Can bad gas make the check engine light go on the oxygen sensor code p0040 came on and i cleared the codes hasn't come on yet?
I would not think so but I have learned that nothing is impossible. P0040 is not an O2 sensor code, it is a EVAP system leak. A loose gas cap will set this code for sure as the code indicates a leak in the EVAP system. If it does not come back on then forget it. If it does replace the gas car first and clear the codes. If it comes back on then check the EVAP system hoses for cuts or leaks, check the purge valve. If none of these are leaking you need to see a pro and have a smoke test run. These can be very tricky to find at times.
a fouled out oxygen sensor can result in bad fuel economy, and make that dreaded check engine light come on, it can also make your car "bogg out" / sputter, when accelerating, when replacing, make sure to get the o2 sensor socket, makes for easy replacement... as far as the check engine light you may need to stop by dealership to have it reset, most will reset for free
If you replaced the failing oxygen sensor, you have to wait 3 drive cycles or 40 warmup cycles for it to automatically clear or you have to have the Check engine light code cleared if it's 96 and up. If not, disconnect the battery for 10 min. or more. Connect the battery and it should be off. If it is not then have it read again you may have changed the wrong one.
Upstream Oxygen Sensor heater performance. That will be the first oxygen sensor in the exhaust pipe ( closest to the engine ) on the passenger side head. You need to check the wireing connector that hooks to the oxygen sensor for a broken wire are bad connection. If you find no problems, then replace oxygen sensor.
Where is the oxygen sensor located on 1996 olds 88 The car sputters does not want to move that would be the Oxygen sensor?
The oxygen sensor is located at the exhaust manifold ,behind engine, close to firewall. The oxygen sensor has no effect on vehicle until it has reached operating temperature or closed loop status in computer. If unplugged or defective computer will substitute a fixed voltage value and car will still run.It will set a check engine light
If the o2 sensor is not working, the computer will put out a code which will turn on your Check Engine light. The car/truck will not pass inspection without it being fixed. Anytime the check engine light is on, the mechanic will plug into the vehicle's computer and it will tell him the fault codes and what they mean so that he can fix them. So, if the check/service engine light is off, the oxygen…
