Error Code P0897 is defined as Transmission Fluid Deterioration. This is a generic trouble code, meaning it applies to all cars equipped with the OBD-II system, especially those made since 1996 up to present. This code appears in cars with transmission fluid temperature sensor. Specifications on the definition, troubleshooting, and repairs, of course, vary from one make and model to another.
Error Code P0897 is set when the PCM determines a lower transmission fluid level than the specified recommendation, which could be harmful to the transmission.
The automatic transmission uses transmission fluid that is continuously in high pressure to switch between gear ratios. If the PCM determines that the current gear ratio is not specified for your 2009 Saturn Vue , the code will be stored.
The code-setting parameters vary from one make and model of your 2009 Saturn Vue . Thus, it’s important to check the service manual for the right specifications for your 2009 Saturn Vue .

In some cases, your 2009 Saturn Vue may not show any symptoms at all.
First, check the stored code using an OBD-II scanner.
Next, inspect the transmission fluid levels and make sure it’s within the manufacturer’s parameters for your 2009 Saturn Vue make and model. Check the fluid’s quality to see if it’s burnt or contaminated and if there’s debris in the transmission pan. Debris in the pan suggests it requires a total transmission rebuild, flushing of fluids, and a need for a new torque converter.
Next, check for burnt or shorted wirings.
Then check the internal transmission harness. Replace if necessary.
Next, check for any leaks in the transmission.
Check the transmission fluid pump pressure using the manual pressure gauge.
Check for signs of damage in the shift solenoid reference and ground signals.
If ground circuits and reference voltage are open, then check for resistance and continuity.
Make sure you clear all the codes, test-drive your 2009 Saturn Vue and rescan to see if the code reappears before any repairs.
This code is usually misdiagnosed when the actual cause is transmission failure. Thus, it is best to fully diagnose any codes related to the transmission before making any replacements, especially the shift solenoids.
