What is the sensor that is on the driver's side, has a heatshield and right in front of the y-pipe

 

See attached: are you talking about something mounted to transfer case (vehicle speed sensor), etc.?

 

Nope..its the sensor where the ypipe and the exhaust mani meet up by the engine..there is a sensor there....im trying to find out which sensor is causing my water crossing issue

Also...another question..what is the sensor on the left bottom side of the water pump?

 

Probably crank sensor

Probably cam sensor

 

Crank sensor is under(somewhat) the water pump.

editDamn...I was wrong...Cam sensor is under the water pump.

 

Cam sensor is below the water pump on the engine cover. The crank sensor is on the drivers side about where the starter is on the passenger side. The cover is a pita to remove when the left exhaust manifold is in place. It's a pair of 6 or 7 mm bolts of differing length that hold the assembly in place.

 

I think that is whats getting wet (cam sensor) and giving me idle issues after water crossing...because now think of it..when I changed out my thermostat...i got antifreeze all over the water pump...when I cranked the engine..it started to do the same erratic idling as when I cross water...BINGO

 

Make sure the wiring is in good shape. Clean everything up, including the sensor itself. You don't want to know how much a new one is going for these days. Thanks to Ford destroying so many of the Land Rover legacy parts, the last time I checked, I could buy a DI for less than the cost of a CPS new.
