I'm having a really weird problem that just started yesterday when I took the Supra out for a quick spin with the exhaust silencer in to see if that helped my overboosting problem (thanks everyone who's been helping me with that!)
Whenever I push the gas/open the throttle, my check engine light comes on. When in diagnostic mode, the CEL blinks steadily (the no code blink) and reads a code 51 when I open the throttle, which should be normal right? The CEL stays off when the throttle is closed whether I'm in diagnostic mode or not.
My question is, why is the CEL registering a code 51 when it's not in diagnostic mode? I'm relatively sure it's normal for it to give a code 51 in diagnostic mode when the throttle is not closed, since that's what 51 means. But it also gives me the code when not in diagnostic mode...
