Check Engine Light Diagnostics in Nutley, NJ
Check engine light diagnostics at Joey's Auto Service in Nutley costs $80-150. We connect to your car's computer, read the codes, and diagnose the actual problem. Sometimes it's a $15 gas cap. Sometimes it's more serious. We tell you what it is before recommending any repairs.
What is check engine light?
Your check engine light means your car's computer detected something wrong with the engine or emissions system. It could be minor (loose gas cap) or serious (catalytic converter failure). The light doesn't tell you what's wrong. Diagnostics do. We read the trouble codes and test the systems to find the real cause.
How much does check engine light cost in Nutley, NJ?

Is it safe to drive with the check engine light on?
A steady check engine light usually means you can drive to the shop. A flashing check engine light means stop driving. A flashing light indicates a misfire that can damage your catalytic converter. Pull over and call us.
Can I just ignore the check engine light?
You can, but it's risky. The light could be something cheap to fix now that becomes expensive later. Also, your car will fail NJ emissions inspection with the light on. Better to know what it is.
Why does my check engine light come on and off?
Intermittent codes. The problem happens under certain conditions (temperature, load, speed) and not others. The code is still stored even when the light is off. We can read it.
From Joey
Half the check engine lights I see are cheap fixes. Loose gas cap, bad O2 sensor, small evap leak. People drive around with the light on for months thinking it's going to be a $2,000 repair, and it turns out to be $150. Don't guess. Come in, we'll read the code for you, and you'll know exactly what you're dealing with. No surprises.
