What does ” below threshold 1 ” mean on P2002?
Edit – While P2002 code says “Particulate Trap Efficiency below threshold 1” As far as i know, im not sure if 1 means the bottom sensor or the top. But if the statement says “Below Efficiency” That is telling me there is a leak somewhere and the most common part to cause a leak on any exhaust system is a flex pipe.
