Question about 2004 Dodge Ram 3500 Truck
Who can tell me what a po243 error code "wastegate" is? What do I need to do to fix it? Took it to local dealer twice, they wipe the check engine light by the time I get home it is back. Now truck is 1000 miles out of warrenty! Go figure.
A wastegate is a valve that diverts exhaust gases away from the turbine wheel in a turbocharged engine system. Diversion of exhaust gases regulates the turbine speed, which in turn regulates the rotating speed of the compressor. The primary function of the wastegate is to regulate the maximum boost pressure in turbocharger systems, to protect the engine and the turbocharger.
It is not really a minor thing. It may not cause a major problem, but you are very likely loosing power and fuel mileage because of it.
