Installed TTI long tube headers. Prior to in the install I had no issues with codes. After 150miles +/-, the (MIL) Malfunction Indicator Lamp turned on. The errors were for slow 02 response on right & left side bank 1 sensors. (P0133 and I forgot the other #)

Attempts at correcting:
1.) Checked for leaks with hand
2.) Replaced both front 02 sensors
3.) Disconnected the battery for extended period (X2)
4.) Checked for leaks, using a smoke leak detecting system

I believe it's due to the location of the O2 sensors being further down, than on the manifolds. Question is how do I go about adjusting that or physically moving the sensor into the correct position.


TTI, has no solution and claim they haven't had that issue before. TTI charges premium prices for their products, I expected premium customer support. In my case that have been of no help. I have searched numerous topics and have yet to find one that will provide a solution. I have an upcoming inspection, and with the lamp turned on I will not pass.


Any solutions?

 

IDK man, I know all trucks are different but my O2s are way back because I have LTs and my current bungs for on O2s (no cats) are about around the middle to the back end of my trans pan.

 

How did you move the O2 sensors? Could there be a leak at the O2 bungs. I assume you had to splice the O2 sensor wires if the location was moved. Check the voltage on pin 3 and 4 O2 connector with ignition on / not running.

 

Which brand did you buy?
