P171A Fault Code: Understanding The Description And Troubleshooting Tips
The P171A 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 auxiliary fluid system.
The HybridEV Powertrain Control Module 1 is in charge of controlling this solenoid valve by providing the ground path to the control circuit. However, if the control module detects an open circuit on the transmission surge solenoid circuit for 1 second, it will trigger the P171A fault code. This fault code indicates that there is an issue with the control circuit of the transmission fluid pressure accumulator solenoid valve.
It is important to address this problem promptly to ensure proper functioning of the transmission system and avoid potential damage.
