This may not be completely relevant to original post, but DTC P0122 haunted me for months on my Canadian 2005 Chev Optra5 (sister car is Suzuki Reno / Forenza in USA), I would switch out sensors, the code would go out for a bit, then come back, I decided to get the transmission fluid changed at a reputable transmission garage, the mechanic said I also had a P1122 code. Anyway, since the tranny fluid was replaced the check engine light has stayed off, been 2 weeks. Worth doing anyway.

Update from May 25, 2019: UPDATE: P0122 DTC SOLVED: REPLACED ECM WITH RE-MANUFACTURED ECM FROM FLAGSHIP ONE: https://www.fs1inc.com

DEALER REPROGRAMMED 1.5 HOURS LABOUR FOR INSTALL/REPROGRAMMING

2005 OPTRA5 NOW RUNS LIKE A DREAM; NO MORE INTERMITTENT P0122 DTC.
