Exhaust Pressure Control Valve A Stuck Open at Russell Hixson blog

Exhaust Pressure Control Valve A Stuck Open. Exhaust pressure control valve ‘a’ stuck open indicates that the exhaust pressure control valve is stuck in the open. A stored code p047f means that the powertrain control module (pcm) has detected a malfunction in one of the exhaust pressure control. You remove the flapper assembly and spray it while wiggling it until it moves freely, reinstall and clear codes if you can. Inspect the exhaust pressure control valve 'a' and its wiring for any visible damage or corrosion. The first error is a communication problem (i assume the restraint control module is used for seatbelt information for stopstart). The p047f fault code refers to the exhaust pressure control valve ‘a’ being stuck open. If no obvious wiring or connector problems are found, start by testing the expected voltage signal at the exhaust pressure control. This valve is responsible for controlling the exhaust back pressure during cold temperatures to increase cab heat and defrost the windshield more quickly. Verify the mechanical part of the exhaust valve. This fault code may show up in combination or shortly after flashing the engine control module.
