Grey tank level sensor

[JVR]

2006 Essex 4508

Anyone know where the sensor is located and how to access or test it?
Mine doesn't read and the sensor is $800.
Thanks,
JVR

Hi JVR,
On an ESSEX, I do not know. However, on my coach the sensors are located behind the exterior entertainment center. Because one must remove the entertainment center to get to the sensors, it is a real PITA. The other, place would be behind the utility bay wall which has all the water and sewer connections. If there, it would be another you know what to get to the sensors.

Keepin tank level monitors working, is generally a non stop battle. IMO there are two choices, do as I do and just forget about it, or install external tank monitors (pricey but they stay working). Wish I had better news for ya'.

I have used this product a couple of times over the last few years with good success. Use as directed and your sensors will come back to life.
