If any tests are incomplete or have failed, you can address the underlying issues before taking the vehicle for emission testing. This can save you time and money by avoiding a failed test.

20. Understanding Fuel Trim Values

What are fuel trim values, and what can they tell you about your engine’s performance?

Fuel trim values indicate how much the engine’s computer is adjusting the fuel mixture to compensate for imbalances. There are two types of fuel trim:

• Short-Term Fuel Trim (STFT): Short-term adjustments to the fuel mixture.
• Long-Term Fuel Trim (LTFT): Long-term adjustments to the fuel mixture.

Positive fuel trim values indicate that the engine is running lean (too much air), and the computer is adding fuel to compensate. Negative fuel trim values indicate that the engine is running rich (too much fuel), and the computer is reducing fuel to compensate. By monitoring fuel trim values, you can identify issues such as vacuum leaks, faulty oxygen sensors, and fuel injector problems.

21. Diagnosing Sensor Issues with Live Data

How can you use live data to diagnose issues with sensors such as oxygen sensors, MAF sensors, and coolant temperature sensors?

Live data is invaluable for diagnosing sensor issues. Here’s how to use live data to diagnose common sensor problems:

• MAF Sensors: Monitor the MAF sensor readings to see if they are within the expected range for the current engine load. A faulty MAF sensor may show incorrect readings or a lack of response to changes in engine load.
• Coolant Temperature Sensors: Monitor the coolant temperature sensor readings to see if they are accurate. A faulty coolant temperature sensor may cause the engine to run poorly or overheat.

22. Performing an EVAP System Test

What is an EVAP system test, and how can it help you diagnose emission problems?

An EVAP (Evaporative Emission Control) system test checks the integrity of the vehicle’s fuel vapor recovery system. This system prevents fuel vapors from escaping into the atmosphere. A common EVAP system problem is a leak, which can cause a check engine light and a failed emission test. By performing an EVAP system test with the Kobra CAN OBD2 scan tool, you can check for leaks and other issues in the EVAP system.
