Error code P0155 Y26SE
« on: 02 December 2017, 21:37:38 »

Hi!

I recently bought an 2001 Omega 2.6 with a manual box very cheaply with some problems.
It has some minor rust issues and some instrument cluster bulbs that are dead, but mainly it's the P0155 error code.
This is the only error code there is right now, and when cleared I can drive around 10km before the code reappears.

I bought a new O2 sensor cheaply and hope this fixes the issue with the error code.

So, to get to the point. P0155 seems to be pointing to "bank 2, sensor 1", is this always on the left side of the car (my drivers side, passenger side in the UK) in front of the catalytic converter? I just want to make sure I change the correct sensor.

To clarify "in front of cat", on a standard 2.6, both sensors for that bank are "in front of the (main) cat".


Manifold - Sensor 1 - Starting Cat (also called Pre Cat) - sensor 2 - main cat


So you are looking for the forwardmost of the 2 sensors on that side, on the downpipe section
