I have a code showing up causing my MIL to come on. I have MAC lontubes with MIL eliminators and o2 sensor extensions installed. Would fualty MIL eliminators be causing this??? This is the code I am getting P0153. I have cleared the code but it comes back after about a day.

P0153 Upstream Heated Oxygen Sensor circuit Slow Response - Bank No. 2.

 

I believe that is a normal code for Longtubes because they move the O2 sensors further back. A tuner should be able to clear that problem up for you.

 

Its normal because the o2 sensor isn't heating up as fast as it should do to it being moved back.

 

yea your MILs prolly arent working right. are they the steeda MILs? ive heard that sometimes those have a tendency to not work right for some reason. new MILs or a handheld tuner should fix your problem.

 

thanks for the replies...does this affect performance?

 

MILs are only for the rear O2s. He got the code for the front O2 sensor. Upstream means the first O2 sensor, on the passenger side
