Man my car is giving me problems left and right. I just got my car fixed 3 weeks ago because the check egine light came on and now it's going off again. I have 125k on the car, I just spend $500 three weeks ago fixing the other problem. Can anybody tell what how much it would cost to fix with the following problems

1206 - Diagnostic Trouble Code 1206 points to a problem with the TPS.

0304 - Diagnostic Trouble Code 0304 points to a problem with the Knock Sensor. The KS is attached to the cylinder block. It senses engine knocking using a piezoelectric element. A knocking vibration from the cylinder block is senses as vibrational pressure. This pressure is converted into a voltage signal and sent to the Engine Control Module (The computer).

0403 - Diagnostic Trouble Code 0403 points to a problem with the Throttle Position Sensor. The TPS responds to the accelerator pedal movement. This sensor is a kind of potentiometer which transforms the throttle position into output voltage, and emits the voltage signal to the Engine Control Module. In addition, the sensor detects the opening and closing speed of the throttle valve and feeds the voltage signal to the ECM.

Thanx
