What is the fault code P0893? What is the description for the Multiple Gear Engaged fault code? How do I fix the P0893 fault code What are the causes and symptoms of the P0893 error code?
What is the P0893 fault code? What does it signify?
The code P0893 means that the powertrain controller module (PCM), has detected multiple gears being engaged simultaneously. This could be caused by a variety of electrical or mechanical faults, and can severely affect your vehicle’s driveability.
To calculate the automatic transmission shift strategy, the PCM relies on input signals from multiple transmission and engine sensors. The electronic shift solenoids cut off high-pressure fluid flow to allow the automatic transmission to shift gears. It is impossible to achieve the desired gear ratio if more than one solenoid activates at the same moment.
Note: Depending on which vehicle manufacturer you are using, the definition of P0893 fault code may vary. The vehicle’s repair manual, or repair database, will provide a detailed description of the code.
What causes the P0893 Fault code?
Fault code P0893 is most commonly triggered by the following:
- – Defective shift solenoid(s)
- – Connectors and/or wiring that are damaged, burnedt, disconnected, corroded, or shorted
- – Severe mechanical failures within the gearbox
- – Defective PCM / TCM
What are the symptoms for the P0893 fault code?
These symptoms may be present if you own a vehicle that has the code “P0893”:
- – Illumination for the check engine light
- – Irregular gear changes
- – Hard shifting and delayed
- Gearbox slip
- – The gearbox is overheated
- – Gearbox Friction Noise
- – Transmission oil that has strong odors from brake lining
- – Increased fuel use
- – Lower engine performance
How do I fix the P0893 fault code?
These are some of the possible repairs that can resolve the P0893 fault codes:
- – Replacing a defective shift solenoid (s)
- – Repair of damaged wiring, loose connectors and open or short circuit issues
- – Repair of internal mechanical faults in transmissions
- – Replacing the defective PCM/TCM
How serious is the P0893 Fault code?
P0893 codes can be caused by mechanical failures of several components, such as faulty shift solenoids. The clutch pads may become fused in more severe cases due to excessive friction. You could be paying a lot of money for transmission repairs.
