Possible OBD-II port locations

My sensor is asking for a PIN.

When connecting to the sensor on directly through the Bluetooth menu on Android devices, You may be prompted to enter a numeric pin. Use 1234. Connecting through the Bluetooth menu is optional; the FIXD app will connect to the sensor automatically.

When I try to connect to FIXD via the Bluetooth menu it tells me it is incompatible.

On iOS devices, you will see this error when trying to connect to Bluetooth Low Energy devices from the system Bluetooth menu. You do not need to connect through this menu; the FIXD app will connect to the sensor automatically.

Can I leave FIXD in my car all the time?

You can leave the sensor plugged in all the time, as it uses very little power when not communicating with the app. If you leave your car sitting for more than 3 weeks, we recommend that you remove the sensor.

Can FIXD detect my TPMS, ABS, Airbag, or other non-Check Engine lights?

FIXD can only communicate with the car about the check engine light at the moment. We are working on expanding the capabilities to include service reminders, ABS, TPMS, etc. by licensing manufacturer-specific codes.

FIXD does not recognize my VIN; what do I do?

Our VIN decoder does not always recognize vehicles sold outside the USA. VINs are 17 characters long and do not include the characters I, O, or Q. If you are having this issue contact us at

Will the sensor interfere with other Bluetooth devices in my car?

No, your smartphone will allow you to pair and communicate with multiple Bluetooth receivers at one time.

Can FIXD work without Bluetooth enabled on my phone?

No, you need Bluetooth enabled on your smartphone for FIXD to connect to the sensor and your car.

What about Windows Phone?
