# Service bulletin TSB 19\-2029 A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned. - Type: Service bulletin - NHTSA id: 10156864 - Published by NHTSA: 2019\-04\-08 - Manufacturer's number: TSB 19\-2029 - Manufacturer's date: 2019\-02\-11 - NHTSA component: ENGINE AND ENGINE COOLING:EXHAUST SYSTEM:MANIFOLD/HEADER/MUFFLER/TAIL PIPE ## NHTSA's summary Some 2017\-2019 F\-Super Duty vehicles equipped with a 6.7L engine built on or before 9\-Jan\-2019 may exhibit an illuminated malfunction indicator lamp \(MIL\) with DTCs P2074 and/or P0170. Follow the Service Procedure steps to correct the condition. ## The document - [NHTSA's copy of the document (PDF)](https://static.nhtsa.gov/odi/tsbs/2019/MC-10156864-0001.pdf) - [If that address does not open, try this one](https://static.nhtsa.gov/odi/tsbs/2019/MC-10156864-9999.pdf) The document is the manufacturer's.

Some 2017\-2019 F\-Super Duty vehicles equipped with the 6.2L engine may exhibit an illuminated malfunction indicator lamp \(MIL\) with diagnostic trouble codes \(DTCs\) P2004 and/or P2005. This may be due to a tear or crack on the intake manifold vacuum hoses resulting in a vacuum leak. Before performing normal diagnostics, inspect the intake manifold vacuum hoses. If a tear or crack is identified, intake manifold assembly replacement is not required. The vacuum hose assemblies are available as a lower level service part \(base part 9E498\). - [SSM 47641](/bulletins/10152467.md), 2019-01-07, Service bulletin: ENGINE AND ENGINE COOLING:EXHAUST SYSTEM:EMISSION CONTROL:GAS RECIRCULATION VALVE \(EGR VALVE\); ENGINE AND ENGINE COOLING:EXHAUST SYSTEM:MANIFOLD/HEADER/MUFFLER/TAIL PIPE. Some 2011\-2019 F\-Super Duty, 2015\-2019 Transit, 2016\-2019 F\-650/F\-750 and 2018 F\-150 vehicles equipped with a 6.7L, 3.2L or 3.0L engine may exhibit an illuminated MIL with diagnostic trouble codes \(DTCs\) P207F, P20EE, P229F, P2201 and/or P24AE. This may be a result of using aftermarket cleaning liquids or tools for the exhaust gas recirculation \(EGR\) cooler or intake. Ford does not recommend the cleaning of diesel intakes or EGR coolers using any aftermarket tool that injects a cleaning foam or liquid substance into the EGR cooler or intake. Using these types of fluids can result in sodium poisoning of the NOx and particulate matter \(PM\) sensors resulting in degraded operation and permanent damage to the aftertreatment system. Use of these cleaning tools may void the emissions warranty of the hot end aftertreatment exhaust system and the attached emissions sensors. - [SSM 46085](/bulletins/10109070.md), 2017-08-01, Service bulletin: ENGINE AND ENGINE COOLING:EXHAUST SYSTEM:EMISSION CONTROL; ENGINE AND ENGINE COOLING:EXHAUST SYSTEM:MANIFOLD/HEADER/MUFFLER/TAIL PIPE; ENGINE AND ENGINE COOLING:EXHAUST SYSTEM:EMISSION CONTROL:CATALYTIC CONVERTOR; ENGINE AND ENGINE COOLING:EXHAUST SYSTEM:EMISSION CONTROL:GAS RECIRCULATION VALVE \(EGR VALVE\); ENGINE AND ENGINE COOLING:ENGINE:OTHER FUEL TYPES:TURBO/SUPERCHARGER; ENGINE AND ENGINE COOLING:COOLING SYSTEM:HOSES/LINES/PIPING/FITTINGS; ENGINE AND ENGINE COOLING; ENGINE AND ENGINE COOLING:COOLING SYSTEM:RADIATOR ASSEMBLY; ENGINE; ENGINE AND ENGINE COOLING:EXHAUST SYSTEM:EMISSION CONTROL:CRANKCASE \(PCV\); ENGINE AND ENGINE COOLING:COOLING SYSTEM; ENGINE AND ENGINE COOLING:ENGINE:GASOLINE:TURBO/SUPERCHARGER; ENGINE AND ENGINE COOLING:ENGINE:DIESEL; ENGINE AND ENGINE COOLING:EXHAUST SYSTEM; ENGINE AND ENGINE COOLING:ENGINE:GASOLINE; ENGINE AND ENGINE COOLING:ENGINE:GASOLINE:BELTS AND ASSOCIATED PULLEYS; ENGINE AND ENGINE COOLING:ENGINE; ENGINE AND ENGINE COOLING:COOLING SYSTEM:FAN. The Powertrain Control/Emissions Diagnosis \(PC/ED\) manual has been revised for diagnosing electronic throttle bodies \(ETBs\). The ETC\_ACT and ETC\_DSD PIDs should not used to diagnose possible ETB concerns. The IDS has a limited refresh rate when reading these PIDs and cannot display quickly enough to validate a concern. The PCM automatically monitors these inputs more accurately and will set diagnostic trouble codes \(DTCs\) when appropriate. Using these PIDs for diagnostics will lead to inaccurate results and improper ETB replacements. If a concern is intermittent and no DTCs are present, refer to historical DTCs and the PC/ED, Section 3 No DTCs Present Index chart for further information.
