Engine code p0171 and p0441 - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

frscory · 02-28-2018, 12:06 AM

So i have a greddy turbo kit and got the e-tuning from shiv. He is a great guy and did an awesome job no complaint there but recently i have been getting engine code p0441 and p0171. Idling, p0171 is the only one that comes up but when cruising between 2k-3.5k i get both p0441 and p0171 together. My AFR seems fine when it does pop. I checked the pcv lines under the intake and all is good. I have a grimm speed manual boost control solenoid and a mishimoto catch can. I dont know if its that causing the leak or what. Any input would help! Thanks!

P0171 lean code.

possible exhaust leak near or before 02 sensor, cracked header

P0441 evap purge issue.

check evap purge solenoid if you have repurposed or removed evap purge solenoid you would need to disable that code, if not evap purge solenoid possible faulty or vacuum/boost leak leak

Thanks! Ill check it out when i can get a lift for the car. I have been smelling some exhaust at stops so that makes sense. I appreciate the help! I will have p0441 deleted because the manual boost control solenoid plugs in to where the evap solenoid would be plugged into.

Oh a lot of turbo guys have had blow off valve issues where it doesnt shut off correctly check it carefully

Dude sold his car and left here 3 years ago so I highly doubt you will get an answer.
