Sorry you were disappointed Dave. I did review your bill and the sensor is more expensive than what you would purchase at Autozone. Unfortunately we generally don't use cheaper parts as we guarantee parts and labor for 2 years/ 24,000 miles which would be impossible to do with cheap knock offs due to a higher failure rate. We only use OE or OE equivalent. Replacing the sensor is pretty simple, we only charged $32.00 for that, the additional labor of $90.00 is a to diagnose the problem, which many times takes longer than the fix. We always make sure the correct part is replaced rather than just reading the code assuming what the problem may be.
