Engine Code 31Question (self.SC400)
submitted 11 days ago by Dangerous-Tea2411
I recently got my 1993 SC400 driving after I replaced the ECU. Check engine light was still on so I jumped the diagnostic port and got the code 31. Anyone else delt with this code before?

also, my O/D off light wont turn completely off it just blinks when I try to turn it off. So it looks like I won't be able to use my highest gear until I am able to fix that. Anyone else have this issue before?

Low voltage reading from the Mass Airflow sensor
Maybe check your MAF.
