What is the P0896 fault number? What is the description for the Shift Time Too Long fault code? How can I fix the P0896 fault? What are the causes and symptoms of the P0896 error code?
What is the P0896 fault code? What does it all mean?
Many vehicles come with a separate transmission control module (TCM). Other vehicles incorporate the TCM and the engine control module, ECM into one enclosure. This is the powertrain control module (PCM).
Transmission fluid assists in gear changes, as well as lubricating and cooling moving parts. Transmission fluid is directed through different hydraulic channels by a high-pressure pump within the transmission. A number of electronic pressure control (EPC), solenoids regulate fluid pressure. The PCM is provided with information by transmission pressure sensors. This includes fluid pressure at various points of the transmission. To stop high-pressure fluid flow, electronic shift solenoids are used so that the vehicle can shift into the right gear when instructed.
To determine if the automatic shift is working, the PCM uses voltage signals derived from the transmission output speed and transmission input speed sensors. A P0896 code is triggered if the PCM detects a shift range that is too large based on these signals. This means that the gear shifting is taking too much time and the transmission is stuck in one gear longer than it should. It could be mechanical or electrical.
Note: Depending on the vehicle manufacturer, P0896 might have a different definition. The vehicle’s repair manual, or database, will provide a detailed description of the code.
What is the P0896 Fault Code?
Fault code P0896 can be triggered by the following common causes:
- – Transmission fluid missing or dirty
- – Clogged hydraulic fluid passagelines
- Defective high-pressure pump
- – Gearbox failures that are serious
- – Defective electronic pressure control (EPC) solenoid
- – Defective transmission pressure sensor
- – Defective shift solenoids
- – Connectors and wiring that are damaged, burnedt, shorted/disconnected, or corroded
- – Defective PCM / TCM
What are the Symptoms of P0896 Fault Code
You may experience the following symptoms if your vehicle has the code P0896:
- – Illumination for the check engine light
- – Too high transmission oil pressure
- – Hard shifting and delayed
- – Irregular gear changes
- – Transmission stuck at any gear
- – A hum from the gearbox
- – A strong burning odor emanating from the gearbox
- – Increased fuel consumption
- – Reduced engine performance
How do I fix the P0896 fault code?
There are several repairs that can resolve the P0896 fault code.
- – Topping up and checking the transmission fluid level
- – Replace the transmission fluid that is not in compliance with manufacturer specifications, or of poor quality.
- – Repairing damaged wiring and loose connectors.
- – Fixing transmission fluid leaks
- – Cleansing clogged transmission fluid passagelines
- Repairing a damaged transmission oil pump
- – Replacing a defective electronic pressure control solenoid
- Replacing a damaged transmission pressure sensor
- – Replacing defective shift solenoids
- – Transmission internal mechanical faults can be repaired
- – Complete overhaul of the torque converter and gearbox
- – Replacing the faulty TCM / PCM
How serious is the P0896 Code of Fault?
The P0896 code is an indication that an automatic transmission has a serious problem shifting gears. It is important to correct any conditions that may have contributed to this code being set as soon as possible.
