Having problems with your 1999 Pontiac Grand Am GT ?
What is the sensor on the front of the throttle body on a 99 grand am
Its either a mass air flow sensor or a throttle position sensor(TPS) if it is on the side of the throttle body in-line with the butterfly it is a TPS. If it is inside the air intake tube it is a MAF sensor but those are usually either in the intake after the throttle body or in the intake tube right after the air filter
