    Vehicle : SRI 150

    Trim : Smart and Bad!

    Engine : Z19DTH

    Year : 2008

    Mileage : 105000

    Default fault codes DPF and Air intake Leak

    Got 2 fault codes coming up now.

    P1901-75 for Particulate Filter Pressure Sensoor High Differential Pressure

    and P2279-11 Intake Air System Leak Detected

    I cannot find this leak as i checked it all over the intake and no leaks as far as i can see. used washing up liquid as i use the same thing for finding gas leaks as a plumber.

    Any assistance? would help a lot!

    I have resetted the PFP as it was at 110% and blueish smoke but no oil or water or fuel smell in the smoke, just emission smell. so i know no seals are lost or water in fuel or overfuel burn.

    Clean the egr valve as that code also comes up when it doesn't fully close.

    The egr valve been deep cleaned 200 miles ago. The inner valve opens and closes with smooth ease.

    I checked with my computer and reset the fpf it was at 110% so way over where it should be at!!

    I reset it to 0% to get more acuate reading. Tomorrow i'll check then after a drive.

    Can someone tell me the areas the intake air hoses as i checked, cant find any leaks so i might be missing one more hose??
