Six cylinder two wheel drive automatic 58,000 miles.

Hi,
A check engine light came on at around 57,000 miles. I took it to the Acura dealer and they want to replace a sensor. The care drives fine other than the check engine light (which is going to cost about $500.00 to fix) is this something I can do myself? Do I have any other options?

Thanks,
Nadeem

It all depends what the sensor is, did they tell you which one you need?

Here is what it says on the bill for the diagnose charge: Part 57812 code P1172, B1S1 A/F sensor out of range.

I called the BBB Autoline to find out if this kind of repair is covered under the extended warranties (8/80) and they are not cooperative at all.

Thanks,
Nedu

P1178 O2 sensor signal circuit slow switching from rich to lean (bank 1 sensor 1).
The other one I am not familiar with. If you know someone handy and semi mechanically inclined, they can change that o2 sensor, easily.

To change an oxygen sensor (o2 sensor) you just unplug it, and unscrew it from out of the exhaust pipe/manifold, and replace it. Also, if your up to it, the mechanics that do the repairs for the dealers, will do work like this on the side, for like fifty dollars, to change an oxygen sensor, all you have to do is ask them. Pull them to the side, and ask them. Because of the difficulty, there are really no instructions to do this because you just unplug and unscrew.

TL P1172 Bank 1 sensor 1 is out of range. I bought the sensor online. I need to know exact location of this sensor on the car. How do I get to it? Is it under the hood or under the car? Are there any instructions available online? Are there any photos available? I would really appreciate any help.
Thanks,

Here you go, it should be fairly easy to do because it is right in the front of the engine.

I replaced the sensor (bank 1 sensor 1) with part number BS13965 oxygen sensor but the check engine light is still on. I try to rest it by unplugging the battery, the light went away for about five minutes but then came back. I am not sure why. Is this the correct replacement part? I would appreciate your help.

Thanks,
Nedu
