Engine Performance problem
2002 Honda CRV 4 cyl All Wheel Drive Automatic 75600 miles
I took my CR-V to auto zone when the engine light lit up to see what the problem was. The codes that he retrieved said that there was a problem with the O2 sensor in the car. I can not seem to locate the sensor or sensors if there are more than one. The Haynes manual I have is a little vague on the location so here I am. Thanks in advance.
