98 v70 GLT ECU "not ready". Can't pass inspection

[ToriWhite]

99% of the time the monitors don't go ready because of faults in the system, so the minute they go ready the CEL will come on. People get frustrated throwing parts instead of diagnosing with equipment. You can't fix these cars with a screwdriver anymore, thats the price for a precision piece of machinery.

"Congrats, after you've been pulling your hair out driving like a maniac for a week- you've got all your readiness monitors checked! Oh, also the CEL, time to replace your O2 sensors and do it all again..."
That's a comforting thought, thanks Abs

My Evap would take over 2000 miles to go ready and then , about 1/4 times, pop a P0455 code

I finally found a tiny crack in the J hose, about 100 um , which, in replacement , solved both.

Evap monitor now sets in 50 miles

The P2 air pump and pressure system is much more robust

hasn't one of the tuners come up with a fake readiness status yet? I am pro environment, but as long as the tailpipe emissions are within spec I don't see too much harm done.

Glad we just have tailpipe emission check here. All of my 850ies never had problems passing so far.

In TunerPro under Emissions you can set the required number of trip cycles to 0, it only tweaks the readiness count. For m4.4 turbo ECM. Get a modded ECM just for inspection time.

I've never tested this myself, no emissions inspection here.
