Understanding OBD-II Scanners
What is an OBD-II Scanner?
An OBD-II scanner is a tool that mechanics use to diagnose car problems by accessing information from the onboard computer via the OBD port. It reads and identifies error codes, monitors systems in real-time, and predicts future issues.
What is the OBD-II Port?
The OBD-II port is a standard port in vehicles sold in the US since 1996, Canada since 1998, the EU since 2004, and Australia, Mexico, and New Zealand since 2006. It allows devices like OBD-II scanners to interface with the car’s onboard computer.
What is a DTC?
DTC stands for Diagnostic Trouble Code, an error code generated by a car’s OBD system when it detects an issue, read by OBD-II scanners to identify problems.

Deciphering Diagnostic Trouble Codes (DTCs)
DTCs consist of a letter and four numbers, indicating the car’s system experiencing the issue:
- P (Powertrain)
- B (Body)
- C (Chassis)
- N (Network)
The second character denotes a generic (0) or manufacturer-specific (1) code. The third character identifies the specific system:
- 1: Fuel and air metering
- 2: Injector circuit
- 3: Ignition system or misfire
- 4: Auxiliary emissions
- 5: Vehicle speed controls and idle control systems
- 6: Computer auxiliary outputs
- 7, 8, 9: Transmission and gearbox faults
- A, B, C: Hybrid-specific propulsion faults
The fourth and fifth characters specify the exact fault. OBD-II scanners interpret these codes, providing detailed information, though some may require additional research.
Choosing the Best OBD-II Scanner
Selecting the best OBD-II scanner involves considering key factors:
- Easy Setup: A quick setup is crucial for timely diagnostics.
- Fault Explanations: Clear explanations of fault codes are essential for understanding issues.
- I/M Readiness Check: Verifies readiness for state inspections.
- Accuracy: Accurate results are vital for effective diagnostics.
- Size and Weight: Compact and lightweight scanners are more convenient.
- Live Data: Monitors engine parameters in real-time.
- Graphs: Visual representation of data enhances analysis.
- Warranty: A long warranty ensures lasting performance.
Choose between handheld scanners with a screen and cable or wireless scanners that connect to smartphones via Bluetooth. Prioritize scanners with lifetime warranties or software updates. Consider screen size, ruggedness, and additional features like multimeters or PDF export.

How We Test OBD-II Scanners
Our testing process involves:
- Verifying the scanner’s ability to report the car’s Vehicle Identification Number (VIN).
- Connecting wireless scanners to devices via Bluetooth or Wi-Fi.
- Monitoring engine systems and disconnecting sensors to test fault detection.
- Checking the details provided by the scanner and clearing error codes.
- Evaluating the scanner’s ability to display operating data such as engine speed and coolant temperature.
By using this meticulous process, we can find the best OBD-II scanners on the market.
The Tom’s Guide team tests OBD-II scanners by connecting each scanner to the car’s OBD-II port to ensure they can report the car’s VIN. For wireless scanners, connect to devices via Bluetooth or Wi-Fi. They monitor the engine and other vital systems, and then disconnect the engine’s oil temperature sensor. Finally, they check the details provided by the scanner, fix the problem, turn off the check engine light, and erase the error code.
Understanding Fault Codes
Fault codes consist of a letter prefix:
- Powertrain (P)
- Body (B)
- Chassis (C)
- Undefined (U)
Some codes are generic (starting with 0), while others are specific to carmakers (starting with 1).
For example, a P0098 code indicates an issue with the engine’s intake air temperature sensor. In contrast, a P1112 code on a Ford means the intake air temperature sensor is reporting values intermittently and should be replaced.
