Still throwing same code

no the code is still there. Runs great hsve learned to love with it

 

Maybe it's me. My wife always says it's me. But isn't P0355 and IGNITION code for the 5th cylinder?

 

This

 

was a couple years ago now but I remember it saying crankshaft. Would have to scan again and see. But I have changed spark plugs since then maybe even twice

 

Just Googling P0355 and Toyota brings up a lot of links essentially saying this (but I don't know if Taco codes are different). So it's a more direct code for the coil (versus 'misfire'):

 

Remove both battery cables touch both together for a few seconds.

 

Make sure you put a new ignition coil in cylinder 5 not cylinder 6. I changed the spark plugs and then deleted the CEL with a scanner. Problem never came back

 

P0355 means the ECM isn't receiving an ignition confirmation (IGF) signal from the #5 ignition coil, usually it will disable the fuel injector in that cylinder to protect the converter for the ignition cycle or until the fault clears.
