Does your scan tool allow you to see the fuel trim readings?

Customer reply replied 7 months ago
If you're asking about the time frame, yes you can see it, if the fuel trim readings is something else on the scanner I don't think so
Auto Mechanic: FixItMan, Master Technician replied 7 months ago

On the sensor data you should see something that looks like "LTFT" or "STFT". This would help to diagnose this issue.
