Dealing with a check engine light can be frustrating, especially when you’ve recently had your car serviced. Like many car owners, I decided to take matters into my own hands and explore OBD2 scanners. Following recommendations from friends and colleagues, I opted for the Kobra Obd2 Scanner from Amazon. With over 2700 ratings and promises of broad vehicle compatibility and a large code database, it seemed like a worthwhile investment to understand those cryptic error codes.
The Kobra OBD2 scanner, like most in its category, offers both Wi-Fi and Bluetooth connectivity to link with your smartphone app and relay data from your car’s computer. Before diving into app compatibility, the first step is locating your car’s OBD-II port. If you’re using a telematics device for insurance tracking, you’ll need to temporarily disconnect it to plug in the Kobra OBD2 scanner.
Installation is straightforward. Once plugged into the OBD-II port, the scanner powers up and is ready to connect to your phone. This particular Kobra model uses Wi-Fi, requiring a quick switch in your phone’s Wi-Fi settings to connect directly to the scanner’s network.
The product description for this ELM327 WIFI Scanner and Car Scan Tool boasts compatibility with all car models from 1996 to 2016 and claims to read both generic and manufacturer-specific Diagnostic Trouble Codes (DTCs). While I only tested it on my 2008 vehicle, the 2016 cutoff year is worth noting for owners of newer cars. Furthermore, the Kobra OBD Scanner advertises support for numerous apps like OBD Fusion, DashCommand, Torque, and others, available on both Apple and Google Play stores. However, my experience revealed a different reality regarding app compatibility.
I discovered that many OBD-II apps are designed to work exclusively with the app developer’s own branded scanners. Popular apps such as Garage Pro, FIXD, AutoDoctor, and Torque failed to recognize or connect to the Kobra scanner. In fact, the only app that successfully paired with the Kobra OBD2 scanner on my iOS device was Car Scanner ELM OBD-2. While other apps might be compatible, it’s important to be aware that many apps prioritize Bluetooth connections over Wi-Fi for OBD-II scanners.
The Car Scanner ELM OBD-2 app thankfully offered a Wi-Fi connection option. The default IP address and port settings worked seamlessly after initially connecting my phone to the Kobra OBD2 Scanner via Wi-Fi.
Once connected through the Car Scanner Pro app, a range of features become accessible, including real-time dashboards, live sensor data, and, crucially, diagnostic trouble codes – the reason I initially used the scanner to investigate my check engine light. Before checking the error codes, let’s explore some of the dashboard features.
The app provides real-time readings of essential engine parameters like RPM, speed, and coolant temperature.
It also tracks driving time, fuel consumption rate, and overall fuel usage, offering insights into your driving habits and fuel efficiency.
You can also monitor battery voltage, which can be helpful in diagnosing charging system issues.
When I checked for error codes, the Kobra OBD2 scanner identified 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 the car, the P2004 error, “intake manifold air control actuator stuck open,” reappeared. Researching this specific code provided valuable information about its meaning and typical repair costs from various auto shops.
Armed with this knowledge from the OBD2 scanner, you can approach your mechanic with a better understanding of the issue. It’s wise to avoid immediately revealing your diagnosis and first hear their assessment, allowing you to compare their findings and price estimates with your own research. While the Kobra OBD2 scanner didn’t directly save me money on repairs, it empowered me with crucial information and control over the repair process. Knowing the error wasn’t critical allowed me to schedule the repair at a more convenient time and budget accordingly.
The Kobra OBD-II Scanner is available on Amazon for a budget-friendly price of around $20.99, and it has the potential to save you significantly more than its cost in diagnostic fees and informed repair decisions. My primary concern is the overstated app compatibility. Finding a compatible app required more effort than expected, as it wasn’t as universally compatible as advertised.
