CEL code read shows P151(front O2 sensor bank 2) and P154 (O2 circuit no activity). AM I correct in saying this is the sensor on the passenger side? It seem like a tight fit to get a wrench in between the firewall and the engine. Can this be done without removing the manifold? The shop says that is required and will charge at least $500 for this job. Alldatadiy does not indicate the removal of the exhaust. It also shows a specific socket for this job.

Anyone else completed this job on a 2010 XC60 3.2? Tips?
