Auto Scanner: Code keeps coming back on Trailblazer

Q: Here is another 2004 Trailblazer issue. I’ve been getting P0141 codes. My local guy has replaced both O2 sensors twice, and the code keeps coming back within a couple of days. The engine runs fine and I see no ill effects, yet. Where should I go from here?

A: As I have often stated, just changing parts by virtue of a code is guesswork. A half-hour or so looking at the numbers on a scanner will help pinpoint the problem. In this case, a code P0141 refers to the sensor known as bank 1, sensor 2. This sensor is actually a catalytic converter oxygen sensor monitor, and not an oxygen sensor of the raw exhaust. When using a scanner to look at the problem, you should be looking at the wave form and the frequency of zero crossovers to get to the root of the problem.

Q: I have a 2006 Chrysler Town & Country minivan. I like the car very much, except I cannot understand why the front wheels get so stained and hard to clean. The back wheels stay clean; it must be the front brakes that cause it. It has only 22,000 miles, but this has been going on since I bought it new.

A: The problem stems from the brake pads. The dust as the brake pads start to wear is going all over the wheels and taking away from the beauty of your Town & Country. I have been given many brands of brake pads to try on my own SUV, and I am experiencing the same problem you describe on the latest set, which is a highly regarded brand name. When performing brake service on your car, look for a proven brand. You may pay 10 to 20 percent more, but you will get 35,000 miles more of clean and safe braking performance.
