Error Code P0897: What It Means & What To Do?

<<See All OBD Codes

A P0897 code gets stored when the Engine Control Module (ECM) discovers that transmission fluid levels are drastically poorer than manufacturer proposals and might pose hard to the transmission.

The self-activated transmission uses transmission fluid that is set underneath high pressure to make shifts that separate gear ratios. If ever the ECM transmits a message, in which the present gear ratio is not the exact calculation that it describes, then this will store a code.

Just to advise, setting the parameters of the code will differ as of make and model. Do it is best to detect your vehicle manual to find out the proper recommendations for your car. 

OBD-II Transmission Code that might not change correctly is the means of a Transmission Fluid Degenerated.

The Transmission Fluid has started to get polluted and has to be changed right away.

What causes this problem with the Transmission Fluid Deteriorated?

• Level of transmission fluid is poorer than manufacturer details
• Transmission fluid is filthy or polluted
• Corroded or failed shift solenoids
• Hydraulics are blocked throughout the transmission fluid channel ways
• Corroded or failed transmission control module
• Transmission defect
• Corroded or failed ECM (uncommon)

1. Engine Control Module - The ECM could falter if there is damage or deterioration within the internal wiring inside the injector wiring harness or the sensor wiring harness, which leads to a short in the ECM, or damage can enter the ECM through the wiring harness. This could also happen when having exposure to the different elements in the vehicle’s environment.
2. Transmission Fluid - Transmission fluid set at low levels or leaking transmission fluid are the most common issues involving transmission. Transmission fluid set at low levels typically occurs when there is a leaking transmission system. The transmission or driveshaft obtains seals that may be failing and leaking fluid. Periodically, transmission gasket seals may need replacement, so the leaks inside the transmission can be sealed. Other times, transmission fluid may be contaminated by coolant within the radiator. Usually, we refer this to cross-contamination that tends to happen on occasion. Symptoms that involve poor fluid levels or fluid leaks can also apply as slipping gear or slow shifting. In cases that fluid has been aged or contaminated, the fluid has to be changed or else the transmission is entirely washed out and filled up again.
3. Shift Solenoid - A transmission solenoid that failed or opened circuit and is detected in any area inside the electrical system might lead the transmission to access a Fail Safe or Limp mode as a way to delay the transmission from interior damage that may happen due to a failed solenoid or open circuit. If you are surmising that the electrical connection might be dealing with a problem, or is displaying any signs of damage, then make sure an experienced mechanic has it surveyed.
4. Transmission Control Module - Problems with your transmission control module can lead to being unable to change gears properly, which can lead to accidents and injury. On top of that, driving with a failed transmission control module can lead to constant damage on the wiring within your transmission. When these symptoms become very evident to you, it is important to have your car surveyed by a professional mechanic as soon as possible.
5. TCM Wiring - Water can start to corrode the inside of the connector between the engine and transmission wiring harness. The engine may start to crank, only without starting, stalling, and/or the transmission may not change correctly. To fix a TCM wiring harness, simply replace the positive fuse able relay and battery in your car. A more effective idea is to replace the engine harness when the battery acid has damaged the wiring harness connection.
6. TCM Connector - The transmission pin connector plug imposes most of the transmission slip or delayed engagement issues on the speed transmission of your car. It leaks transmission fluid to the pin connector and depraves the car from communicating with the valve body. The issue points to the transmission connector plug leaking oil at the rubber O rings. Therefore, in advance to doing anything else to your car, you should make sure to replace this plug and add transmission oils to get rid of this constant problem.
