View Full Version : 2003 CRV gives diagnostic code PO134. I know it is an O2 sensor but which one?

Engine light comes on on my 2003 Honda CRV. 100,000 miles approx. My cheap scanner gives code of PO0134 but all the auto parts guys can tell me is that that code is for an O2 sensor but the car has 2 different ones. They can't tell which one that code is for. If there is no way of telling, which one goes out more often?
Thanks in advance.

p0134 is for the front A/F sensor (expensive oxygen sensor) being fixed high or low. Best to use honda replacement I have had many problems with aftermarket sensors.
