Turn Your Phone into a Professional Car Scanner
Plug into any OBDII port, pair wirelessly, and read engine fault codes in seconds. No more guesswork or costly dealer visits.
Three Reasons You’ll Love This Scanner
It’s not just an adapter—it’s your permanent diagnostic wingman.
Universal Compatibility
Supports all 9 OBDII protocols—CAN, ISO, KWP, VPW, and PWM. Works with virtually any petrol or diesel vehicle made after 1996 (US) or 2001 (EU).
Real‑Time Data Streaming
Pair with apps like Torque or OBD Fusion to view live sensor data—RPM, coolant temp, O2 readings, and more. Diagnose intermittent problems with a rolling snapshot.
Transparent Build Quality
The clear blue housing lets you see the high‑grade PCB and gold‑plated connectors. Compact and sturdy—lives in your glovebox without taking space.
What DIY Mechanics Say
From weekend warriors to daily drivers, real feedback after plugging in.
Paid for itself the first time I read a P0420 code. Turned out to be just a loose gas cap—saved me $150.
Pairing was instant with Torque Pro. Reads live data smoothly, no lag. The mini size is perfect—forgets it’s there.
Bought for my 2010 Corolla. Cleared an ABS code the dealer wanted $200 to diagnose. Works flawlessly.
I’m no mechanic, but this made checking the check‑engine light easy. The app explained the code plain as day. Highly recommend.
Works great on my diesel truck, but had to download a specific app for enhanced codes. Still way cheaper than a scanner tool.
Clear housing is a nice touch—you can see the quality. I’ve used it on a Honda, Subaru, and Ford, all no issues.
App could be more intuitive, but the adapter itself is solid. Reads codes as fast as my friend’s $200 scanner. Bargain.
Small enough to keep in the glovebox. Already helped a coworker diagnose a misfire. Best $20 I’ve spent on my car.
Impressed that it works with my hybrid. Read battery health and engine codes without a hitch. Definitely recommend.
3 Minutes to Your First Diagnostic
Simple steps, no mechanic skills needed.
Locate the OBD2 port
It’s usually under the dashboard, near the steering column. Sometimes covered by a small plastic panel—pop it open.
Plug in the adapter
Insert the ELM327 firmly into the port. The blue housing will face out; you’ll feel a click when seated.
Pair your phone
Turn on Bluetooth. Go to settings → Bluetooth and look for ‘OBDII’ or ‘ELM327’. Pair with code 1234 or 0000.
Launch the app
Open Torque, OBD Fusion, or any OBD2 app. It will auto‑connect. Tap ‘Read Codes’ and your fault codes appear instantly.
The Numbers That Matter
Quick specs that prove this isn’t a toy.

From Mystery Dashboard Lights to Total Clarity
That check engine light doesn’t have to mean panic—or a trip to the mechanic. Here’s how a pocket-sized tool changes the game.
The Expensive Unknown
You’re driving and a warning light flashes on. Is it serious? A loose gas cap or a failing catalytic converter? The dealer charges $100+ just to run a diagnostic, and you’re left feeling helpless and overcharged.
The 5-Second Fix
Plug the mini ELM327 into the OBD2 port under your dash—it’s standard on most cars since 1996. Fire up a free app on your phone, pair via Bluetooth, and within seconds the exact fault code appears, complete with a plain-English description.
Empowered and in Control
Clear the code yourself if it’s minor, or walk into a shop already knowing what’s wrong. You’ll monitor real-time sensor data, track fuel efficiency, and never pay for a simple scan again. Your car’s health is now in your hands.
Smaller Than a Key Fob
Keep it anywhere.
