- Connected scan tool and checked for codes. Light off, but codes are stored for idle control higher than expected (P0507) and fuel trim on bank 1 (P0171). Test drove vehicle and monitored live data. Vehicle running normally, but fuel trims are too high. Suspect an air leak in intake system. Removed engine covers and air filter housing. Smoke checked vehicle, found a leak coming from turbocharger inlet hose after MAF. Inspected hose, found large crack in side of hose. Recommend replacement of hose prior to further diagnosis. Removed intake piping and hose. Replaced hose with new unit. Reassembled intake piping. Cleared codes and test drove vehicle. No codes stored or pending, and live data no longer shows lean conditions from unmetered air. Reinstalled engine covers and test drove a second time. No idle surging or hunting present and no check engine light or codes.
