1 Answer

74,645

I looked up the codes, 33 is for the map sensor but you have that replaced. 44 & 45 are the oxygen sensors, probably should replace the 02 sensors. If there is still troubles, the TPS (Throttle Positioning Sensor) is related to the map sensor, but should be showing a code 21 & 22.
