Hello,
If anyone has been following my other thread (http://gmtnation.com/forums/threads/2004-tb-i6-4wd-manifold-red-hot.14795/) you know I am about to replace my manifold and catalytic converter.
What I would like to do is test the o2 sensors and wiring. I also would like to check the new catalytic converter. I was reading here: http://www.autodiagnosticsandpublishing.com/feature/o2-sensor-testing.html
That site says: Stating around model year 1999, a new type of converter came on the market, called “Low Oxygen Storage Converter” or LOC. With an LOC, the pre and post O2 sensors cycle at the same rate. These converters are tested by measuring the lag-time between the two signals. A further development of this system is that the post converter signal is also used for A/F correction, but to a less extent.
One of the questions I have is what type of converter do I have on my 2004 TB. Am I going to be inspecting the phase or? What are the graphs supposed to look like?
I have more questions but I need to do more research first.
