DTC P0877  : Transmission Fluid Pressure Switch D (5th Clutch) Circuit Low

NOTE:
DTC Description Confirmed DTC Pending DTC Freeze Frame
P0877 Transmission Fluid Pressure Switch D (5th Clutch) Circuit Low      

DTC (A/T)

  1. Problem verification

    -1. Turn the vehicle to the ON mode.

    - 2. Clear the DTC with the HDS.

    - 3. Check the parameter(s) below with the HDS.

    Signal Threshold Current conditions
    Values Unit Values Unit
    5th Pressure Switch ON      

    Do the current condition(s) match the threshold?

    YES 

    The failure is duplicated. Go to step 2.

    NO 

    Intermittent failure, the system is OK at this time. Check for poor connections and loose terminals between transmission fluid pressure switch D (5th clutch) and the PCM. If the freeze data/on-board snapshot of this DTC is recorded, try to reproduce the failure under the same conditions with the freeze data/on-board snapshot.

  2. Determine possible failure area (transmission fluid pressure switch D (5th clutch), others)

    -1. Turn the vehicle to the OFF (LOCK) mode.

    - 2. Disconnect the following connector.

    Transmission fluid pressure switch D (5th clutch) 1P connector

    - 3. Turn the vehicle to the ON mode.

    - 4. Check the parameter(s) below with the HDS.

    Signal Threshold Current conditions
    Values Unit Values Unit
    5th Pressure Switch OFF      

    Do the current condition(s) match the threshold?

    YES 

    Replace transmission fluid pressure switch D (5th clutch) .

    NO 

    Go to step 3.

  3. Shorted wire check (OP5SW line)

    -1. Turn the vehicle to the OFF (LOCK) mode.

    - 2. Jump the SCS line with the HDS.

    - 3. Disconnect the following connector.

    PCM connector B (51P) - Refer to: How to Troubleshoot the A/T System (2014 2015), or How to Troubleshoot the Fuel and Emissions Systems,

    - 4. Check for continuity between test points 1 and 2.

    Test condition Vehicle OFF (LOCK) mode
      Transmission fluid pressure switch D (5th clutch) 1P connector: disconnected
      PCM connector B (51P): disconnected
    Test circuit OP5SW
    Test point 1 PCM connector B (51P) No. 27 (LT BLU)
    Test point 2 Body ground

    Is there continuity?

    YES 

    Repair a short to ground in the OP5SW wire between transmission fluid pressure switch D (5th clutch) and the PCM.

    NO 

    The OP5SW wire is OK. Replace the PCM - Refer to: PCM Removal and Installation (2014 2015), .
