The car's hydraulic pump, which helps control the transmission, is not turning off when it should. It's like a toy with a motor that won't stop running.
The hydraulic pump in the transmission is supposed to turn on and off as needed. This code means it's not turning off properly.
The P094B code indicates that the transmission control module (TCM) has detected that the hydraulic pump is continuously running when it should be turned off. This can lead to increased wear and potential overheating of the transmission system.
• Transmission overheating
• Decreased fuel efficiency
• Unusual noises from the transmission
• Faulty hydraulic pump
• Malfunctioning transmission control module
• Electrical issues such as a short circuit
Hydraulic Pump: A device that moves fluid within the transmission to help control gear shifts.
Transmission Control Module (TCM): An electronic component that manages the operation of the transmission.
• Check for any additional trouble codes.
• Inspect the hydraulic pump for signs of damage or wear.
• Test the electrical connections to the pump for continuity.
• Replace the faulty hydraulic pump.
• Repair or replace damaged wiring or connectors.
• Reprogram or replace the transmission control module if necessary.
