When it comes to Mitsubishi code P0243, it is important to know that it stands for Turbocharger Wastegate Solenoid Circuit Malfunction. This code is triggered when the engine is running with the system voltage between 10-16 volts and the PCM has detected that the Wastegate solenoid coil surge voltage is too low. There are several potential causes for this code, and it is important to understand the underlying causes and solutions to this problem.
Causes and Solutions for Mitsubishi Code P0243
| Cause | Solution |
|---|---|
| Turbocharger wastegate solenoid circuit is open or shorted to ground | Inspect and repair the wiring harness and connectors of the turbocharger wastegate solenoid circuit. |
| Turbocharger wastegate solenoid failed | Replace turbocharger wastegate solenoid |
| PCM has failed | Replace the PCM and reprogram it |
| Insufficient engine vacuum | Check for engine vacuum leaks, repair or replace as necessary |
Faulty Wiring Harness
Mitsubishi code P0243 is caused when the turbocharger wastegate solenoid circuit is open or shorted to ground. If this is the case, the wiring harness and connectors of the turbocharger wastegate solenoid circuit must be inspected and repaired. This is the most common cause of this code and it is important to troubleshoot any wiring issues before proceeding to the other potential causes.
Failed Turbocharger Wastegate Solenoid
Another potential cause for Mitsubishi code P0243 is a failed turbocharger wastegate solenoid. If this is the case, the solenoid must be replaced. This is a relatively straightforward job and can be done by a competent technician.
Failed PCM
The PCM (Powertrain Control Module) can also be a cause of Mitsubishi code P0243. If the PCM has failed, it must be replaced and reprogrammed. This can be a time consuming and expensive job and should only be done by an experienced technician.
Insufficient Engine Vacuum
Finally, Mitsubishi code P0243 can be caused by insufficient engine vacuum. If this is the case, the engine must be checked for vacuum leaks. If there are any leaks, they must be repaired or replaced as necessary.
Conclusion
Mitsubishi code P0243 is triggered when the engine is running with the system voltage between 10-16 volts and the PCM has detected that the Wastegate solenoid coil surge voltage is too low. There are several potential causes for this code, including faulty wiring harness, failed turbocharger wastegate solenoid, failed PCM, and insufficient engine vacuum. It is important to understand the underlying causes and solutions to this Mitsubishi Code P0243 problem in order to properly address it.
