Trouble Code
hey guys this past Friday my check engine light came on and i plugged in my SCT to see what comes up,i got the trouble code P1151
http://www.obd-codes.com/trouble_codes/ford/p1151.php so i already cleared it,but my question is should i worry about this,my car seems to be running normal...? |
Lack of Upstream Heated Oxygen Sensor Switch - Sensor Indicates Lean - Bank No. 2
You might need a new O2 sensor |
which one, a rear o2 sensor?
|
99% sure it's driverside and if it's upstream which it is I'm pretty sure its the one before the cat
|
you must have an aftermarket mid pipe.
|
He has a O/R pipe.

Gotcha. If you have been thinking of getting an Xcal or any tuner, you can also turn them off using that. Just an added incentive to get one ;)
Thats whats strange though.....on the O/R pipe you need MIL eliminators or you need to shut them off with a tuner. The O2 sensor thats throwing the code is the one that NEEDS to be there the fronts. |

Hmmm... Well I have catted SLP Xpipe and I threw both bank 1 and 2 codes because of flow. It basically was throwing this because the 2 pre-limenary cats were eliminated due to the SLP Xpipe. We by-passed this w/ the tuner. I don't have MIL eliminators, since I have catted pipe, correct? My 02 sensor's were just picking up the extra carbon or whatever it is to throw the a/f off.
There is a upstream and downstream trouble code and the one he is throwing is the one in the front. The codes you threw are probably both the downstream which is past the cats he is throwing the one beofore the cat or the one in the front. |

I have a catted pipe too but had mine shut off in the rear just for the fact I wont have to pay for them when they crap out:Woot: . But thats not the point.

BUT, I don't know what to tell him since he doesn't have one. I don't know what to do then. |

You would still be able to turn that off with a tuner however.

The reason why you should change it before it fails is when the oxygen sensor fails, the computer can no longer sense the air/fuel ratio, so it ends up guessing. Your car performs poorly and uses more fuel than it needs to. |
