Cleaning o2 (wideband in this case) sensors?
I've been troubleshooting problems with my aunt's 2000 Volvo S70 (2.4L turbo). I just replaced the MAF sensor last week. The latest code is a P0133 which is slow O2 sensor feedback. So, I look up what the price is of a new O2 sensor. I guess Volvo went and used a Bosch wideband o2 sensor on this car. So, the replacement is almost $200 from the parts store. I'd like to avoid this.
My question is, is there any way to clean the sensor?
