So I installed the XS power headers over the weekend. First day didn't throw any codes but today I got a bundle. Are these codes normal with a header install? I am getting it tuned this upcoming weekend. Will driving it hurt it at all? I got the catted version.

Thanks!!

looks like you may of crossed them the wrong way.

 

Looks like you have them all....

No, not normal. Inspect the wiring for heat damage, and check minifuse # 15 in the underhood fuse box.

 

Hopefully you get it figured out quick, but I have to say that may be a record

 

Just checked the #15 fuse and it is blown. What does that tell me? besides the fact I need a new one.

I have all 4 02 senors hooked up. I know I didn't cross any. I made sure to mark them before I took them off. Besides you can't really mess up the front ones cause they are on each side. The rear ones both go in at angles so another easy one.

Just got home so I will check the wiring once the car cools down.

Thanks again for all your help.

 

You may want to just double check something didn't short, i.e., wire on exhaust.

 

Impressive list.The sensor 2 codes are the rears and will be tuned out. I also agree you may have a shorted/melted wire

 

I'm guessing you had the battery still hooked up?

 

Okay the mini 15 fuse was toast. I replaced it and it still blew. Now, the connector for the driverside rear 02 is a little burnt. So I am guessing that is what is causing the codes to be thrown and the fuse to blow.

I have a predator tuner that can tune out the rear 02 codes. (Until I get my dyno tune in a couple of weeks) Can I just disconnect the rear 02 wires and cut them at the sensor so there won't be a short anymore? This way the fuse (which runs both front and back) won't blow. So all I would have would be the rear 02 sensors sticking out of the pipe with no wires attached.

Oh, and the sputtering and bad idle was b/c of a cracked spark splug (go figure)

Thanks guys!!

 

Anyone??

 

Why guess? Use a meter....and isolate the short.

Certainly not my style, but to answer the question, yes you can. If you don't isolate the short, you risk the short being on the harness side.....and you hack up the O2's for nothing.

 

Providing the short is past the connector, yes you can simply disconnect and tune out the rear O2's. However that won't clear up all your codes, just the Sensor 2 codes and any caused by the short.

 

Check your wiring and make sure it is all free of the exhaust. You may have cooked one of the wires. I did this once and it did the exact same thing... cooked the #15 fuse and it would keep on blowing when I replaced it. I found where one of my O2s burnt, replaced it and made sure it was tied up good and haven't had an issue since!

 

All the "sensor 2 " codes are part of the cat protection system---Those should all be tuned out and the enablers set to "not reported" AND the COT system should be turned off---
The "sensor 1" codes are a different story---- The inherent issue with LT headers is that the 02 bungs on the LT's are further back then they were with the stock manifolds-----These new locations give erroneous 02 voltage data back to the ECM----making your car run closer to 14.2 in closed loop rather than the original Stoich of 14.68 much richer-------Also the furher aft location will tend to NOT let the 02's heat up properly---make sure they are quickly oscilating between
.100 and .950 ----slow response codes are normal---AND sometimes if you run a lazy 02 too long it will permaantly foul it and it will be junk---
many people will install the REAR 02's into the front locations with LT's---As the rear stock 02's are much more sensitive and respond better to low heat--
You have opened up a whole new can of worms with LT's----Thts why the are illegal in most states----because they create many isues that cannot be corrected without a full blown tuner---

 

So,,,,, ,,,, you incorrectly install the O2 sensor connectors and wireing and burn it up.

Your going to need to REPAIR the wiring /connector issue. The O2 sensor heater circuit supply voltage is COMMON to all the sensors and if the bad wire/connector isnt fixed, it will effect the primary O2 sensors and engine performance.
