P0893

2017-10-10

Description:

  • The fault code P0893 indicates that the transmission control module (TCM) has detected multiple gears engaged simultaneously. This code typically points to a mechanical or hydraulic issue within the transmission system, causing incorrect gear engagement.

Possible Symptoms:

  • Malfunction Indicator Lamp (MIL) or Check Engine Light illuminated

  • Transmission slipping or erratic shifting between gears

  • Harsh engagement or disengagement of gears

  • Reduced acceleration or power from the engine

  • Unusual noises coming from the transmission

  • Transmission overheating

  • Poor fuel efficiency

Possible Causes:

  • Incorrect transmission fluid level or condition

  • Electrical or wiring issues in the transmission system

  • Malfunctioning shift solenoids or valves

  • Faulty transmission control module (TCM)

  • Internal transmission mechanical issues, such as worn clutches or bands

  • Hydraulic fluid pressure problems within the transmission

Related Parts:

  • Transmission Shift Sensor: Gear Shift Sensor communicates the position the gear shifted to. Problems lead to difficulty in shifting gears

Possible Solutions:

  • Inspect and test the shift solenoids or valves for proper operation and replace if necessary

  • Test and replace the faulty transmission control module (TCM), if required

  • Perform a thorough inspection of the internal transmission components for any mechanical issues and repair as needed

  • Check and adjust the hydraulic fluid pressure to the correct specifications

  • Ensure the transmission fluid level is correct and the fluid is in good condition, and perform a fluid change if necessary

  • Inspect the electrical connections and wiring in the transmission system for any faults or damage and repair as required
