Re: P0141: bank 1 sensor 2 problem...
i have this P0141 code. i know this is the O2 sensor after the cat if i am correct. my concern is will this affect gas mileage, damage the engine in any way, or do anything bad to my truck? truck drives fine btw but i am just concerned. i want to use it but i don't want to damage anything or cause some other serious stuff.
2.2 L manual
CAI [chome intake]
Other then annoying you with the service engine light, there will be no negative effects from that code. It is the heating element in the o2 sensor is going bad or is bad. The heating element warms up the sensor when you first start the vehicle so that it can get a reading to the computer sooner. I have had the same code pop up since last fall when I had to drive threw a huge water hole on a trail. I still continue to get an average of around 20mpg in town and 24-25 on the highway. Note that the mileage is a bit lower then the average 2.2 because I am running big tires.
