hey guys wats a TPS and a o2 sensor

TPS = Throttle position sensor, its mounted to the front of your throttle and tells the engine computer how far your foot is to the floor.

The 02 sensor is the oxygen sensor and is bolted to the exhaust manifold just above the cat convertor. It tells the engine computer how much unburnt oxygen is in the exhaust which helps it to work out if the car is running lean or rich.

thanks man
