Checked my O2 sensors last night on the 2001
Hi all,
In an effort to resolve my SES PO420 problem, I checked my O2 sensors. As far as I know, they're OK. The precat sensor cycled from .1 to .9V...which is normal. Then there were 2 more that held steady at .285V...which seems lean.
My question is -is that low enough to set the catalyst bank 1 code? I thought that it should be around 4.5V. Also are there 4 sensors or 3 on our Maximas? The 4th connector at the front of the car had 4 wires....and without actually tracing things, I didn't measure it.
Any thoughts?
