Topic starter

Hi, my obd2 scan tool isnt reading my temperature and rpm  but it can read the battery voltage, can anyone tell me why that is, I have checked all the fuses already and there is no codes showing on my 2000 infiniti g20t, thank you


Clarification: But the temp and rpm readings are working fine on your gauge cluster?  Also, what is it displaying on your scan tool?

First try another stand till you could have a faulty scan tool a circuit your scan tool could be bad if not and your car runs okay then either one of the pins on your OBD connector on the car is corroded or bent or you have a problem in your main computer driver circuits for those systems
