Post by: mk3tony on 28 January 2012, 12:53

Been having the 17544 p1136 bank 1 code and I know its not maf as its brand new genuine from stealers. Dont think it can be pcv as have catch can, I know I have a boost pipe loose so am ordering a 5 piece kit. Just need to know if its just this boost pipe thats throwing it?

Could be anything below. So sort out all your leaks

17544/P1136/004406 - Fuel Trim: Bank 1 (Add): System too Lean

Possible Solutions

    Check Mass Air Flow (MAF) Sensor
    Check Fuel Pressure Regulator
    Check Fuel Pump
    Check Intake/Exhaust System for Leaks
    Check Secondary Air Injection for Leaks
    Check Vacuum Lines for Leaks

But could also be the lambda sensor

I know i've been through that list thats why I need someone to test for leak, vacuum, boost amd exhaust. Where can the secondary air intake leak? I've just got the hose hanging loose and not connected as got a filter on maf.
