You may have heard of emo band Dashboard Confessional, but the real dashboard confessional is your check- Used Engine light — and depending on where you live, that ominous glow may stir up more emotions than a sad song. For example, in Connecticut, car owners may feel fear and loathing at the thought of an average repair bill of $411 — the highest in the nation, according to a new study by California-based CarMD.
The automotive diagnostic information provider examined the costs of parts and labor for car repairs that trigger vehicles' check- Used Engine light, analyzing more than 11.5 million fixes last year on model-year 1996 through 2016 cars. The annual state-by-state ranking also concluded that the thriftiest state for car repairs was Michigan, with an average repair bill of roughly $343, and that the most common culprit of a trip to the mechanic was a faulty oxygen sensor — as demonstrated by 35 states — which can cost from $233 to $296 to fix.
"Properly operating oxygen sensors are important to a car's performance and to the environment," CarMD said in a statement. "If left unrepaired, most check- Used Engine -light-related problems, including a faulty O2 sensor, can negatively impact a car's fuel economy and cause damage to other car parts like the more costly catalytic converter, which averages $1,190 to replace."
The 10 most expensive states (including the District of Columbia) for check- Used Engine -light repairs, followed by the average cost of parts and labor, are:
10. Tennessee, $385.90

CarMD Technical Director David Rich cautioned car owners against ignoring their check- Used Engine light because the vehicle is driving OK or they don't like the first quote they get from a repair shop.
"As we track check- Used Engine -light repair data," Rich said in a statement, "we have noticed a trend in which the states with the highest repair costs tend to have a higher frequency of expensive repairs that could have been avoided if vehicle owners were more diligent with scheduled maintenance and had repairs made shortly after the check- Used Engine light came on versus driving it in hopes it would go off."
