| Catalytic converter | Converter failing, often from extended misfires | 🔴 High — expensive if ignored longer |
| Mass airflow sensor | Dirty or failed MAF sensor | 🟡 Medium — rough idle, poor gas mileage |
| Spark plugs/coils | Misfiring cylinder | 🔴 High — especially if light is flashing |
| Thermostat | Engine not reaching operating temperature | 🟡 Medium — causes poor fuel economy in winter |

Some shops around southern Maine charge $50–$125 just to plug in their scanner. We think that's backwards. If you're already stressed about your car, the last thing you need is to pay for a diagnosis before you even know if you can afford the fix.
At Up Front Auto Repair, we read your code, explain it in plain English, and then give you an honest quote with no pressure. Simple as that.
"They told me exactly what was wrong without making me feel stupid about it. Fixed it same day. Charged me less than I expected." — Recent Standish customer
Sometimes the check engine light is triggered by a sensor that's failed — not the actual system it monitors. A bad O2 sensor doesn't always mean your exhaust system is shot. A failing coolant temp sensor doesn't mean your engine is overheating.
This is why guessing (or letting a parts store "clear the code" without fixing anything) costs you money in the long run. We pinpoint the real cause.
We're easy to reach off Route 25 (Ossipee Trail West) — 5 minutes from downtown Standish, 15 minutes from Gorham, 20 from South Portland. Most check engine light diagnoses are done the same day.

Can I pass Maine inspection with the check engine light on?
No. In Maine, a vehicle will automatically fail inspection if the check engine light is illuminated. Get it fixed before your sticker expires.
Will the light go off on its own?
Sometimes — if it was a temporary fault like a loose gas cap. But in most cases, the underlying issue remains even if the light turns off temporarily. The code stays in the system.
How much does it cost to fix a check engine light?
It completely depends on the cause. A gas cap is a few dollars. An O2 sensor runs $150–$350 parts and labor. Spark plugs on most cars are $100–$200. We give you the exact number before we touch anything.
Do you work on all makes and models?
Yes — we service domestic and import vehicles. Ford, Chevy, GM, Dodge, Toyota, Honda, Subaru, Volkswagen, BMW, Jeep, Nissan, Hyundai — if it has a check engine light, we can read it.
