Is your car’s check engine light stubbornly glowing, causing you stress and uncertainty? Like many car owners, I recently faced this frustrating situation. My 2008 vehicle, despite a recent service, decided to illuminate that dreaded light. Instead of immediately rushing to a mechanic and facing potentially hefty bills, I decided to explore a modern solution: an OBD2 scanner. Following recommendations from friends and colleagues, I opted for the KOBRA Wireless OBD2 Car Code Reader Scan Tool from Amazon, drawn in by its high ratings (over 2700!) and promises of wide vehicle compatibility and a vast code database. This review dives into my experience with the KOBRA scanner to help you decide if it’s the right tool to diagnose your car troubles.

OBD2 scanners are invaluable tools for modern car diagnostics, allowing you to understand what’s happening under the hood without needing to be a mechanic. The KOBRA scanner, like most, offers both Wi-Fi and Bluetooth connectivity options to link the device to your smartphone and utilize OBD2 applications. Before you begin, you’ll need to locate your car’s OBD-II port. It’s usually located under the dashboard on the driver’s side. If you use a device for insurance tracking that plugs into this port, you’ll need to temporarily disconnect it to use the KOBRA scanner.
Once plugged in, the KOBRA scanner powers up and is ready to connect to your phone. This model uses Wi-Fi, so you need to go into your phone’s Wi-Fi settings and connect to the OBD2 reader’s network. The process is straightforward, similar to connecting to any Wi-Fi network.
The KOBRA OBD2 scanner is advertised as an ELM327 WIFI Scanner and Car Scan Tool, claiming compatibility with all car models from 1996 to 2016 and capable of retrieving both generic and manufacturer-specific Diagnostic Trouble Codes (DTCs). While I only tested it on my 2008 model, the product description suggests broad compatibility within that timeframe. However, the claim of supporting numerous mobile apps, including popular ones like OBD Fusion, DashCommand, and Torque, needs closer examination.
I discovered that app compatibility wasn’t as seamless as advertised. Many OBD2 apps are designed to work exclusively with specific scanners, often Bluetooth-based models. Apps like Garage Pro, FIXD, and AutoDoctor, among others, failed to recognize or connect to the KOBRA Wi-Fi scanner. Frustratingly, many apps prioritize Bluetooth connections, leaving Wi-Fi scanners like the KOBRA somewhat isolated. However, I did find success with the Car Scanner ELM ODB-2 app from the iOS App Store.
The Car Scanner ELM OBD-2 app thankfully offered a Wi-Fi connection option, which worked flawlessly with the KOBRA scanner using the default IP/port settings. This app became my interface to the wealth of data the KOBRA scanner could access from my car’s computer.
Once connected through the app, you gain access to various features, including a customizable Dashboard, Live Data monitoring, All Sensors readings, and crucially, Diagnostic Trouble Codes. My primary goal was to decipher the check engine light, so I immediately navigated to the diagnostic trouble codes section. But before we delve into the error codes, let’s explore some of the other helpful dashboards the app provides.

The dashboard feature provides real-time insights into crucial engine parameters like RPM, speed, and temperature. This live data is incredibly useful for monitoring your car’s performance as you drive.
Another dashboard offers information on drive time, fuel usage, and fuel consumption. This can help you track your driving habits and fuel efficiency, potentially leading to savings at the pump.

You can also check voltage information, which is helpful for monitoring battery and charging system health. These dashboards provide a wealth of information beyond just error codes, making the KOBRA scanner a versatile tool for car owners.
However, the main reason I purchased the KOBRA scanner was to understand those pesky error codes. My scan revealed codes P2004, P0128, P0522, and P0856. The P0856 code turned out to be an “inhibited test,” likely a false reading and not a real issue. After clearing the codes and restarting my car, the P2004 “intake manifold air control actuator stuck open” error reappeared. Researching this code provided not only its meaning but also estimated repair costs from various mechanics.
Armed with this knowledge, I visited my local car repair shop. Crucially, I didn’t reveal that I had already diagnosed the issue. This allowed me to compare their diagnosis and price estimate with my own findings. While the KOBRA scanner didn’t magically fix my car, it empowered me with information and control. Knowing the problem wasn’t critical allowed me to budget and schedule the repair at a convenient time, rather than panicking and rushing into potentially overpriced immediate repairs.
The KOBRA ODB-II Scanner is available on Amazon for a reasonable price of around $20.99. While my experience highlighted a slight overstatement of app compatibility, the scanner itself performed its core function effectively. The ability to diagnose car issues yourself can potentially save you significantly more than the scanner’s cost in the long run. If you’re looking for an affordable entry into DIY car diagnostics, the KOBRA Wireless OBD2 Car Code Reader Scan Tool is a worthwhile investment.
