Car diagnostics in Repentigny

The check engine light doesn't say what's broken. It says where to look. We test before we replace.

A fault code points to a circuit, not to a part. An oxygen sensor code can come from the sensor, the wiring or an air leak upstream. We plug in, read live data with the engine running, and confirm the cause before we quote a repair. It takes longer than reading a code, and it costs a lot less than replacing the wrong part.

Frequently asked questions

My check engine light is on. Can I keep driving?

If it's steady and the car drives normally, yes, long enough to book an appointment. If it's flashing, that's a misfire: ease off and have it checked quickly, or the catalytic converter can be damaged.

Why not just read the code?

The code points to the circuit at fault, rarely to the exact part. The same reading can come from a sensor, the wiring or a leak. We test before we replace, so you don't pay for the wrong part.

Do you clear the codes after the repair?

Yes, once the cause is fixed. Clearing a code without repairing anything only turns the light off for a while, and erases the data that helps find the fault.
