Like the title stated I accidentally left the cam position sensor A unplugged (passenger side on valve cover) and started the car, it started up normal, once I noticed it was unplugged I turned off the engine and plugged it back in. Could this have caused any damage?

Were the cams removed or timing possibly misaligned?

The ECU probably would have panicked in regards to timing and thrown a CEL, but if you didn't drive it then you're probably fine, so long as you're not hearing any bad noises. We've had a faulty crank position sensor on a K24 and it throws a CEL, but I guess it hasn't done any damage because the car survived the dyno

If you just idled the car then you're fine.

You'd just get a misfire if you had actually driven the car, as ignition timing would be off by the ECU. Would have been a problem if you had ran the car hard afterwards or left it unplugged for a long time, but definitely no harm if you just idled it.

Thanks for the reply guys, yea the car was only idling.
