I got my pocket logger all hooked up today and decided to see why i have been running pretty rich with random back fires. Well come to find out, i am getting NO reading, yes no voltage off o2 bank 1, but i am getting readings off bank 2. bank 2 will cut out sometimes and the car will throw a fuel trim check engine light.
anyways, the car runs fine and does not act as if an o2 is unplugged but does not have any readings for o2 bank 1.i even went under the hood and unplugged the 1st o2 sensor while the car was running and nothing happened. The car ran the same and drove the same. So i am trying to determine if either A the wiring for o2 bank 1 is jacked, or 2 i have some other serious problem.
Also the ECu will not throw a code for a bad bank 1 o2 sensor or anything related to that. The only one it threw was the one i listed about the fuel trim. P0170
any help will be greatly appreciated.
