Title: WHERE CAN I FIND THE TEMP GAUGE SENDER
Post by: Miggy24 on 05 January 2010, 21:01:03

Hello can anyone please tell me where the temp gauge sender is and best way to replace it

Its right at the back of the engine, below and between the DIS (2) and EGR (1).  Haynes has a diagram:

I've got a photo of it somewhere on here, but can't find it just now.  Will look on photobucket in a mo.

Access isn't nice, possibly easier from below if you can get the car up on ramps.

Here you go:

I think (looking at Haynes wiring diags) that it's a blue wire, 0.75mm². Seem to remember it has a rectangular black plastic housing at the end, within which is a quarter-inch spade receptacle.  One side of the housing is cut away so it can slide onto the sender like this:

Note, this image shows only how the connection is made, not the real connector/housing.

Find the wire to the ECU sensor temp sensor shown in the picture above and follow it back to where it joins the main conduit.......you should then be able to find the single lone wire for the gauge sensor exiting the same part of conduit.

Fault in the cable or knackered sender unit

I  think the single wire sensor operates the dash gauge and the sensor with the rectangular plug gives readings to the ECU.

I didn't think there was any electrical link between the two :-/

Im thinking that the rectangular plug (or the wires to it) must have been disturbed to bring up the error code.

Good point, well made.
Gauge sensor doesn't talk to ECU at all AFAIK, so can't throw fault codes.

Does the gauge now work correctly?

Hi yes the gauge works fine now

Give the connector a wiggle on the coolant sensor for the ecu (the one with the light blue connector in the photo)
