P171B Fault Code: Understanding The Description And Troubleshooting Tips
The P171B 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 HybridEV Powertrain Control Module 1 is in charge of controlling the solenoid valve by providing the ground path to the control circuit.
However, in this case, there is a short to ground on the transmission surge solenoid circuit for 1 second, resulting in low voltage in the control circuit. This fault code indicates that there is an issue with the transmission fluid pressure accumulator solenoid valve control circuit, which can lead to problems with the transmission’s ability to supply fluid line pressure after an Autostop event. It is important to address this issue promptly to ensure proper transmission function and avoid further damage.
