Dealing with a check engine light can be frustrating, especially when your car was recently serviced. Like many car owners, I experienced this recently with my 2008 vehicle. Instead of immediately rushing to a mechanic, I decided to explore a more DIY approach based on recommendations from friends and colleagues: using an OBD2 scanner. These handy devices can help you decipher those cryptic error codes and potentially save you time and money. After some research, I opted for the Kobra OBD2 Scanner from Amazon, drawn in by its high ratings (over 2700!) and promises of a vast code database and broad vehicle compatibility.
The Kobra OBD2 scanner, like most of its kind, offers two primary connection methods: Wi-Fi or Bluetooth. These connections bridge the gap between the scanner plugged into your car and a user-friendly mobile app on your smartphone. Before diving into the app experience, let’s first locate your car’s OBD-II port. If you’re already using an OBD-II device for insurance tracking, you’ll need to temporarily disconnect it to plug in your new scanner. This port is usually located under the dashboard on the driver’s side.
Once the Kobra OBD2 scanner is securely plugged into the OBD-II port, it should power on automatically. This particular model utilizes a Wi-Fi connection. To establish this connection, navigate to your phone’s Wi-Fi settings and select the OBD2 reader’s network. This step is crucial for enabling communication between your phone and the scanner.
My experience with the Kobra OBD2 reader was limited to my own vehicle, but the product description boasts broad compatibility, claiming to support all car models manufactured between 1996 and 2016. It’s worth noting the 2016 cutoff, which raises questions about compatibility with newer vehicles. The Kobra OBD Scanner also advertises compatibility with numerous OBD2 apps available on both the Apple App Store and Google Play Store, including popular choices like OBD Fusion, DashCommand, Torque, and Car Scanner ELM OBD-2. However, my testing revealed a slightly different reality regarding app compatibility.
I discovered that many OBD-II apps are designed to primarily work with specific OBD-II scanners, often those produced by the app developers themselves. Surprisingly, apps like Garage Pro, FIXD, AutoDoctor, and Torque, among others, failed to recognize or connect with the Kobra OBD2 scanner. The only app that successfully connected and functioned seamlessly with the Wi-Fi-based Kobra scanner on my iOS device was Car Scanner ELM ODB-2. While other apps might offer compatibility, it’s important to be aware that many favor Bluetooth connections over Wi-Fi for OBD-II scanners.
The Car Scanner ELM OBD-2 app proved to be user-friendly and readily offered a Wi-Fi connection option, which was essential for the Kobra scanner. The default IP address and port settings worked without any adjustments after successfully connecting my phone to the Kobra OBD2 scanner via Wi-Fi.
Once connected via the Car Scanner Pro app, a range of options become available, including “Dashboard,” “Live Data,” “All Sensors,” and, most importantly in my case, “Diagnostic Trouble Codes.” My primary goal was to understand why my check engine light was illuminated. Before delving into the error codes, let’s briefly explore some of the other valuable features offered through the app interface.
The “Dashboard” feature provides real-time insights into your vehicle’s performance, displaying metrics like engine RPM, speed, and engine temperature. This live data can be incredibly useful for monitoring your car’s health while driving.
Another helpful dashboard displays information related to fuel consumption, including drive time and fuel usage. This can assist in optimizing driving habits for better fuel efficiency.
The app also provides access to voltage information, allowing you to monitor your car battery’s health and charging system performance.
Turning back to the diagnostic trouble codes, the Kobra OBD2 scanner revealed several error codes in my vehicle: P2004, P0128, P0522, and P0856. The P0856 code was identified as an “inhibited test,” likely a false reading. After clearing the codes and restarting my car, the P2004 error, indicating an “intake manifold air control actuator stuck open,” persistently reappeared. Researching this specific code provided valuable information about its meaning and potential repair costs from various auto shops.
This knowledge empowers you when visiting a car repair shop. By having pre-scan information, you can compare the mechanic’s diagnosis and estimates with your own findings. This allows for more informed decisions and the potential to shop around for better prices if needed. While the Kobra OBD2 scanner didn’t directly fix my car, it provided a sense of control by revealing the issue and its severity. Knowing the error wasn’t critical allowed me to schedule the repair at a more convenient and budget-friendly time.
The Kobra OBD-II Scanner is available on Amazon for a reasonable price of around $20.99. This small investment can potentially save you significantly more than its cost by providing valuable diagnostic information. My primary critique is the overstated app compatibility. Finding a compatible app took longer than expected. However, once paired with the Car Scanner ELM OBD-2 app, the Kobra OBD2 scanner proved to be a useful tool for understanding and addressing car issues.
