helo ECU-MAN, I'm driving a 1993 honda civic eg9 ferio, my cheklight is always on when I am driving and I have used your checklist and this is what i get, 1.(O2A-oxygen sensor #1)
3. (MAP-manifold absolute pressure sensor) 41.(Primary oxygen sensor heater)
43.(Fuel supply system)(PS 3. and 5. are they the same? as both are stated manifold absolute pressure sensor)
But before I had done these checks on the ECU, I had visited my mech and after checking it, he advise he advised me that I need to change a HondataS300. Please advise.
