- Check for damage or clogging of filter
- Check for connection of harness wiring, connector and terminal
- Check for faulty TCM
- Check for faulty valve body assembly
Do you have a Mitsubishi car and is the P1778 code showing up on your screen? This code is related to a malfunction of the stepper motor in the Continuously Variable Transmission (CVT). It is important to understand what this code means and how to fix it. The code is triggered when the difference between the target value of the primary pulley speed and the actual measurement value is greater than the standard value, and the difference between the target pulley ratio and the actual pulley ratio is 0.3 or greater. This status must continue for 5 seconds in order for the code to be triggered.
Causes and Solutions of the Mitsubishi P1778 Code
| Cause | Solution |
|---|---|
| Malfunction of TCM | Check for connection of harness wiring, connector and terminal |
| Malfunction of valve body assembly (Faulty stepper motor) | Check for faulty TCM |
| Clogged filter | Check for damage or clogging of filter |
| Faulty valve body assembly | Check for faulty valve body assembly |
Are you looking for a way to troubleshoot the Mitsubishi P1778 code? This code is related to the Continuously Variable Transmission (CVT) and is triggered when the difference between the target value of the primary pulley speed and the actual measurement value is greater than the standard value, and the difference between the target pulley ratio and the actual pulley ratio is 0.3 or greater. Knowing the potential causes and solutions of this code can help you repair the issue quickly and efficiently. The causes may include a malfunction of the TCM, clogged filter, or faulty valve body assembly, while the solutions may include checking connections, TCM, and filter. Keep reading to find out more about the causes and solutions of the Mitsubishi P1778 code.
Malfunction of TCM
If the TCM (Transmission Control Module) is malfunctioning, it can cause the Mitsubishi P1778 code to be triggered. The solution in this case is to check the connection of the harness wiring, connector, and terminal. Make sure that all components are securely connected and that there are no loose or damaged wires.
Malfunction of Valve Body Assembly (Faulty Stepper Motor)
If the valve body assembly is malfunctioning, it can also cause the Mitsubishi P1778 code to be triggered. The solution in this case is to check the faulty TCM. Make sure that the TCM is working properly and that there are no issues with it.
Clogged Filter
A clogged filter can also cause the Mitsubishi P1778 code to be triggered. The solution in this case is to check for damage or clogging of the filter. Make sure that the filter is clean and that there are no blockages.
Faulty Valve Body Assembly
If the valve body assembly is faulty, it can also cause the Mitsubishi P1778 code to be triggered. The solution in this case is to check for a faulty valve body assembly. Make sure that the valve body assembly is working properly and that there are no issues with it.
Conclusion
In conclusion, the Mitsubishi P1778 code is related to a malfunction of the stepper motor in the Continuously Variable Transmission (CVT). The code is triggered when the difference between the target value of the primary pulley speed and the actual measurement value is greater than the standard value, and the difference between the target pulley ratio and the actual pulley ratio is 0.3 or greater. The causes may include a malfunction of the TCM, clogged filter, or faulty valve body assembly, while the solutions may include checking connections, TCM, and filter. If you have a Mitsubishi car and the P1778 code is showing up on your screen, it is important to understand the potential causes and solutions of this code in order to fix it quickly and efficiently. Mitsubishi P1778 Code should be troubleshooted with care and precision.
