The hazard
On certain buses equipped with Detroit Diesel series 50 engines, the turbocharger can fail, allowing lubricating oil to enter the exhaust system. This can result in an engine compartment fire, possibly resulting in personal injuries. Correction: Dealers will reprogram the Electronic Control Module (ECM) to enable the exhaust temperature sensor.
