Code 6 on b20b swap help
 

I'm using a b18a1 ecu and I'm getting a code 6. I've already tried getting a new thermostat. That didn't work. Swaped into an ef sedan if it makes any difference.

Note I'm not very good with cars but I'm trying to learn so explain things to me like if I was 12 years old.

Does it run?

Yeah. It's drivable just need to make that check engine light go away for emissions.

Number 12 hooked up or it may need to be replaced.

Re-live the Vtec experience. Calling all vtecs.

That's been replaced. I should also mention that this has been a problem since the motor swap was finished. I was told by one person that I need to wire the thermometer directly to the ecu and told that I had the wrong harness by a different person.

its most likely broken wiring as this problem is common on ef's
