I have a Honda CRV throwing the U0401-68 code. About a week ago was driving and my check engine light started blinking. I got it to a shop were they replaced ignition coil #1 and all 4 spark plugs. Everything was good. Fast forward to last night same thing happened I was able to change the 3 other coils and started down the road and then my dashboard lit up like a Christmas tree all systems down. I pulled over and had my car towed to my local shop were they said U0401-68 code, possible crankshaft.... Anyone have ideas on what this issue is?
