P005E obd2 fault code and how to troubleshoot it
Shown here is P005E obd2 code and it's general meaning. This code applies to engine turbocharger waste gate solenoid wirings that control turbo boost pressure. For a detailed brief description of any particular OBD2 fault code, please scroll below.
P005E Engine Turbocharger-Supercharger Boost Control fault code
The above code refers to the control ground voltage supplied by the engine computer to activate either the turbocharger or supercharger waste gate solenoid (in case of the turbo-charged engine) when reducing turbo boost pressure. When the ground voltage is supplied, a waste gate solenoid is turned on allowing the turbo waste gaste door to open that makes the exhaust gas reduced allowing the turbo compressor wheel to slow down.
This control mechanism is helpful in preventing engine damage in case turbo exhaust gas flow is too much. This is the basic concept of turbo boost control. (A detailed description of the fix will be supplied by ATS when the engine problem symptoms are given by ATS customers).
Turbo boost wastegate control is done in various ways like using internal flapper valve inside the turbo housing. Other boost control are also used whereas no wastegate is utilized but a remote exhaust runner passage is constructed in the exhaust manifold itself (external type turbo boost
control). However, most of these control systems are best monitored by the engine computer by grounding the waste gate solenoid so escape for the exhaust gas can occur.
Basic turbo FACTS for DIYS:
Turbochargers use a device called a wastegate system, which bypasses exhaust gas past the turbo when a certain boost limit is attained and safeguards the engine from too much boost. The typical boost provided by a turbocharger is 6 to 8 pounds per square inch. Since normal atmospheric pressure is 14.7 PSI at sea level, you will notice that you are getting about 50 percent more air into the engine.
allow the engine to burn more fuel and air mixture by forcing more mixture into the cylinders . In short, the fuel and air mixture in the compression chamber has greater higher pressure than in a normal engine. Another advantage to turbochargers is the incredible number of units available. This means the size of the turbo can be easily matched to the demands and configuration of the engine.
When boost pressure is modified to a scale higher than OEM standard on a turbocharged car, a boost gauge is required. You can do simple procedures to increase factory boost
levels. Some car makers have sought to fix the problem of turbocharger lag by using two tiny, sequential turbos rather than a large unit. The smaller turbochargers works faster because less inertia is required to overcome, and still deliver the same effect rather than at full-boost pressure like a single bigger turbocharger.
