2005 Chevrolet Trailblazer Q&A
2005 Chevrolet Trailblazer Question: I have gotten codes 410, 130 & 133. Im told these are oyxgen sensors.
dont replace anything yet. code numbers never identify bad parts, just failed systems. you need someone to diag the codes and find the exact failure. guessing is expensive and usually wrong Roy - mastertech6371
