Frequently Asked Questions
Can I clear this code without fixing it?
Yes, but it will return if the underlying issue isn't fixed. Clearing a code only tells you if the problem is permanent or intermittent.
Will this code fail an MOT?
Probably yes if the check engine light is on during the MOT. The MOT checks OBD readiness monitors since 2018.
