Help With RKE P0039 Code
Well, my ongoing turbo install has taken a rather strange turn...
I started a thread earlier in the EMS section of this forum trying to narrow down a problem I'm encountering with the transition to boost. The problem is right at 00 inHg, the car begins to jerk rather violently and then the AFR goes incredibly rich. I checked the spark plug function with a timing light and all is in order, the Interceptor actually seems to be doing its job rather well, as part throttle driving is perfect, the grounds for the ignition set are all correct, as is the other wiring. Despite all this, the car still behaved the same, with the horrendous bucking at the transition to boost.
I had received a CEL and I checked it with a scanner to find the RKE P0039 code, which, from what I've found on this site, is either a generic "Supercharger/Turbocharger" code or a Secondary Shutter Valve malfunction. However, that's all that I can glean from RX8club's forums. Does anyone know how to remedy the situation? I am curious if the addition of positive pressure to the intake manifold is the culprit here, but if this is the case, why haven't I heard of this more often on RX-8 turbocharger installs? (outside of the debate over the Greddy block-off plate for the SSV and its usefulness)
Any help would be greatly appreciated, as after many weeks (and many tribulations) my RX-8 still sits in the garage gathering dust... sigh...

could not help you with the 00039 code as it does not show up in the mazda charts.
good luck.

I just had this CEL today. p0039 along with a p0103
I'm thinking coils. I jammed on the throttle when it happened.
I was data logging at the time, so will be able to check out the logs later tonight when I get home.

I guess that's sort of good news - I noticed that part of my APV motor was exposed to some pretty high heat, as there's some melted plastic. Possibly a problem with this set of valves opening?
However, ignition could be the problem - are you using an upgraded set?

oem coils. NA engine. I really shouldn't have any engine issues at this point and I know the hardware should be functional, since the engine was taken apart and rebuilt from scratch about 5k miles ago.

Don't know, but all the 003x's seem to be related to the O2 sensors, so that's a good bet and
I believe it will be the rear.

Scanalyser is oblivious to it and I never pushed Cobb further... I was just happy for the visible CELs to go away... it was a pain in the a$$ to hard reset my ECU (battery terminal pull) every time I flashed a new map.

just discovered this on Scremn8's car. N/A, 6 port.
Strange.
Jeff, let us know what Cobb says about it.
