d-shaped sensor is for the fans.

There is a 4-pin blue sensor in a hose near the top of the block that
is for the after-run pumps.

Each sensor is held in with a c-clip. Each sensor has a rubber o-ring.

It is possible to swap out the sensors without draining the coolant
system, but you need to be quick with the lower ones (make sure the
coolant is cold, safety goggles and a closed mouth are advised)

The o-ring does not always come out when you pull the sensor. Make
sure it is accounted for before replacing the c-clip. Also be sure
the sensor is under the c-clip not over it, or it will pop out and
drain all your coolant.

Sensors and o-rings are available from Steve at


Thanks All !!

Dave

Dave is correct with regard to the green oval plug sensor. The
function
was mislabeled on the webstore.
I have since corrected the dual function switch to read.....For fuel
injection and temperature gauge.
The square plug sensor is the sensor that controls the two cooling
fans.

On your 2002, the D-shaped 4-pin sensor is used to signal the ECU
(engine control) and the temperature gauge on the dash.
There was a discussion about this on vortex recently.

Note that the europarts catalog says the new green sensor is for
"fuel
injection and cooling fans" but that's wrong.

Carl is right: the new sensor is for the fuel injection and the
GAUGE, not the fans as europarts states.
