Displays Data Logs

The OBDScar OS601 OBD II code reader can display logged data like gas mileage readings or RPM levels.

Displays Live O2 Sensor Test

Monitoring your O2 sensor is an excellent way to be on top of your car's exhaust performance. Bad O2 sensor performance can decrease vehicle performance, foul odors from the exhaust, and poor gas economy. It can also mean failing the emissions test. Knowing how your O2 sensor saves you money and trouble.

Displays Evap System Test Data

If the vehicle's evaporative system is not working correctly, it can cause a buildup of gas vapors in the fuel tank. These vapors are dangerous because they could ignite and explode. OBDScar OS601 OBD II code reader can immediately diagnose your car's evap system and help you get back on track with proper management.

Among the data that you can get from the evaporative system test data are mass airflow (MAF), intake air temperature (IAT), vehicle speed (VSS), and engine coolant temperature (ECT) sensors.

OBDScar OS601 OBD2 Scanner FAQ

Do OBD2 scanners work on all cars?

Since the OBD2 protocol started only in 1996, only US vehicles manufactured from this date can use the features of OBD2 scanners. However, some advanced scanners can scan OBD1 cars with the right accessories.

What is the difference between OBD and OBD2?

Both are protocols designed to diagnose car performance, but OBD1 is the earlier version that needs to be connected to the car's console so it can work. OBD1 is for vehicles manufactured in the 80s and the early 90s.

The OBD2, on the other hand, is the more modern version of OBD1 with more features and capabilities.  It also works for US cars made from 1996, EU cars made from 2001, and Asian cars from 2008.


The OBDScar OS601 is an affordable device that can diagnose vehicle problems quickly and efficiently. It's compatible with most OBD2 protocols, so you're sure to find a solution to your car problem. Whether it's a check engine light or something more serious like the dreaded P0401 code, this scan tool will help pinpoint what you need to fix and how much you will spend.
