Whats this on my 940 turbo?

I found this tube and it's damaged. The other end had a screw bodged in the end. Picture located bulk head end of engine in the middle above rocker. Goes left to right and ends up UK passenger side.

Definitely looks like a vacuum tube. As mentioned, dashboard boost gauge feed?

is your with cruise control?

thanks all. I do not have cruise control or a turbo gauge. I suspect it's for a turbo gauge but none here apart from what the old user fitted and that's using a different line.

Next thing is to follow the hose to its ends to find out if it's actually connected to anything. A thought crossed my mind that if the previous owner had a boost gauge, he also had an MBC so the gauge would have been on one hose and the MBC on the other - the one in your pictures maybe.

I have a turbo smart valve. I can switch between 10 and 16psi. I'm just confused why i have (looks to be) a volvo boost line and no OEM guage.
Unless... Does the volvo ECU come with a MAP sensor? My modded 480 turbo had a remapped ecu with a 3 bar map sensor added. oh the fun of 25psi on a T25 and FWD. Shame the autobox was not friends lol. |
If yours is/was an LPT originally, it won't have the boost gauge as far as i understand things.
The MAF takes the place of a MAP sensor usually, the MAP tends to eliminate the need for a MAF as the same info can be calculated by the ECU from engine speed, throttle position (through a throttle potentiometer, rather than just two switches as on the majority of the Volvo systems) and Manifold Absolute Pressure. ;) :D |
