hello all , just had a friend do a scan on my car and it came up with fault code 121 and 125. I think they are o2 sensor and map sensor, can any one shed some light on these for me please and the location cheers

O2 sensor is on the exhaust either between the manifold and Cat (visible from engine bay) or after cat (visible underneath at front of exhaust). Not sure which as unfamiliar with 2.2 codes.

Map sensor is on air intake between Maf sensor (big tube next to airfilter) and the throttle body. Iirc it's about an inch in diameter and is plugged into the big rubber pipe just before it drops down to the throttle

P0120 is TPS. P0125 is undefined.

What ECUs did they come from? Neither codes point to lamdas
