Oxygen sensors play a key role in engine performance and keeping emissions under control. Their purpose is to measure the amount of oxygen in the exhaust, providing your vehicle's computer with information whether the air/fuel mixture is burning rich (less oxygen) or lean (more oxygen). If an oxygen sensor goes bad, it can damage the catalytic converter (a very expensive fix!), reduce fuel efficiency, and substantially increase the amount of harmful pollutants in the exhaust.
Using OBDLink's logging feature, you can graph the transitions of each oxygen sensors’ voltage (usually there are 2 sensors but some vehicles have up to 4), and know when one becomes faulty. Continue reading
There are 3 main jobs that the antifreeze in coolant performs to keep the engine coolant temperature normal:
- It prevents the coolant from freezing during cold weather
- It raises the boiling temperature of the coolant to prevent overheating during hot weather
- It fights corrosion
Does your state require an emissions check before renewing your registration? These checks verify that your vehicle is not putting harmful vapors into the air. Most states now use an OBD-II test to confirm your vehicle is not violating standards required by the U.S. Environmental Protection Agency (EPA).
To pass an OBD-II emissions test, a vehicle must:
- Have a functional 'Check Engine' light and OBD port
- The 'Check Engine' light must be off
- Successfully complete the OBD-II system monitors that are built-in to the vehicle

OBDLink v3.4.0 Release Notes
- Improved the PID selector dialog and added search functionality
- Improved Dropbox CSV file syncing
- Improved support for some vehicles that don't fully conform to the OBD2 specification
- Added Hebrew language support
- Various improvements and bug fixes
When the Check Engine light is illuminated, your vehicle's on-board diagnostic system is telling you that there is a potential problem with your engine or transmission. The severity of the problem can very from innocuous (like a loose gas cap) to something that can cause the failure of a critical component.
Generally, you can tell whether the problem requires immediate attention, just by looking at the Check Engine light:
- A steady light typically indicates a problem with the emission control system: bad oxygen sensor, a loose gas cap, etc.
- A flashing light indicates a serious problem like a misfire, which should be taken care of right away to avoid expensive repairs.
You can use OBDLink to read out the trouble codes that will help you pinpoint the source of the problem, research the severity, and discover potential fixes. Once you make the repairs (or tighten the gas cap), you can use the scan tool to clear the trouble codes and turn off the Check Engine light.
