My OBD2 is not picking up my speed sensor but my speedometer is working fine does anybody have a suggestion where I can start looking?
​​​​​​ my car is very heavy on juice and everything else is perfect my short-term fuel pressure long-term fuel pressure and my oxygen sensors are working perfect all I can think is that the speed sensor has got something to do with the fuel economy. My car speedometer is working perfect but the OBD2 says that the speed sensor is faulty,but my speedo is working. It suddely went geavy on fuel, , i now get 5km per liter,before it was almost 10 km per liter
