I've been struggling with a p0171 code since I've bought my car (second hand). It's a Honda hrv 2016. I've already taken to Honda service several times. They made me change the lambda sensor, maf sensor, fuel filter and still no luck. On long drives (+400km) it's turning on this code (P0171)
I was able to make readings with torque app while I was driving on this code. The 02S1eq values that normally should show "1" , are showing "2" (picture attached)
Can you guys give me some kind of direction of where to keep looking to solve this?
Thanks in advance
I've also uploaded a logfile captured with Torque of a short highway drive forcing this behaviour (above 75/80 mph) Link below https://drive.google.com/file/d/1cGT0b9kCjd8hxB42L6vUo1pgk6Mi8WYe/view?usp=sharing
Thanks all for your help!
