I,ve been driving with the light on for weeks.
I believe it is the oxygen sensor.
Error high voltage Bank 1 sensor 2.
Is this sensor the one after the catalic converter.
How can i check it if its bad?
How can i check the wiring if it bad?
can it be the fuel presure too high?
Symtoms are some hesitation and some odor of gas or exhaut.
I bought a code reader.
Can i get more info from it to help me pin down the problem.
Thank-you for the support.......Gino
check engine p0138 code on 2004 Saturn Vue
I would recommend replacing this sensor with a factory part or OEM equivalent. Once the heater element causes this code, there is little to be done with the sensor. If the car was running too rich, you would have a 'fuel trim too rich code' like a P0172 and P0175.
You just have code P0138, yes?
