A seemingly simply lean condition on a Honda Pilot that does not present as you are used to!

I think the ecu needs to discharge the capacitors.
disconnect the battery maybe it's came back to normal condition.
Another good video Matt!

Is probably not a communication problem but you are looking at the fuel trim algorithm adjusting long term setting when there is a sudden massive change in settings: the algorithm doesn't instantly changes these settings but it will take a while. Here also it would make sense to reboot power cycle the ecm so that it will relearn the long term fuel settings ( all history is gone after power cycle)
I have seen ethanol blended fuels do some weird things with fuel trim numbers.
HI FRIEND WHILE THE TRANSLATION IS ON YOUR VIDEO DOESN'T SHOW SUBTITLES IF YOU CAN WATCH IT MAYBE SOMETHING IS STUCK.THANKS
The reason that your trims didn't go down at higher RPM's is because the air leak is ahead of the throttle body and isn't a vacuum leak, it's unmeasured are after the MAF sensor.
I noticed there was two 'engine RPM' s selections on the scanner. Why would that be?
LTFT is a learned value so it might take a while to adjust depending on the car. Generic OBD is better to diagnose fuel trim problems. As cars get more complex enhanced data gets harder to read due to the growing number of data pids
Hi Matt do you own or tried autel oscilloscope is it any good? Also is there a pressure transducer that goes with it or not. Thanks
