O2 SENSOR

2003 Honda CRV

Computer problem
2003 Honda CRV 4 cyl All Wheel Drive Automatic 45,000 miles

The check engine light came on and the OBDII code reader stated the O2 sensor has no activity, code P0134. I found out that the CRV has a front and rear O2 sensor. How do I go about finding out which sensor is the bad one? Thank you!

Hi sirjr,

Thank you for the donation.

P0134 = bank 1
Bank 1 = Front sensor ie. Before the catalytic converter.

Bank 2 = Rear sensor ie. After the catalytic converter.