7. Fluid Pressure Pump - The car will not start or suddenly stalls and will not restart. A fuel pump that failed may prevent a car from starting up or might make it stall. Check for the engine light to come on. At other moments, a fuel pump will gradually begin to fail, which means the fuel pressure and volume gradually begins to dissolve. The fuel that may be deprived will lead to an engine performing with not enough fuel in correspondence to the quantity of air, which results in the check engine light turning on. With a fuel pump that is failing, you may notice a vibrating sound coming from the fuel tank area, sourced from the rear of the car. If the fuel pump is producing the noise, it’s usually imminent for a pump to fail and you have to replace the fuel pump right away. Even during the drive, the pump may still lead to an engine that is overheated, which is the same for a catalytic converter. When a fuel pump is failing, it can leave you stranded on the road, but a car will not start on several missions before finally driving again. However, if the fuel pump issue involves a gasoline or vapor leakage, it is not safe to continue driving, and should instantly be checked by an experienced mechanic.
8. Electronic Pressure Regulator - If the car’s fuel pressure regulator fails or has problems it will interrupt the car’s fuel pressure. This will throw off the engine’s air fuel ratio and tune that can have a drastic impact on the car’s performance. A defective fuel pressure regulator might lead the car to face misfires, a power loss and acceleration, also a plunge in fuel competence. These symptoms may also happen by a large range of other problems; so having the car correctly diagnosed is highly advised. If the fuel pressure regulator diaphragm, especially if any of the seals fail, then fuel leaks take place. A defective regulator only leaks gasoline, a possible safety caution, but also leads to performance problems. A fuel leak will normally create a visible fuel odor, and might also lead to engine performance problems. Another symptom is black smoke coming from the exhaust of a possible issue with the car’s fuel pressure regulator. If the fuel pressure regulator leaks or falters inside, it may lead the car to release black smoke from the tailpipe. A defective fuel pressure regulator can lead the car in running far too richly, separate from decreasing miles per gallon (mpg) and performance can lead the car to create black smoke coming from the tailpipe. A wide range of other problems can produce black smoke as well, so having the car correctly diagnosed is highly advised. As some fuel pressure regulators are constructed into the fuel pump assembly, most fuel pressure regulators are placed into the fuel rail and can be independently serviced and repaired at for the rest of the process. If you surmise that your car might be facing a problem with the fuel pressure regulator, then have a certified mechanic inspect the car, such as Parts Avatar, to find out if the instrument should be replaced.
9. Pressure Gauge Adapter - The oil pressure gauge located inside your car will give you a good glimpse into the situation of the engine’s oil levels. If the Low Oil Light turns on, but you have detected the oil in the engine and its level is very good, then you might blame a defective oil pressure sensor. When this sensor turns bad, it will begin sending irregular readings. After the readings drop out of definition, this sets off a warning light. The faster you can replace this sensor, the less you will deal with the strain of noticing the oil levels in your car. On other occasions, the Low Oil Light will flash on and off when the oil pressure sensor is putting out. This can alarm the driver, since the damage that is lower than regular oil levels can cause such issues to an engine. To check continually can be so timely and straining, as it’s mandatory to conserve the correct oil levels. Instead, you should get the oil pressure sensor replaced right away by an experienced mechanic.

A mechanic might use multiple steps to diagnose a P0897 error code, which does include:

• Using an OBD-II scanner to detect for a stored P0897 error code
• Detect transmission fluid levels and make a comparison with manufacturer definitions for the car’s make and model
• Detect the transmission fluid quality
• If the fluid is burning, detect for pollution and remains inside the transmission pan
• Remains in the transmission pan is an indicator that a sum calculation of transmission reconstruction, fluid washout, and a new torque converter are definitely needed
• Do a viewable examination of the system for any wiring that is shorted or burned
• Detect if needing to replace the interior transmission harness
• Detect for any transmission fluid leakage
• Detect for transmission fluid pump pressure by reading a manual pressure gauge
• Detect shift solenoid source and ground indicators for any signs of corrosion
• If opened voltage or ground circuits are sourced, detect for consistency and refusal to comply

Common Mistakes When Diagnosing the P0897 Code

There are moments when shift solenoids are improperly sought out to be the asserted cause of the P0897 when the issue is justified as a transmission defect. It is put forward to completely diagnose any transmission-associated issues before taking out any shift solenoids.
