Y-pipe installed and CEL!!!!!!!!!!!
I installed my (budget) y pipe and reset the ecu and the next day i recieved the CEL,(Codes 0510,0512) I installed the fact 02 sensors (46,500 miles)and a test pipe off ebay and got these codes, oh yeah also got the bees in the can ;0) But the first day of driving back and forth to work approx 30 miles everything was fine, except my axle back aftermarket muffler got allot louder. Kind of to loud for my taste so i put my fact one back on and that day is when i got the check engine light? maybe backpresure? Any one had this experience? Is it that dam test pipe? or did oxygen sensor crap out?
Thanx

A test pipe will trip your CEL with a code for the rear heated O2 sensor, even if you have no air leaks. The rear O2 sensor looks for a variation in O2 as compared to what the front O2 sensors are sensing. A difference in O2 detected by the rear sensor indicates that the cat is doing it's job. No difference is an indication that something is wrong, hence the CEL. Since you have no cat, you get the CEL.
There was a recent thread about this very thing and how you can use an ebay item to trick the ecu into thinking you have a functioning cat. I'll have to look for it.
