So the other day I go to start my 2010 Tsx 2.5L model...it only cranked so I stopped. Then tried again and it started up...then immediately threw a check engine and emission system malfunction on the dash.
I tried to drive down the street but as soon as I tried giving any gas it just wouldn't develop any power and you could hear the engine running rough and the check engine started blinking so I immediately took back home and turned off.
I got a scanner and it threw the p1659 ETCS relay malfunction and misfire on #2. I've been trying forever to find out where the ETCS fuse and relay are located but have had no luck.
Can anyone help me with the location of the ETCS relay and/or give me any knowledge about if it's not the relay and something else from the symptoms I provided.
I actually read someones post somewhere who explained the exact issue I had literally word for word but no one really gave any good info but as it happened like mine I think it's a common failure for this series of TSX so I imagine someone has heard of what causes it.
Any help you can provide would be super appreciated! Let me know if you need any more info.

 

Sorry I meant 2.4 L lol I knew someone would correct me

 

Alright nevermind...turns out that the ETCS code was just a byproduct of the misfire on cylinder #2...which was due to a bad coil.
Therefore, if your driving any Acura or Honda in this year range and you try and start your car it won't. Then try again and it does but you get a check engine light and emission check on your dash. And upon trying to drive your car won't develop any power and then gets blinking check engine...
Check your coils first as it's likely one of those.
