Bank 1 Sensor 2 The Ultimate Troubleshooting Guide for Mechanics

You'll need to determine bank 1 vs. bank 2 to find the upstream and downstream O2 sensors. You can tell which bank is which by looking at the ... If its reading 0volts you can have a wiring problem, a faulty sensor, no power to the sensor, etc. If the cat has gone south then you will ... The O2 sensors on these models should be found at the initial cats which are found immediately after the exhaust manifold. Sensor 2 is always after the catalytic converter. Sensor 1 measures exhaust before the cat, and Sensor 2 measures the exhaust after it to make sure the ... Passenger side is #1,2,3,4 from front of car to rear. Driver side is #5,6,7,8. Bank one sensor two would be passenger side, rear sensor. There are two O2 sensors, an upstream (on the rear exhaust manifold) and a downstream (on the side of the catalytic converter). The downstream ... ... sensor locations by Bank and Sensor (e.g. Bank 1 Sensor 1). Oxygen Sensor Positioning. In the diagrams below, the longitudinal engine orientation ... Re: Oxygen Sensor, Bank2 Sensor2 (o2s22). User avatar. by hrmwrm. Thu Sep 12, 2013 1:10 am. bank 2 sensor 2 is the drivers side exhaust, sensor after the cat. Bank1 Sensor2 is the O2 sensor that is found screwed into the bottom side of the pre-catalytic converter (aka, downstream). It is the one located between the ... Here's what you need to do if your engine is showing error code P0138, which is triggered when the engine control module detects a high ...
