Engine Oil Temperature Sender

Hi all...
I have a 2007 LR3 with Ford Cologne 4.0L gasoline (petrol) V6 and am attempting to find out as much as I can about the engine oil temperature (EOT) sensor/sender, which on my machine is located in the sump (ladder rail) on the driver's side of the engine. When I replaced the engine I noted a number "4L3A12A648AB" on the original sender but I can't seem to locate any EOT sensor with that number. I am able to find many for the 5.4 V8 Ford "4L3Z12A648AA/AB" but am unsure if they are the same, trying to run down an intermittent starting problem. Any extra information anyone has on the EOT sensor/sender would be appreciated, thanks in advance...

Edit: 1030AM Strike out "Explorer" and insert "Expedition" and "F150"
Edit: 1500; RESOLVED (mostly) This appears to be an exact duplicate part for a Ford DY1025 or it's many substitute cousins, like the Standard Motor Parts TX131 or the WVE 5S7291 and the 4L3Z12A648AA/AB, please find attached a pdf file courtesy of WVE showing dimensions and thread sizes, when I finally get hold of one I'll be sure to update with some resistance measurements, etc.

Don't hold your breath on it fixing your issue. One of my wires was severed after reinstalling the engine and it would start and drive but sent everything to limp mode as the oil temp is a backup for the coolant temp sensor. I had a similar intermittent start issue and it was the starter.

This has only happened once, but got a P0196 Oil temperature sensor Range/performance after the intermittent start condition, so looking for information on this unusual condition, has not happened again but better safe than sorry. I did recheck the starter motor connections, thanks for the heads up, in Land Rover land I'll not be holding my breath...
