The code for the G Sensor is causing my check engine light to come on. Does anyone know what the G sensor is and where it is located? I have to pass inspection and need to fix this problem. It is for a 97 Rodeo.

 

I have the same problem Codes P1391 and P1392 G sensor (Rough Road Sensor) voltage low and G sensor (Rough Road Sensor) Voltage High.


My inspection expired in January and I am trying to get this thing to pass and no-one seems to know what the hell this sensor is or where it is located. Not even the Isuzu dealer in town could help. Any ideas?
