Technical P0638 Error Code

[Normy19]

Hello,

I had the check engine message beep at me about a week ago when I started the car with the triangle lit up and I’ve got a cheap error reader that’s found P0638. It was only there for that day and it’s not came back since. Car drives completely normal. Is it anything to worry about? Thanks.

Probably throttle related..

If only appears on occasions.. just keep up with routine servicing
