Sensor location for Fuel Filter on CM-870?

[Waterloo]

That is the question... Where is the sensor located for the fuel filter on the CM-870, asking for a friend. This is in a 2006/7 Volvo VNL 6...

What sensor are you talking about? The fuel pressure sensor is located on the ifsm same as your cm871. A WIF sensor is usually on the davco. But as for a specific fuel filter sensor?? I'm not even sure what that is or what it would sense.

Waterloo the only fuel filter sensor i know of on a Volvo is the WIF, water-in-fuel sensor and when it fails, (or if it detects water), it throws a very annoying dash icon on the volvo screen.

Like Chamber said: "on the Davco".

Or Raycor, many Volvos run a Raycor fuel water seperator. It is usually outboard at the front of the passenger side frame rail. The sensor is in the plastic bowl on the bottom. The Volvo factory wiring to it often gets brittle and breaks because they zip tie it so tight and don't really give enough wire to begin with. Other then that there is a diode in the Raycor WIF sensor that goes bad. They are color coordinated so make sure if he replaces it to get the same color sensor body as the one he takes out or the Volvo ECM will not recognize it. (mine is Blue on a 2012)
