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 again. Like many car owners facing this issue, I decided to take matters into my own hands. Following recommendations from friends and colleagues, I opted to get an OBD2 scanner. My choice? The Kobra OBD2 Scanner from Amazon, a device boasting thousands of positive ratings and compatibility with various car models and OBD2 apps.

OBD2 scanners are incredibly useful tools for car owners. They allow you to read Diagnostic Trouble Codes (DTCs) from your vehicle’s computer, giving you insight into potential problems. The Kobra OBD2 scanner, like most, offers both Wi-Fi and Bluetooth connectivity options to link with your smartphone app. Before diving into app specifics, let’s first get the scanner physically connected to your car. You’ll need to locate your car’s OBD-II port. If you’re using a device for insurance tracking that plugs into this port, you’ll need to temporarily disconnect it to use the Kobra scanner.
Once you’ve plugged the Kobra OBD2 scanner into the OBD-II port, it should power on and be ready to connect to your phone. This particular Kobra model utilizes Wi-Fi. To establish a connection, navigate to your phone’s Wi-Fi settings and select the Kobra OBD2 scanner’s Wi-Fi network.
The Kobra OBD2 scanner is advertised as an ELM327 WIFI Scanner and Car Scan Tool, claiming compatibility with generic and manufacturer-specific DTCs for car models from 1996 to 2016. While I’ve only tested it on my 2008 model, it’s worth noting the listed cut-off year. Furthermore, the product description suggests broad app compatibility, including popular choices like OBD Fusion, DashCommand, Torque, OBD Link, ScanMaster Lite, and OBD Car Doctor. However, my experience indicated that this claim might be outdated.
I discovered that many OBD2 apps are designed to work exclusively with “their own” branded scanners. Apps like Garage Pro, FIXD, AutoDoctor, and Torque, among others, failed to recognize or connect to the Kobra device. In fact, the only app that successfully paired with the Wi-Fi-based Kobra OBD2 scanner on my iOS device was Car Scanner ELM ODB-2. While other apps might potentially work, be aware that most commonly favor Bluetooth OBD2 scanners over Wi-Fi.
The Car Scanner ELM ODB-2 app thankfully offered a Wi-Fi connection option. As mentioned, most apps default to Bluetooth, making this a key feature for Kobra users. The default IP address and port settings worked seamlessly upon connecting my phone to the Kobra OBD2 scanner via Wi-Fi.
Once connected within the Car Scanner Pro app, a range of options becomes available, including Dashboard, Live Data, All Sensors, and crucially, Diagnostic Trouble Codes. My primary goal was to decipher the check engine light, so DTCs were my focus. Before we delve into the codes themselves, let’s briefly explore some of the other valuable dashboards the app provides.

The real-time data dashboards are incredibly informative. You can monitor engine RPM, vehicle speed, and engine temperature as you drive.
Further dashboards provide insights into driving duration, fuel consumption, and fuel usage.

You can even check your car’s voltage information, which can be helpful in diagnosing battery or alternator issues.
Turning back to error codes, my scan revealed codes P2004, P0128, P0522, and P0856. The P0856 code turned out to be an “inhibited test,” essentially a false reading. After clearing the codes and restarting my car, the persistent code was P2004: “intake manifold air control actuator stuck open.” Researching this code provided not only its meaning but also estimated repair costs from various mechanics.
This knowledge is power. Armed with this information, you can approach your mechanic with a better understanding of the problem. Consider getting a diagnosis from your usual repair shop without revealing your scan results initially. Compare their findings and price estimates with your research. If you feel the quote is too high, you can confidently seek second opinions and potentially save money by choosing a more competitive shop. While the Kobra OBD2 scanner didn’t directly fix my car, it gave me crucial control and understanding of the situation. Knowing the issue wasn’t critical allowed me to schedule the repair when it better fit my budget.
The Kobra OBD2 Scanner is available on Amazon for a reasonable price of around $20.99. This small investment can potentially save you significantly more in unnecessary diagnostic fees and repairs. My main drawback was the app compatibility issue; it required more effort than expected to find a suitable app. However, once paired with the Car Scanner ELM ODB-2 app, the Kobra OBD2 scanner proved to be a valuable tool for car troubleshooting.
