I recently installed a set of LG Street headers, cam and LS6 intake manifold on my 2000 C5. As part of the install, I bought an additional set of rear O2 Sensors and installed rear sensors with adapters in the front bungs and rear sensors in the rear bungs (after high flow cats). Since putting the old rear O2 sensors in the front, I am getting codes 1133, 1153 which I believe are caused by erratic voltages or slow response from the fwd O2 sensors. I had the car tuned after the install, which made it run great, but I am still getting the codes occassionally. My tuner (Ed Hutchings) also deleted the rear sensors, when I had it tuned. I am looking for advice on what I should try to correct this. I have read a couple of threads that indicate the front type sensors respond faster and are needed in the front locations. This does not make much sense as I believe the sensors are similar, with exception that the rears have a stronger heating element. I plan on taking the new ones I put in the rear bungs and move them to the front and put plugs in the rear, unless their is truth to the front sensors being more responsive. Appreciate any advice. Thanks.

 

Same exact case as you man.....my car goes in this thursday and I already warned the tuner....Hopefully he can do something about it....if you find out something please PM me and I will do the same for you bud.

 

Had the same problem It was the fuse #15 in the panel by the battery It is a 15 amp mini fuse. Hope that helps. Usually caused by wires getting shorted or burned on the headers. Hope that helps

 

Long tubes often cause those codes. ie: insufficient switching. Have the tuner turn off the codes 1133 and 1153 in DTC processing enablers and DTC mil enablers. It will not affect how the car runs or tests for emissons.

 

Do you know if the P0133 - slow switching, is common as well?

 

P0133 - 02 sensor slow response.

It could be anything from a bad sensor, exhaust leak, electrical problem, or blown fuse. Do you have new headers?

Check the fuse for the o2 heaters in the fuse box next to the battery.

 

I had this code also. At first I thought it was the exhaust leaks but after I fixed them the car continued to idle extremely rich. I decided to order some extensions and put the orginal fronts back on. Now my idle is clean again, I have not driven it enough yet to see if the codes appear again but I don't think they will. My car is 03 Z of mid year production. Anybody else seen this ?

 

My tuner has informed me that this is no problem for him and that he will take care of it. My guess is that these codes have to be turned off and then the car properly tuned to put it back in range so that the codes do not come back.

 

This is going to sound like a really crazy theory, but here goes:

I have a 1997 C5 with 228/232 cam and immediately after heads (243) and headers (dynatech) I started throwing 1153, 1133 and 1154 codes. Also an occasional 0133 and 0153, and maybe there was one 1134 thrown in there somewhere, don't remember.

I had a loud tapping that I was trying to diagnose for the longest time, and I ended up fixing it on the drivers side with 8 slightly used (but much newer than mine) rocker arms. At that point, without me really noticing it, the 1153, 0133 and 1133 all dissappeared <-- note they are all bank 1 or driver's side. 1154 persisted and occasionally 0153 still showed up. After fixing the extremely obnoxious tapping on the drivers side, the pass side reared its ugly head. Did I mention I originally went with 243 heads to change to LS2 style lifters since I thought that was the source of my tapping? Yeah, I chased that for a while and was pretty dissappointed when it came back. Reluctantly, I ordered a set of rocker arms to get the other 8 for the pass side.

Just finished putting them on and a test drive. 1154 magically dissappeared (for the moment) and the tapping is much better.

Does it make sense? NO.
Is it a coincidence? MAYBE.
Just food for thought. Maybe try new/slightly used rockers if you suddenly throw codes after H/C and headers? I could visably see and feel no difference between my rockers and the ones I got in the mail. Felt, looked, smelled (tasted?) the same.

I'll keep you updated on whether the mysterious 1154 code comes back, but for now, feels pretty good.

 

Well my codes came back. One day it was P0153 cleared the code out and the next time the CEL came on it was the other side P0133. My mod was simply LG Pro headers. Today I bought new GM front sensor and installed went for short drive no codes will drive some more tomorrow with crossed fingers. By the way I checked the fuse no problems there.

 

While driving home from my tuner a code returned: P0133 I think....It was a switching issue again with the 02s. My tuner said Yes, he could turn off the codes that cause this but that wouldn't fix the problem only mask it. He recommended changing the 02's or maybe even buying new since mine were 72,000 on them. It is weird though.....I drove 8 miles and my check engine light came on throwing the code. I stopped reset the codes, started it up and then drove 150 miles never tripping it. hmmmmmmmm I must be right on the edge of acceptable range or something.

 

 

I have been Throw'in the P0153 ...Check engine dosn't trip(ever sence I did a H/C/I/LT's no cats etc...

You do NOT Have to stop to Reset the codes...Just press the options and hit the fuel 4 times...then when PCM shows the code...press reset...goes to manual mode...then press the reset and away goes the Code...

My service engine comes on with the 1870 all the time...Well Ever sence I changed out the rear from a 2:73 to a 3:42...

 

I've been reading quite a bit of history from the forum on this subject. Usually associated with LG headers from what I can tell. However, after I installed a set ARHs the P0153showed up. I haven't had it tuned yet, waiting for Carlisle to have ESC perform the dyno tune so perhaps that will solve the issue.

There is a member on the forum (Russ) who's suggested tuning out the code is the way forward.
