Hey everyone. So a few months ago I installed berk high flow test pipes along side my FI cat back exhaust and got a remote tune shortly after from a fairly reputable tuner. Every so often i have gotten the following codes…
p0139(02 sensor slow response(b1,s2))
p0159(02 sensor slow response(b2,s2))
And just today I got them but with more codes…
p0138(o2 sensor high voltage(bank1,sensor2))
p0158(o2 sensor high voltage(bank2,sensor2))
Supposedly berk test pipes come with built in o2 sensor spacers to prevent these codes from happening but obviously not doing the job. They could be dirty and I haven’t cleaned them but I heard I could just ask my tuner to tune them out completely. Why this wasn’t done on the initial tune I do not know but any input on this would be helpful.
