Check-engine light on? Before you let a shop guess, I'll come pull the codes and tell you what's actually wrong.
A check-engine light is information, not a verdict. It means the computer logged a fault code — and that code points to a system, not a specific broken part. The light alone can't tell you whether you're looking at a $40 fix or a $1,400 one. That's the whole job: reading what the car is actually telling you before anyone touches a wrench.
I come to wherever your car is — driveway, work parking lot, the side of the road — and pull the codes with a real bidirectional scan tool, not the $20 plug-in code reader they hand you at the parts store. Then I read live data, run the actual tests, and tell you what's wrong before you spend a single dollar on parts. No guessing, no upsell, no "we'll start with this and see."
The big one. I pull every stored and pending code, read freeze-frame data from when the fault tripped, and trace it to the actual cause — fuel trims, sensor readings, the works. You get the real answer, not a parts-cannon guess.
From $60ABS and traction-control faults live in their own module that a basic code reader can't even see. I scan the ABS module directly — wheel speed sensors, the pump, tone rings — and tell you why the light's on.
From $60An airbag light means part of your restraint system is offline — it might not deploy in a crash. I read SRS codes most shops can't, point to the cause (clock spring, seat sensor, a connector under the seat), and tell you what it takes to clear it.
From $60Crank-no-start, dead-no-crank, parasitic battery drain, lights and windows acting up. I test the actual circuit — power, ground, signal — instead of throwing a battery or starter at it and hoping.
From $60Misfire, stalling, rough idle, hesitation, no power. These leave a trail in live data — misfire counts per cylinder, fuel trims, O2 response. I read it and find which cylinder and which component is the problem.
From $60The hard ones — the light that comes and goes, the stall that only happens warm, the gremlin no shop could pin down. I capture freeze-frame and live data to catch what a quick code-read misses.
Quoted on-site1. Scan. I plug in the bidirectional scan tool and pull every code — engine, transmission, ABS, SRS, body modules — plus the pending codes a basic reader never shows. I read the freeze-frame data so I know exactly what the car was doing when the fault tripped.
2. Live data & active tests. Codes are a starting point, not the answer. I watch live sensor data with the engine running and, where the tool supports it, command components directly — cycle a solenoid, fire an injector, test an actuator — to confirm what's actually failing instead of guessing from the code alone.
3. Pinpoint the real cause. I trace the fault to the specific component or circuit. A code that says "lean bank 1" could be a vacuum leak, a weak fuel pump, or a dirty MAF sensor — I find out which one it is on your car, not which one is most common.
4. Flat quote before any repair. You get a clear, flat price for the fix — parts and labour — before I touch anything. No HST, no surprise line items, no "we found a few other things." If you want to think about it or shop the price, that's completely fine.
5. The diagnostic fee rolls into the repair. If you have me do the repair, the diagnostic fee comes off the bill — you're not paying twice. And if it doesn't fix the problem, you don't pay full price. That's the guarantee.
A shop diagnostic usually means a tow or a nerve-wracking drive with a light on, then leaving your car for a day and waiting on a callback. I come to you — driveway, office lot, wherever it sits — scan it on the spot, and you hear the answer from the person who actually read the data. You're there for the whole thing. No drop-off, no rental, no mystery. And you already serve real customers this way: I handle diagnostics for a used-car dealer in Oakville, including a 2023 Ram 2500 Cummins diesel — heavy-duty stuff, done in their lot.
This is the part shops won't always tell you: a fault code points to a system, not a guaranteed broken part. The classic is P0420 — "catalyst efficiency below threshold." Half the internet will tell you that's a $1,200 catalytic converter. But a P0420 is often a lazy or dead downstream O2 sensor reading the cat wrong, or even a small exhaust leak letting air skew the readings. Replace the cat on a bad O2 sensor and you just spent four figures and the light comes right back.
Same story with a misfire. A P0301 tells you cylinder 1 is misfiring — it does not tell you why. That could be the ignition coil, the spark plug, a leaking or clogged injector, a vacuum leak, or low compression from a mechanical problem. Six different causes, six very different price tags, one code. The only way to know is to test each one — swap the coil to a different cylinder and see if the misfire follows, check the plug, watch the injector, run a compression test.
This is exactly why parts-store "free code reads" cost people money. They hand you a printout that says "P0420" and you walk out thinking you need a converter — so you buy one, or a shop sells you one, and the problem isn't fixed. Throwing parts at it is the number one way people overspend on car repairs. I test, I don't guess. You pay once, for the right fix.
Don't let a shop guess on your dime. I'll come to you, pull the codes, and tell you what's really wrong — flat quote before any repair. Available across the GTA.
