CarSense app icon

Your check engine light, decoded.

AI-powered diagnostics for any car.

CarSense pairs with most ELM327-compatible Bluetooth LE (BLE) OBD2 adapters and turns cryptic trouble codes into plain-English explanations — what's wrong, how urgent it is, and what the fix typically costs.

Features

No more guessing what your car needs.

Built for drivers who want straight answers, not mechanic jargon or hand-wavy "check engine" advice.

🤖

AI diagnoses, not just code lookups

Other OBD2 apps just show a generic definition for P0420. CarSense explains what's likely happening on your exact make, model, and year — including documented quirks and known issues.

💰

Honest cost estimates

Every diagnosis includes a realistic repair cost range based on industry data, broken down by likely cause. No more walking into a shop blind.

🔧

Severity that actually means something

Get a clear severity rating — Safe, Monitor, Urgent, or Critical — plus driveability advice. Know whether you need to pull over or whether it can wait until next service.

📚

Manufacturer service bulletins included

When the NHTSA has a documented Technical Service Bulletin matching your code and vehicle, CarSense surfaces it — the same fix the dealership would reference.

🛡️

Works with most ELM327 Bluetooth LE adapters

Bring your own ELM327-compatible Bluetooth LE adapter — no proprietary hardware lock-in. Built and tested with the Veepeak OBDCheck BLE+ (~$40), our recommended adapter; also designed to support Vgate iCar Pro, OBDLink, and other common ELM327 BLE dongles.

🔍

Pre-purchase scan

Buying a used car? Run a full pre-purchase scan and get a buy / caution / walk-away verdict, with negotiation points based on what's actually wrong.

How It Works

Three taps from "check engine" to "here's the fix."

1

Plug in your adapter

Plug an ELM327-compatible Bluetooth LE OBD2 adapter into your vehicle's OBD2 port. Turn the ignition to "Run" so the adapter powers on.

2

Scan codes

Open CarSense. The app auto-discovers nearby BLE adapters. Select your vehicle and tap Scan Codes.

3

Read the diagnosis

Get a plain-English explanation tailored to your year/make/model — likely causes, severity, cost range, and DIY-friendliness.

4

Decide your next move

Drive on, fix it yourself, or find a verified shop nearby. CarSense shows quotes from local mechanics for the exact repair.
