That's what happens when you stay frosty and work the problem...

i have an off road h-pipe w/mil's installed for 4 years now. after a year the ses light came on. code P0156 (oxy sensor circuit bank2 sensor2) i replaced the sensor with a bosch from autozone and cleared the code. next was code p0136 (oxy sensor circuit bank1 sensor2) i replaced the that with an autozone part and cleared the code again. cleared the code and off i went. i have seen both of these codes again from time to time including a code p0141 (oxy sensor heater circuit bank1 sensor2) i started taking the downstream sensors out, washing them down with brakeclean, reinstalling them and clearing the codes. i do this about once a summer...... just my experience.
