P0243 OBD Error Code: Problem & Solutions

<<See All OBD Codes

The definition of the P0243 error code is Turbocharger Wastegate Solenoid A Malfunction. It is a generic OBD-II code which would indicate that the engine control module discovered that the turbocharger wastegate solenoid has an open or short circuit.

This trouble code is generic, which would mean that it can apply to all the vehicles which are equipped with the OBD-II or the vehicles which are made since 1996 up to the present. The specifications on the definition, the troubleshooting steps as well as repairs can always vary from one vehicle make to another.

Searching some more information about P0243 code? Then you have arrived at the correct place. The wastegate solenoid would allow the unneeded boost generated by the turbo or the supercharger to vent the system. The wastegate solenoid is controlled by the engine control module. This fault code would start triggering up if the engine is not able to control the solenoid. The turbo or the supercharger may also be disabled by the powertrain control module so that it can prevent the system from getting further damaged.

What causes this problem with the Turbocharger Wastegate Solenoid A Malfunction?

• The turbocharger wastegate solenoid might be shorted or has an open in the solenoid
• The wiring in the solenoid circuit is shorted to power or ground, or open circuit from a broken wire or connector
• The solenoid connector can be corroded, which can cause an open circuit.

1. Turbocharger - Did your mechanic just found out that there is some fault in the Turbocharger? Buy top notch Turbocharger from us at economical prices.
2. Engine Turbo Boost - A damaged Engine Turbo Boost can cause a lot of issues. It would be nice if you get it replaced on time.
3. Powertrain Control Module - Everything is fine with the Engine Turbo Boost and still OBD code P0243 flashing? Then there is definitely some fault with the Powertrain Control Module. Get it checked and replace if needed.
4. Solenoid Connector - Solenoid Connector is an important car part which should never be neglected. May be there is some fault in it due to which P0243 code may start flashing.
5. Pressure Control Solenoid - A faulty Pressure Control Solenoid can be troublesome. You can always rely on us as we have best auto parts for our customers.
6. Engine Control Module - If everything is alright with Solenoid Connector, then there is surely some defect in Engine Control Module. Get it replaced before the situation gets worse

Common Symptoms

• The engine turbo boost may not be able to be controlled properly and may under boost the engine
• The engine may lack power during acceleration if the wastegate solenoid is failing to control the correct amount of boost pressure
• There can be an appearance of the check engine light and the code is set in memory

It is very important to fix the fault code P0243. So here are some ways with which you can correct this issue:

• First of all you must replace the wastegate solenoid with an open circuit
• Replace or repair the solenoid wiring connection with corrosion in the pins

However, if you face any issue then we have stocked a wide range of best priced turbo boost, transmission slipping, boost controller and more to help you out in fixing your car.

Here are some steps which you should follow in order to diagnose this fault code:

• The codes should be examined and document the freeze frame data so that you can verify the problem
• The next thing would be to clear the codes to verify whether the concern comes back
• The operation of the wastegate solenoid should be inspected
• Survey the solenoid resistance to see if it is within specifications
• You must check the solenoid connector for loose or corroded pins
• The wiring from the solenoid to the engine control module should be properly examined for shorts or open circuits 

Common Mistakes When Diagnosing The P0243 Code

• You should inspect the wastegate solenoid voltage supply fuse for vehicle battery voltage.
• The electrical connections at the solenoid should be checked for corrosion on pins
