I have disabled the bugger a while ago (tube bypass) but I’m getting a code 56 again.
20 ohms ? 10 w ?
Hope you can help

Is it plugged in now?

Yes it is.
I have a scan tool
But I think there may be and old problem with bad conections
to the EGR. (codes 54 and 55 sometimes and the EGR tests fine)
I just wanted to put a resistor with the right value to fool the computer for the boost
One less problem to look at and I dont even use it.
Thanks!

Do you get the SES light only when decelerating?

When I clear the codes and start fresh, it seems to only go on when decelerating
But after a short period of time the 56 code stays on most of the time.

Will hard wire the egr wires soon , but I would like to take care of the boost first.
I will guess the boost is 20 to 30 ohms at 10 watts.

I would bet that the boost control solenoid is bad + a few other things on the same quad driver.
