Just had a lot of rain and drove thru 1ft-2ft of water yesterday, now before engine even turns over, (key position 2) the trans temp light comes on... on a cold cold engine?

So where is the sensor(s) located to check connection and replace if need be?

Thanks all...

 

 

Just had the radiator out on my Disco and it would be near impossible to remove this sensor without unbolting and pulling up the radiator. The cooler is infront of the radiator and as stated it is on the passenger side.

 

Good to see you guys on board and appreciate your comments/replys.

 

Thanks for the replies so far, here comes an innocent question, Is this type of sensor affected by immersion in water. In other words could this thing dry out and function properly if indeed this is the reason for the fault light?

 

There is also another temp sensor located on the back of the transmission (driver's side). Easy to get to and may have been affected if you were in deep water. Try unplugging it and see if your light goes out. I would start there first as the one on the cooler is a bit harder to get at.

Great! Thanks. Now that I know where they both are, what do they look like. I know novice question.

 

Here's the one that goes to the trans cooler: Sender Oil Cooler Temperature Transmission | Land Rover Electrical Parts, Batteries, Relays, Lamps & More
That bracket you see bolts on near the top of the radiator (passenger side) You can follow the wiring harness down to the bottom of the cooler where it screws in. The one on the rear of the transmission (drivers side) is easy. Slide underneath your D2 and look at the side of the trans toward the back. You will see 2 wires that plug into the sensor.

Thank you. Cant wait to crawl under and test the easy one first, in the morning we will know if it is going to be a simple or tough fix.

 

Just unplug it. If the light is still on then it's probably the sensor on the front. If it's the front, do NOT go by the RAVE manual. They want you to rip the whole front end apart to get it out. There's a shortcut to it that will take about 20-30 mins. You can do a search for the procedure. (someone else on here told me how to do it so I know it's on here )
But always start with the easy one first!
