2010 Aveo5 CEL P0053

[Jiggs]

Have had this car about 6 months, 58,000km or about 34,000 miles on it. CEL came on after oil change, immediately after. Mechanic who also owns a 2007 Aveo did testing...vacuum leaks, exhaust leaks, checked wiring etc all good & confirmed upstream o2 sensor needed replacing. We tried two aftermarket sensors that crapped out after the 3rd cold start. Now trying a GM OE sensor....which is more than double the cost.

Mechanic was told by GM service that these cars can be pretty temperamental when it comes to aftermarket replacement sensors as even a very slight change in resistance will trip the CEL.

Guess we'll find out. Not too sure what we'll do next if it trips again. Anyone else have this particular issue that was solved by using an OE sensor?
