This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation. Our certified mobile mechanics can come to your home or office to perform the Check Engine Light is on diagnostic inspection. This code has varied definitions as provided by the manufacturer. Generally, the Engine Control Unit ECU has detected an out of range reading in the turbocharger or supercharger boost control circuit. This code is related to circuit A and an area of the system circuit, as opposed to a particular malfunction or component.

Loose, corroded, or disconnected electrical connectors in the boost sensor's 5-volt reference circuit. Turbo failure from internal oil leaks and oil supply problems, causing bearing failure and blade damage. The Check Engine Light would then come on once the ECM has seen that the solenoid circuit has gone out of specifications.

The code is normally preceded by the Check Engine Light coming on the dash. The mechanic must use an OBD-II scanner to identify the code, then reset the code and test the vehicle to see if the code returns. Inspect the turbo or super charger system for loose connections, including hoses and lines being cracked or damaged.

Inspect the wiring on the boost sensor and related wiring for loose connections, damaged wiring, or faulty sensor. Check the boost pressure during operation and driving for normal range of 9 to 14 PSI pressure and ensure it is not erratic. Inspect the turbo charger for damaged blades, wobbly shaft rotation, worn bearings, oil leaks into turbo boost side, and correct control valve or waste gate operation.

Components should not be assumed to be bad and replaced without carefully inspecting the system first. Some mechanics have reported that failure to flush all debris and obstructions from the turbocharger oiling system can lead to repeated turbo failure. Turbocharger replacement without complete testing of the by-pass valve or waste gate function and electrical circuitry is also the cause of common misdiagnosis. This code is very serious.

It is usually preceded by the engine warning light coming on, and it must be diagnosed as soon as possible to prevent engine internal damage. Minimize your driving until the problem can be repaired. The vehicle can run roughly, backfire, have rich or lean fuel consumption, and operate in over or under boost conditions.

Often times, if the engine warning light comes on immediately at start up, the OBD- II system can be reset and the vehicle will operate normally. This code indicates that the operation range and performance is not being achieved, but it has many potential causes for the general problem, so the mechanic will have to do many tests in order to find the true cause and path to repair, before repairing or replacing any components, or assuming that the issue is solely due to a vacuum or oil leak, or bad wiring or connectors.

If the vehicle has been running erratically and the boost gauge operates in coordination with the running conditions, then the mechanic should check closely for obvious leaks on the intake system after the turbo such as hoses, clamps, the intercooler and piping, when the vehicle is just sitting off or at idle.

The problem may not be obvious as it usually happens when the engine is under load. I have seen a cracked hose going to a throttle body that was cracked on the bottom, where I could not see or feel it; the crack opened and closed depending on the load.

As the boost pressure increased, then the crack would open like a bladder valve and release pressure, but it operated normally under light loads.

This problem can be elusive but does require perseverance to find it. Many vehicles with mileage overhave momentary sensor problems that usually occur during start up or prolonged stress situations on the drive train. If the engine warning light comes on and the vehicle seems to be operating normally, the OBD-II system can be reset using the scanner and the problem may not reoccur. This is why it is important to verify the fault and reset it before doing any repairs.

The auto repair labor rates vary by location, your vehicle's make and model, and even your engine type. P Description The turbocharger has nozzle vane which opens and closes to control the volume of the exhaust gas flowing into the turbine.

This, in turn, controls the boost pressure, when the nozzle vane moves towards the closing direction, the pressure increases. When the vane moves towards the opening direction, the pressure decreases.
