This CRV is coming up with p0134, p0141 and p1166 codes. I have checked the. Resistance of the rear o2 sensor it ohms out at 3.4. I checked. Voltage to the o2 and go about 9 volts.
I checked the front and got about 14 volts. It seems to me that the issue is neither of the heaters on the 02 sensors are working Nd I'm not sure how to check my theory or how to fix it. Can someone please help.
