MOTOPOWER MP69040 Car OBD2 Scanner Check Engine Fault Code Reader Diagnostic Scan Tool, Black

The sudden glow of the "Check Engine" light used to fill me with dread. I bought the MOTOPOWER MP69040 scanner hoping for a little clarity, and it has completely exceeded my expectations, transforming how I handle basic car diagnostics. Flawless Connectivity & Ease of Use: This is the definition of plug-and-play. The connector plugs snugly into the standard OBD2 port under my dash. It powers on instantly and pairs with the vehicle's computer in seconds. The buttons are intuitive, and the screen is clear and easy to read. I had it reading codes literally within two minutes of opening the box—no tech expertise required. Pinpoint Accuracy & Reliability: This isn't a guesswork gadget. The code it pulled (P0420 for Catalyst System Efficiency) was 100% accurate and matched exactly what my local mechanic's professional scanner found when I eventually took it in for repair. It reads and clears codes with authority. When it says a code is erased, the check engine light stays off, confirming the underlying issue is fixed. This accuracy gives me total confidence in its readings. Invaluable Live Data Feature: Beyond just reading stored codes, the "Live Data" function is a game-changer. I was able to monitor my engine's vital signs in real-time—things like engine coolant temperature, intake air temperature, and oxygen sensor voltages. Watching this data helped me confirm that my thermostat was operating correctly, ruling out another potential issue. It’s like having a basic health monitor for your car's engine. For the price, the functionality is incredible. It saved me from an unnecessary repair scare (a loose gas cap) and later gave me the hard data I needed to confidently discuss a real issue with my mechanic. It has more than paid for itself. If you want to take the panic out of that orange light and understand your car better, this tool is an essential purchase. Five stars!

Simple to use, no issues. I had to use it to test my battery as well which gave me an indication of a slow initial crank time for my car. Well worth it.

works great

Good little scanner. Reads OBDII DTCs, I/M rediness, live data, and can do a battery crank test. Backlighting makes it easy to read in evenings. Straightforward user interface.

Very pleased with how easy this scan tool was to use to pull DTCs, look at Freeze Frame data and also view live data. Impressed with the value.

This is a very great OBD I code reader. Works awesome. Reads code that trigger the check engine light. Very easy to use and connect to the vehicle computer system perfect size and great value for the money!

It didn’t do what I wanted it to do and was unresponsive at times, the price was good and it has a great screen that is vibrant and features like a battery tester and crank test, but I was unhappy with mine.

I bought this to test the cars reliability due to the cold snap we had and functions well for the price.

Buenísimo para borrar los fallos de adblue en los Citroën Con un bote de anticristalizante y este aparato solucionas la avería sin pasar por ningún taller. Muy sencillo de utilizar los menús se pueden poner en español

Wasn't sure whether this would be any good. Used it to check the reason why the engine management light was on. It generated an appropriate code which I looked up. Also can be used to get live data. Easy to use. Value for money

Works as it should Found problem with code. Thanks

Ottimo, funziona bene su Dacia Duster del 2012. Legge i messaggi di errore e ne nostra il significato, e li cancella facendo sparire le spie. Consigliato secondo me.

Très bon produit ! Donne le code de l’erreur ! Tres facile à rechercher sur internet par la suite 👍
