P171C Fault Code: Understanding The Description And Troubleshooting Steps
The P171C fault code refers to a problem with the transmission fluid pressure accumulator solenoid valve control circuit. This solenoid valve is responsible for controlling the charging and discharge of the accumulator pressure in the automatic transmission.
The power to the solenoid comes from an ignition circuit, and the control of the solenoid is managed by the HybridEV Powertrain Control Module 1. In this case, the fault code indicates that there is a high voltage issue in the control circuit of the solenoid valve.
This means that the voltage in the circuit is higher than it should be, which can lead to improper functioning of the solenoid and affect the transmission fluid pressure.
It is important to address this issue promptly to prevent further damage to the transmission system.
