P1133 - Heated Oxygen Sensor (HO2S) insufficient switching bank 1 sensor 1 (Rear Bank)
P0133 - Oxygen Sensor Circuit Slow Response (Bank 1 Sensor 1)
p0141 - Oxygen Sensor Heater Circuit Malfunction (Bank 1 Sensor 2) (this one doesnt make sense because i dont have a rear o2)
these have just appeared since the header install, and the P1133 is the most consistant, ut the other pop up sometimes too. i just keep clearing them with my aeroforce gauges, but i do want to get to fixing them.
o2 sensor was working fine before, no codes at all. my dad made a wiring extension using male and female delphi connectors with about 16" of wire between them. all of this was done with delphi parts and my dad has worked for them as an engineer for 26 years. no splicing was done.
im thinking ill start by checking the extension to make sure its plugged in completely (which i know it is..) and then try replacing the sensor with a used one from MPC since thats cheap and i like cheap. if that fixes the problem then good, but if not, ill end up buying a new AC Delco sensor. if that doesnt fix the problem, what else should i look for?
