My defi boost guage does not register boost at start up this morning. The red light is blinking so I know it has power. I checked all connections at the turbo and the controller. I haven't pulled the guage, but since it has power, I imagine that will not be the issue.
Any thoughts?

Try turning the boost up until it registers on the gauge.

Cheap digital crap...
![]() But seriously.. Pull the sender and check it and the line for blockage. Use a pump or something to generate pressure on it and see it it works. Senders fail much more often than guages.

How are Defi guages? I was looking into this set up (see link).

Defi gauges are great IMO.
Tyson has that setup in his Evo.

If it is the sender (I am assuming this is the wire from the control unit to the guage), where can you get replacements?

I believe they import all the Defi stuff into the US. I had to call them once for an EGT sensor, they shipped it out to me the same day. |

If the gauge display performs the sweep correctly during power on, then the display is working fine (that's the point of the sweep test). If the control unit is not receiving data from the sensor for a particular gauge, the gauge blinks the warning light to tell you there's an issue with the sender. This means the problem is with the pressure sender under the hood, or with the wire connecting that sender to the control unit. If the sensor is busted, here's the part you need: http://shop.edoperformance.com/produ...bce5531fa3e128 But check to make sure the wire isn't just unplugged or cut or something, since that's an easy and cheap fix.

And as I said, the senders can get clogged, or gunked up... they should be oriented on the sides or above the hose is best so they don't, but can anyway.
Below the hose is worst. Check the wiring as Scottr usggested between teh sender and controller, and then check the sender itself.

Thanks for the beer. Any luck getting the sender unit open? The wife took Subaru company much better then I thought. We'll have to do it again soon. I'm going to look into a pair of boots on my days off and then I'll be off to the bunny slope.

Yesterday at Dereks house, we found the problem easily. I don't know how I didn't see it the first time I checked, because it took all of 10 seconds to see the problem last night. A squirrel had climbed into the engine compartment and selectively cut both the red tube from the manifold to the sensor and the black wire from the sensor to the control unit. The little bugger cut the black wire only 1/4" from the sensor. With a little patience today I was able to get enough wire exposed to splice it back together. He also cut the red tube right at the sensor so they reconnected easily. Squirrels!

My oil pressure sensor started doing the same thing except it works fine when everything is cold. A few minutes afterwards it dies.

So this morning I decide to check under the hood and make sure the sensor to the guage is in a nice dry location. I open the hood and all looks nice and cozy including the rabbit that is staring up at me with a look of "shut the f'n door!"
The funny part was I scared it, so it ran down the downpipe under the car. I think it went on top of my aluminum skid plate because there were no tracks leaving the car. So this thing has been living in my car now for two weeks. Any thoughts other than ritually peeing in a circle around my car every night?
