What is your question?
Hi. I have an 2002 Honda Civic. It had an high voltage error on oxygen sensor bank1 sensor1. And when I drive at full power after a while I always got an engine light. So I replaced the oxygen sensor with a new Denso one bought from Aliexpress. DENSO 234-4621. Now even when I drive normal rpm and slow after a while car stall just a little loose power, engine light comes up, but immediately after engine light comes up the car runs just fine and dont stall ever again until I reset the fault. Fuel long trim says 4,7%. Oxygen sensor graphs are ok. But sometimes a read 1 volt which is a bit high. But sensor reaction is fast. Bank1sensor2 is steady so I guess it works fine.
What makes this problem better or worse?
New oxygen sensor made the problem worse
How long has your 2002 Honda Civic had this problem?
For almost 2 yearsi and new problem after oxygen sensor change.
