What does this error code on my 1998 Tiburon mean? PO103 MAF/VAF circuit high input

Hello oceanbreez
It can mean that the mass air flow sensor is bad or you have a vacum
leak. The sensor is on the air intake tube that runs from the intake
manifold on top of the engine to the air filter housing. Check for any vacum leaks going into and in the area of the sensor, such as the clamps on the intake tube and be sure the air filter housing cover is
on correctly and secure, also check the electrical connections at the
sensor make sure they are clean and tight. Also when checking for a
vacum leak a can of spray gumout can be helpfull, just spray the area
in question, if the engine revs up a little a leak is present. If all this
checks out I would replace the mass air flow sensor. But if the car is
running good you can have the code cleared at any parts store for free
then drive it normaly and see if the code pops again, if the engine light
comes on again refer to the above, if not could be just one of those
things. Hope this helps.
