Chevrolet Code P2797 is a diagnostic trouble code (DTC) that indicates a problem with the auxiliary transmission fluid pump performance. Understanding what this code means can help you diagnose the problem and find a solution. Ignition voltage must be between 8-18 volts, and the hybrid powertrain control module monitors the difference between actual and commanded auxiliary transmission fluid pump speed for 4 out of 4.125 seconds. This article will provide a table of causes and solutions that are related to Chevrolet Code P2797.

Chevrolet Code P2797: Faulty Wiring
Chevrolet Code P2797 can indicate that there is a problem with faulty wiring in the vehicle. This is usually caused by loose or corroded wiring or a faulty connection somewhere in the vehicle’s electrical system. To diagnose the problem, a technician will need to use a multimeter to test the voltage at the auxiliary transmission fluid pump. If the voltage is too low, then it is likely that the wiring is faulty and needs to be repaired.
Chevrolet Code P2797: Faulty Transmission Fluid Pump
The transmission fluid pump can also be the cause of the Chevrolet Code P2797. The transmission fluid pump may be at fault if the voltage is within the acceptable range. To diagnose this issue, a technician will need to test the pump’s performance. If the pump is not functioning correctly, it will need to be replaced.
Chevrolet Code P2797: Faulty Hybrid Powertrain Control Module
The hybrid powertrain control module is responsible for monitoring the difference between actual and commanded auxiliary transmission fluid pump speed. If this module is faulty, it can cause Chevrolet Code P2797 to appear. To diagnose this issue, a technician will need to check the module for any problems. If there are any issues, the module must be replaced.
Chevrolet Code P2797: Low Transmission Fluid
The last possible cause of the Chevrolet Code P2797 is low transmission fluid. If the transmission fluid is too low, then it can cause the auxiliary transmission fluid pump not to work correctly. To diagnose this issue, a technician will need to check the fluid level and refill it if necessary.
Conclusion: Solving the Chevrolet Code P2797
The Chevrolet Code P2797 is a diagnostic trouble code that indicates a problem with the auxiliary transmission fluid pump performance. This code has several possible causes, including faulty wiring, a faulty transmission fluid pump, a faulty hybrid powertrain control module, and low transmission fluid. To diagnose and solve the problem, a technician will need to check the wiring, the transmission fluid pump, the hybrid powertrain control module, and the transmission fluid level. Once the cause of the code has been identified, the appropriate solution can be implemented to resolve the Chevrolet Code P2797 code.
