What does this code mean?

P1176 Maximum Positive FMFR Correction Fault

???

It is driving fine but will it continue too?

Thanks for your help

Badger1 · 07-05-2006, 01:06 PM

Check all your vaccum hoses for cracks and leaks. If good, check for an intake leak somewhere. If none have a go at cleaning your mass air flow sensor, especially if you have been doing any offroading around mud or water. Also, when was the last time you changed the fuel filter? Just curious.

I would hold off on cleaning the MAF till you have dione everything else. If the MAF were acting up, you would also experience 3rd. anf 4th. gear tranny problems, bad gas mileage and maybe some stinky exhaust.

The code is one thing but the description is another thing. WHo gave you that description?

Check on Google: "OBD P1176" http://www.google.com/search?hl=en&l...76&btnG=Search

SO what does that mean? One of your oxygen sensors is getting old. It needs to go to the retirement home in the circular file. You reset the ECU it will come back. Oxygen sensors can be bought for cheap. DOn't let anyone fool you.

BTW, Bank 1 is the drivers side of the car.

How is that?

So if it is the O2 sensor, you should try and replace them all so you get some of your long lost power back.

I found it here

http://www.robisonservice.com/servic...er_trouble.asp

I went to a station that did inspections and they gave me the code but could not find the code in his book. I then went on line and now to you guys.

I read a few posts regarding this code here on this forum. One said to change the air filter and all the rest confused me. I just want to know what it all means (will I break down?) I have to go on a wine tour in upstate NY in a couple of weeks and do not want to get stranded

I think I am running a bit rich on the fuel does that help? It might need a new air filter too which I did order.

Thanks again for any help

Adam in NYC USA · 07-06-2006, 08:31 AM

I had the same problem so I can relate. The oxygen sensor measures changes in oxygen in the exhaust. The sensor is going to get more crankier so it will turn on the engine light more and more frequently. First every 100 miles then 75 miles then 25 miles as the part slowly goes around the drain.

If you have a friend with a codereader, you can ask them to clear a code for you. If you have a local autostore, some wil clear the code for free but eventually you will have that light turn on again.

Gas milage will go down a little and everytime the light turns on, you will go into a mode known as open loop and the car will drink gas like more than usual.

Okay?

Madeara · 07-06-2006, 10:17 AM

ok so this code is definately a oxygen sensor warning? Not a air filter that needs to be changed? I just don't know what Maximum Positive FMFR Correction Fault means.

What does FMFR stand for?

Thanks again for any help

According to Robison (again), "The code you refer to usually signals a faulty air mass meter".

I would suggest reseting the ECU and see if the code reappears. It is a rare code to appear, it seems, from the above posting.

I just thought of this (shot in the dark) BUT I have been adding a gas treatment to my gas. Could that have made it run rich? and set the light?

Sorry if I just don't "get it" its all Greek to me.

Adam in NYC USA · 07-06-2006, 11:29 AM

The gas treatment found in most auto stores wont by themselves do much.

If you have a sick sensor, it will throw a code. Old sensors throw codes when they are worn out.

Madeara · 07-06-2006, 12:14 PM

Okie dokie, I will seek out a new sensor through Atlantic British.

Thanks again for your help and patience!

Madeara · 07-06-2006, 12:26 PM

Hummph. I jsut called to price the 02 sensor and was quoted 109.95 each and there are 4! this is at British Atlantic. I think I will have someone turn off the light and I will forget about it

wade · 07-06-2006, 04:58 PM

If you recently changed your air filter, you might try putting one like the old one in. That got rid of my P1176 code.

Try calling Nathan at Discount British parts. Don't remember the phone # but if you search for it on the web you'll find it.
