DTC P0877
DTC P0877 : Transmission Fluid Pressure Switch D (5th Clutch) Circuit Low
- Before you troubleshoot, review the General Troubleshooting Information - Refer to: How to Troubleshoot the Fuel and Emissions Systems, or How to Troubleshoot the A/T System (2014 2015), .
- This code is caused by an electrical circuit problem and cannot be caused by a mechanical problem in the transmission.
- If DTC P0877 is stored in the PCM, the transmission does not shift to any gear other than 2nd or 5th gear because of the fail-safe function.

| P0877 Transmission Fluid Pressure Switch D (5th Clutch) Circuit Low |
DTC (A/T)
- 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.
- 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.
- 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), .
