On some vehicles, equipped with a 6.6L diesel engine, an exhaust gas temperature sensor, at the position 2 location, may fail. If this occurs, the control system will inhibit diesel particulate filter regeneration and selective catalyst reductant (Diesel Exhaust Fluid) dosing. The Service Exhaust Fluid System or Service Emission System message will be displayed, the Malfunction Indicator Light (Check Engine Light) will illuminate, and a diagnostic trouble code related to the position 2 exhaust gas temperature sensor will be set. This special coverage covers the condition described above for a period of 10 years or 120,000 miles (193,000 km), whichever occurs first, from the date the vehicle was originally placed in service, regardless of ownership. Dealers are to replace the position 2 exhaust gas temperature sensor as necessary. The repairs will be made at no charge to the customer.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2020/MC-10178403-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2020/MC-10178403-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10178403","components":[{"id":"electrical","name":"Electrical system","parent":null},{"id":"engine","name":"Engine","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"CHEVROLET","model":"SILVERADO 2500","year_from":2016,"year_to":2016,"match":"base","vehicle_ids":["2016_chevrolet_silverado"]},{"make":"GMC","model":"SIERRA 2500","year_from":2016,"year_to":2016,"match":"base","vehicle_ids":["2016_gmc_sierra"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
