AOA.
So i checked the voltage on the O2 sensor yesterday, and its giving reading of 0.6 - 0.7 volts, which is sometimes constant as well (like it stays on 0.64).
Engine is d15b dual vtec, O2 sensor is 1 wire. I tested when engine was already warm.
I read around that it should constantly fluctuate between 0 and 0.9 with running engine.
I tested the Ohms, which is shows 0.00, which means ground is fine.
Does this mean the O2 sensor is bad? How much will a new one cost?
I took off the O2 sensor to look at it physically, and its kind of clean (brownish). No carbon spotted.
Any help will be appreciated.
Regards.
