bank 1 will be whichever side cylinder 1 of your engine is and bank 2 will be the opposite side. It's named bank 1 and bank 2 so that no matter how the engine is laid out, bank 1 is always on the same side as cylinder 1. I cannot say whether the right hand or the left hand one will be bank 1 as I do not know where your cylinder 1 is. The garage should know

The upper sensors are air fuel sensors and the lower ones are o2 sensors. you cant mix these up. Assuming you did everything right and still coding then either the new sensor b1s2 is bad or the wirng(power and ground need to be checked. A scan tool can be used to look at the performance of the sensors too. Sometimes the codes just point to the area of the problem and changing the part isn't the answer.

I have a 2001 kia sportage 4x4 its starts idles runs and then sometimes it stalls while driving cuts out and dies fuel pump has been replaced relays have been replaced fuses and fuel filters help!

Does your vehicle "hop" forward a bit when you are driving or coming to a stop. I had a similar complaint about my 2001 Pontiac Grand Prix and for me it was a mass air flow sensor replacement needed. The other thing it could certainly be is a clogged catylitic (sp?) converter. That will cause the symptoms your vehicle is having too. Good Luck. Hope this was helpful to you. Have a great day!

1999 Chevy Venture stalls while stopped and sometimes while driving

Well it could be several differant things .It depends on how it stalls .If it just cuts off in an instant meaning its running good one second and the next it stops running completly then its likely an electrical problem . But if it starts sputtering and looseing power then stalls its more likely a fuel related problem witch is more likely .My best guess would be a colged fuel filter or a bad fuel pump .If you arn't getting engine lights comeing on or even if you are and then they go out by it self the fuel filter is the first thing to look at and its the easyest and cheapest thing to do .The filter on your vehicle will be located under the drivers door and mounted to the inside of the frame rail .On a 99 if its never been changed its time it should be changed every 4 to 5 years . I can't say for sure but it sounds like the most likely problem and it can't hurt it costs about 10 dollars .See if it helps good luck

Kia Rio cutting off

im assuming that changed the oil unit you mean sending unit ? if so could be electric short in the pick tail or worse wiring harness. second there is also possoble vacum leak .third while unit was being replaced something didnt get put back or got knocked loose. created a new problem. most times as thing are going bad they dont register until it is a prolonged problem as it took 2 days for the check engine to go out that also might have been normal. you might also notice while sitting at park when you turn the wheel you will notice ia differance in the idle, if its almost stalling then its probley your idle,needs re set, or your idle controle valve is going bad ,did it get checked or cleaned when they serviced the throttle body. and also could be your mass air flow sensor going bad or need cleaned

4 wheel drive lock up

hey charlie, 1st problem is 4 wheel drive being engaged on dry pavement. You should only have it in 4x4 in snow, or off road on sand, dirt,etc. Newer all wheel drive vehicles compensate for the tires rotating at different speeds, like going around a sharp corner. The wheels on the outside of the turn have a longer distance to travel than the wheels on the inside of the turn. This results in the vehicle feeling like it's jumping, hopping or jerking as you cut a tight turn. You can damage your 4x4 system, as the wheels are fighting each other, trying to turn the same # of rotations, and something can and will give (like blowing the transfer case). If your light is staying on after changing to 2 wd, it is possibly stuck in 4x4. To shift from 4wheel to 2 or 2wheel to 4, you should be traveling in a straight line, let off the gas, change in or out of 4x4, resume driving. 4x4 low range requires a complete stop to engage.

Vehicle Stall - Ford Focus X Reg

I will suggest some cheap areas to try first.
1.Wiring connections to your computer under the dash.
2.Check wiring to fuel pump.
3.Check black boxes under hood. They have relays and terminals may corrode.
4.Ignition switch, sometimes with heavy keychains the contacts can loosen.

Take it to Autozone or Oreillys for a free scan. When you say car cuts out, does anything work like lights, horn, radio? Please post symptoms and if anything has helped you.

My hyundia tucson keep cuting off when i drive the jeep and i have to stop it cut off any time i stop it cut off and when my foot on the brake it move when myfoot is on brake

If the vehicle is stalling when coming to a stop or slowing, look at your throttle position sensor on the throttle body. it is small, almost a box with 2 phillips head screws(not the sensor with hex head bolts, right behind it). If it is grey in color, change it.

Corsica stalls at stop signs

sounds like the EGR valve is sticky, take a small screw driver and tap the valve when the engine is at idle and you will notice a change in the way the engine runs, if the vehicle smooths out disconnect the valve and drive the vehicle and it should not cut off please let me know and dont forget to rate me!!
