Question

I am facing this issue from 2 months now some mechanic says its engine fault I don't know what to do

Answer 1

P3400 VPS (variable pause system) stuck off Bank 1

This can be engine fault due to low oil or low oil pressure, Low oil level below the minimum can cause either  of the VPS switch to set a P3400 code or a P3497. The problem is mainly with the rocker arm oil pressure switch and this  VPS are common code condition with  Honda, Replace the rocker arm oil pressure switch on Bank 1 and clear the code.
