2007 Cadillac DTS (VIN Y) "Why" would a mid ship cat monitor O2 sensor (HO2S Bank 2 Sensor 3) heater circuit have anything to do with the Climate Control Seat module?
Must have bottomed good on a speed bump or more likely when it was in dealer for service contract warranty work for fixing crankcase oil leaks the tech when reattaching the exhaust system wasn't paying attention I'm not going to attempt to bend the exhaust system back down . Just replaced the damaged HO2S and cut a u shaped section out of the damaged center end of the heat shield.
Even after checking all fuses under hood and under seat were ok and doing a O2 Heater relearn reset, I was unable to clear the P0064 code from the Climate Controlled Seat module which worked fine on both front seats for heat and cooling. P0064 did not ever show as a code in the PCM that I was aware of.
Maybe I missed it, but I did not see the HO2S Bank 2 Sensor 3 in the VIN Y Engine Control wiring diagrams nor did I see a wiring diagram or trouble shooting codes for the Climate controlled front seats.
