9 months ago, I used an Actron scanner to detect the crankshaft sensor code, which I replaced successfully. The car has been running great ever since. I recently went to smog it and they said the OBD would not link to their scanner so it can't be smogged until I fix it. My Actron is also now showing "link error." The strange thing is that it does link at times, but usually it won't. It did link the night I returned from a 100 mile trip, and again the next morning. But when I drove it straight to the smog station it was already reading "link error" (both on my Actron and on the smog guy's scanner) when I got there. Can't figure out the off again on again problem. The few times it has linked, it reads all the smog IM's "ready" and shows no repair codes.
