Question

where is this sensor and what do it make and how to fix it and where is it position in the car

Answer 1

HI there

The sensors have a 5 volt reference signal wire on them. One of the sensors may be shorted and causing the code or the ecm has failed and isn't sending out the reference voltage. Normally if one of the sensors is shorted out, you should have a code for the bad sensor.
