1.8TsBLOW

about a week ago i installed a megan racing test pipe with o2 simulator. every two days i pull the P1519 aic circut malf code. i clear it and two days later the same thing. i have been doing this for a week and am very frustrated. Has anyone pulled codes when installing a test pipe, and if so, is the that same code i am pulling?? I have NEVER had a single problem with my car and the coincidence when installing the test pipe just made me wonder. I tried disconnecting the battery to let the ecu re-boot, then clearing the code, still no luck. This is very irritating and would like to get it taken care of before winter storage of my S2K.

PLEASE HELP ME?!?!
thanks guys

different them my test pipe code, however do you have a 02 sensor fix? Because if not you are going to get a cel.


You need to go to the Technical forum above and It will have a thread in there about fixing your problem.

a P1519 is totally unrelated to the test pipe.
