Question about 2003 Kia Rio
Code says computer cannot read coolant temp i have replaced the sending unit i started the car let it warm up and it still does not move when i checked the code for this problem it said cannot read coolant temp and bank 1 running lean anything from you will be helpful
There are 2 sensors 1 is temp sensor for dash gauge and 1 is engine coolant sensor for computer. Does the upper radiator hose get hot and pressurized. The engine coolant sensor has two wires one has a reference voltage 5 volts and the other is signal return to computer with key on is will have a minimal voltage .25 volts this tells you that the wire is not broken between sensor and computer. the sensor is a negative coefficient sensor average sensor range about 390 ohms warms and 2400 ohms cold engine.

SOURCE: 04 kia sorento runs poorly
Might be going super simple here but from what you have said have you checked the wiring on your sensors? If you know that one works and you swap it and its not working its very possible the wires farther up are shorted or burned somewhere.

I have tried everything, but I am coming to the conclusion that I have a bad pcv letting in too much air. The concensus of how to fix it seems to be to clean the MAF with some electical cleaner or brake cleaner. Basically, you are getting too much air into the throttle body after the MAF or a dirty MAF.

OK check the CMP sensor connector for cleanliness, sometimes oil can get in and disrupt the signal transmission to the ECU. Check the wire loom continuity all the way back from the CMP to the ECU. If the error code persists remove the cam sensor, clean its tip of any debris and refit.
