The simple answer is yes. Most E-check locations use a computer to check the cars diagnostics. Typically the O2 sensor will show up on your computer and oftentimes a check engine light will come on. The computer or the check engine light is an instant failure for E-check. A damaged O2 sensor also prevents your car from running at its cleanest and prevents optimal fuel efficiently. I would suggest you get it fixed. In the long run you may break even with the gas you save anyway.

If check engine light is on. Get it scanned to find the problem code. They will do this at any auto parts store for free, It may be a bad 02 sensor. Get it scanned. A vehicle can fail a state-mandated smog test because a bad, or faulty, oxygen sensor. remove the O2 sensor from the exhaust pipe ahead of the catalytic converter and look for a change in performance. Good-Day!
if the engine computer says that you have a slow O2 sensor what it means is that the sensor does not react as quickly as it should and it needs to be replaced. nox is oxides of nitrogen, a product of too lean combustion which causes cylinder temps to go too high. it sounds like replacing O2 sensor will make it happy. engine computer is having a hard time controlling lean/ rich fuel mix because sensor is slow to register changes, needs to have response time in milliseconds or engine computer can't operate properly. O2 sensors do wear out, normal service item. hope that helps
Tune it up and replace the 02 sensor that keeps setting the codes bank 2 sensor 1. Have your oil and filter changed right before you go for a retest to. That will clear up 3 codes P0300, 0155 and 0154. You might have to replace the fuel sending unit to get rid of P0463 but if the gauge works OK I'd leave it alone.
Check the oil level, to much can ruin catalytic converter. Check O2 sensors with scanner, make sure they are work accurately. Check air box while car running, apply aceteline gas with no flame, recheck scanner for O2 sensors flucuatation. Compare all sensors for flucuation of 1mv to 9mv. If sensors flucuate they are good, if no flucuation sensors need to be changed. recommend to change cat with bad sensors. Before changing cat check for bad pressure.
