Okay this is gonna be kinda long but i need some help. A few weeks ago I put some shorty headers on my truck. I painted them with what was supposed to be high temp paint made for headers. Well, when i started it up all the paint burned off. In the same week I got an xcalibrator and installed it. I now have a check engine light on. Codes P1132 and P1152. I did some searching on here and it seems the paint burning off could have ruined my 02 sensors. Oh yeah I have 90,000mi. on the truck. Do you guys think the 02 sensors are bad or is the chip causing problems? The truck runs great. From what i read these codes mean i am running rich but i blow no smoke or anything. One more thing, i have a slight leak at the egr fitting where it connects to the header. That thing just didnt line up right and i cant get it tight enough. Again it is a tiny leak, but could that be causing my problem? PLease help. I dont want to cause any damage to me engine and I dont have a second vehicle.

 

Superchips had a quirk in their programming that causes the truck to stay in open-loop, (if you have a scanner, verify if it's doing this or does it go into closed-loop) If it's staying in open-loop, contact your tuner as Superchips has a "patch" fix for this problem.

 

I dont have a scanner but, i also have no idea what that loop stuff means. I jsut emailed the guy who programmed my chip and he has the same truck that i do and the same chip so i would imagine he knows about that patch. You dont think the burnt paint caused a 02 sensor failure or the little leak is causing a prob?

 

Did you paint the inside of the header tubes? I know what you mean about the egr tube, It's a bitch to get to, somehow, I'd try to find a way to tighten it, but I doubt a very small leak there is going to throw rich codes.

By the way, when the last time you replaced the o2 sensers? The front ones should be replaced about every 50k miles.

 

I did paint the inside of the headers thats why i suspect they caused the problem. 02 sensors are stock. and i asked my buddy about closed-loop and open-loop. when i start the neigne in the morning the idle bounces around a little, could that also be the 02 sensors?

 

Well, your o2 sensors are overdue for a change but the P1132, P1152 codes are exactly what is happening with the Superchips programming quirk. First step would be to verify that your tuner included the "patch fix" in your tune, if not, that will answer your "check engine light" problem.

 

Thanks for the help. I am waiting to here form my programmer but I guess i need to replace the 02 sensors anyway. They are just so expensive. I hate sepnding that much money for sensor. I cant find them cheaper than $50/ea. Thanks again for the help though.

 

That's about the goin price on them puppies.
Just for your info, when you first start your truck, in runs in "open-loop" which means that it is being controlled by preset fixed parameters in your computer. As your engine warms up and the o2 sensors get up to temp, it changes to "closed-loop" whereas the computer is constantly adjusting according to the info it is receiving from various sensors.

P.S. - Stick with either "Bosch" or original "Ford" o2 sensors.

 

If you get 1132 & 1152 codes after having us do a custom tune, we can take care of that for you right away with a simple email file - that is, if you have the email update kit and we did your custom tuning.

It's a simple thing, what happens is the O2's get turned off in only a tiny fraction of a percent of F-150 strategies - they stop switching, so you get 1132 & 1152 error codes. This is quickly & permanently cured by running a fix application we tested with SCT last year - we have confirmed that it instantly works on each & every vehicle affected.

You need to immediately replace those tired old O2 sensors - O2 sensors are a 30K mile maintenance part, not a lifetime fixture. Forget carping about $50 for a Bosch O2 sensor, that's a good price, and you have to do maintenance to that vehicle far above & beyond simple oil changes - for example, by now most likely your DPFE sensor is also dying, your entire EGR tract in need of thorough cleaning, thermostat, coolant flush, transmission & differential fluids changed, the MAF meter's hot wire cleaned, fresh spark plugs (contrary to automaker 100K mile marketing spiel), a fresh fuel filter every 15K miles, etc. And yes, even a "slight" EGR leak certainly *can* cause a rich code - just FYI.
