Dealing with a check engine light can be frustrating. Just when you think your car is running smoothly after a recent service, that dreaded light pops up on your dashboard. Like many car owners, I decided to take matters into my own hands and investigate the issue myself before heading to a mechanic. The solution? An OBD2 scanner. These handy devices plug into your car’s computer and tell you exactly what those cryptic engine codes mean. After some research and recommendations, I opted for the Kobra OBD2 Scanner from Amazon, drawn in by its high ratings (over 2700!) and claims of broad compatibility. This car scanner review will dive into my experience using the Kobra OBD2 scanner to diagnose my 2008 vehicle.
Setting Up the Kobra OBD2 Scanner
Like most OBD2 scanners on the market, the Kobra offers both Wi-Fi and Bluetooth connectivity. This allows it to communicate with your smartphone or tablet via a compatible app. Before you get to the app, the first step is locating your car’s OBD-II port. This is usually found under the dashboard on the driver’s side. If you have a device plugged into your OBD-II port for insurance tracking, you’ll need to temporarily disconnect it to use the scanner.
Connecting the Kobra scanner is straightforward. Since this model uses Wi-Fi, you need to connect your phone to the scanner’s Wi-Fi network through your phone’s Wi-Fi settings. Once connected to the Wi-Fi network of the OBD2 reader, you are ready to use a compatible app.
App Compatibility: A Mixed Experience
The Kobra OBD Scanner’s product description boasts compatibility with numerous OBD2 apps, including popular options like OBD Fusion, DashCommand, Torque, and Car Scanner ELM OBD2. It claims to work with both generic and manufacturer-specific Diagnostic Trouble Codes (DTCs) and support car models from 1996 to 2016. While I only tested it on my 2008 model, the 2016 cut-off for compatibility mentioned is something to note, especially if you own a newer vehicle.
However, my experience with app compatibility was not as seamless as advertised. I discovered that many OBD2 apps are designed to work exclusively with specific scanners, often their own brand. Apps like Garage Pro, FIXD, AutoDoctor, and Torque failed to recognize or connect to the Kobra scanner. This was a bit frustrating as it required some trial and error to find a compatible application.
Ultimately, I found success with the Car Scanner ELM OBD2 app on iOS. This app recognized the Wi-Fi connection of the Kobra scanner without issue. It’s important to note that many OBD2 apps primarily support Bluetooth connections, so Wi-Fi compatibility can be a limiting factor. While other apps might work, be prepared to experiment to find one that pairs with the Kobra Wi-Fi scanner.
Diving into Car Diagnostics with the Kobra Scanner
Once connected through the Car Scanner Pro app, the Kobra OBD2 scanner provides a range of diagnostic information. The app interface is user-friendly, offering options like “Dashboard,” “Live Data,” “All Sensors,” and crucially, “Diagnostic trouble codes.” Since my primary goal was to decipher the check engine light, I headed straight for the diagnostic codes.
Before exploring the error codes, let’s take a quick look at some of the other data the Kobra scanner can provide. The “Dashboard” feature offers real-time monitoring of essential engine metrics.
You can view real-time engine RPM, vehicle speed, and engine temperature, giving you a snapshot of your car’s performance. Another dashboard provides insights into fuel consumption and driving time.
Voltage information is also readily available, offering a quick check on your car’s electrical system.
Decoding Error Codes and Gaining Control
When I checked for error codes, the Kobra scanner revealed several: P2004, P0128, P0522, and P0856. The P0856 code turned out to be an inhibited test, likely a false reading. After clearing the codes and restarting my car, the persistent culprit was P2004: “intake manifold air control actuator stuck open.”
Armed with this specific error code, I could research its meaning and potential repair costs online. This knowledge proved invaluable. Instead of going into a repair shop completely in the dark, I had a clear understanding of the problem and a reasonable estimate of the repair expense. This allows for a more informed conversation with mechanics and the ability to shop around for the best price, preventing potential overcharges. While the scanner itself didn’t fix the car, it empowered me with information and control over the repair process. Knowing the issue wasn’t critical allowed me to schedule the repair when it was financially convenient.
Final Verdict: Is the Kobra OBD2 Scanner a Good Buy?
The Kobra OBD-II Scanner is available on Amazon for around $20.99. For this price, it provides a significant amount of diagnostic capability. It can potentially save you money by giving you insight into car problems before you visit a mechanic. The biggest drawback I encountered was the limited app compatibility compared to what was advertised. However, once paired with the Car Scanner ELM OBD2 app, it functioned effectively, providing valuable data and error code diagnostics.
If you’re comfortable with a bit of app experimentation and primarily need a Wi-Fi OBD2 scanner for basic diagnostics, the Kobra OBD2 Scanner is a worthwhile investment for the price. Just be aware of the potential app compatibility limitations and the 2016 vehicle model year cutoff.
