Exhaust Pressure Control Valve "B" Stuck Closed
DTC P04A5, sometimes indicated as P04A500 is an OBD diagnostic trouble code indicating a generic fault with the vehicle powertrain (i.e. engine and gearbox). This code identifies an error with the auxiliary emissions system causing exhaust pressure control valve "b" stuck closed.
This code is set when the exhaust pressure control valve "B" is stuck closed. This can be caused by a number of things, including a defective exhaust pressure control valve, a defective exhaust gas recirculation (EGR) valve, or a defective exhaust manifold.
If this code is being set because of a defective exhaust pressure control valve, the solution is to replace the valve. If the code is being set because of a defective EGR valve, the solution is to replace the valve. If the code is being set because of a defective exhaust manifold, the solution is to replace the manifold.
