i can only say the hsv range has the sensor for the proper gauge in the centre it get the reading from "can" and i think the sensor is in the drivers side sump, i could only think that the rest would have the same sensor for the ecu to know but i could be wrong...
Here we go guys, this summary of some investigative work done a while back on the US thread. The sender you mention is oil pressure only.

"The sensor connected on the [driver] side of the oil pan is not an actual temp sensor.
LS3 oil temp is calculated on the [VE SS]. I speculate that there is a base profile of oil temp simply based on engine run time & RPM that makes up the majority of the oil temp calculation, and other sensors (AAT, ECT, other?) might make small adjustments to that base profile to determine the final calculated oil temp value.
The LS3 oil temp calculation in the [VE SS] does not accurately model oil temp with an air to oil cooler (can't say if it's accurate in stock form).
If you are serious about wanting to know your oil temp, you should add an actual temp sensor. To easily add a temp sensor to a stock engine, buy the LS1 or LS6 block off piece for the oil pan. It's similar to the LS3 piece, except that the LS1 & LS6 pieces have a threaded hole for a temp sensor. I've never found the GM p/n for this piece, but I did find an aftermarket one as an example: CBM-10820. It has multiple threaded holes, a single M12 x 1.5 and two 1/8 NPT. I have zero experience or knowledge of this piece or its fitment and have no affiliation to the manufacturer."
