i'm sure this has been asked before, but i couldn't find it.

will a faulty tps cause the car to hit fuel cut?
from what i understand, the car measures the amount of air flow and the throttle position against preset limits. my tps is set at .5 volts closed, but won't go past 3.xx volts wide open. from what i've read, it should read between 4.5 and 5 volts wide open. my thinking is that if the air coming in doesn't match the throttle position the car will hit fuel cut.
i may be way off on this, which is why i'm asking for help.
