DTC P2827: Open in Line Pressure Solenoid Valve A Circuit
- Before you troubleshoot, record all freeze data and any on-board snapshot with the HDS, and review the General Troubleshooting Information (see GENERAL TROUBLESHOOTING INFORMATION ).
- This code is caused by an electrical circuit problem and cannot be caused by a mechanical problem in the transmission.
- Turn the ignition switch to ON (II), or press the engine start/stop button to select the ON mode.
- Clear the DTC with the HDS.
- Start the engine in P, and wait for at least 1 second.
- Check for Pending or Confirmed DTCs with the HDS.
Is DTC P2827 indicated?
YES - Go to step 5.
NO - Intermittent failure, the system is OK at this time. Check for poor connections and loose terminals between line pressure solenoid valve A and the PCM.
- Turn the ignition switch to LOCK (0), or press the engine start/stop button to select the OFF mode.
- Check for a blown No. 13 (15 A) fuse in the driver's under-dash fuse/relay box.
Is the No. 13 (15 A) fuse OK?
YES - Go to step 7.
NO - Repair a short to body ground in the wire between PCM connector terminal B2 and the driver's under-dash fuse/relay box.
- Jump the SCS line with the HDS.
- Disconnect PCM connector B (49P).
- Turn the ignition switch to ON (II), or press the engine start/stop button to select the ON mode.
- Measure the voltage between PCM connector terminal B2 and body ground.

Is there battery voltage?
YES - Go to step 11.
NO - Repair an open in the wire between PCM connector terminal B2 and the driver's under-dash fuse/relay box.
- Turn the ignition switch to LOCK (0), or press the engine start/stop button to select the OFF mode.
- Disconnect the line pressure solenoid valve A connector.
- Connect a jumper wire between line pressure solenoid valve A connector terminal No. 2 and body ground.
- Turn the ignition switch to ON (II), or press the engine start/stop button to select the ON mode.
- Clear the DTC with the HDS.
- With SH-AWD: Raise the vehicle on a lift, make sure it is securely supported, and allow all four wheels to rotate freely.
Without SH-AWD: Block the rear wheels, and raise the front of the vehicle, make sure it is securely supported, and allow the front wheels to rotate freely, or raise the vehicle on a lift.
- Start the engine. With the brake pedal pressed, shift to D, then release the brake pedal.
- Monitoring the APP Sensor (%) with HDS in the A/T Data List, press (2 % opened) and release (0 % opened) the accelerator pedal every 2 seconds.
- Check for Pending or Confirmed DTCs with the HDS.
Is DTC P2826 indicated?
YES - Go to step 20.
NO - Go to step 23.
- Turn the ignition switch to LOCK (0), or press the engine start/stop button to select the OFF mode.
- Remove the jumper wire.
- Check for continuity between line pressure solenoid valve A connector terminal No. 1 and body ground.Fig 3: Checking Continuity Between Line Pressure Solenoid Valve A Connector Terminal No. 1 And Body Ground

Is there continuity?
YES - Faulty line pressure solenoid valve A. Replace the secondary valve body (line pressure solenoid valve A) (see SECONDARY VALVE BODY REPLACEMENT ).
NO - Repair an open in the wire between line pressure solenoid valve A and body ground (G101) (see CONNECTOR TO FUSE/RELAY BOX INDEX ), or repair poor body ground (G101).
- Turn the ignition switch to LOCK (0), or press the engine start/stop button to select the OFF mode.
- Remove the jumper wire.
- Jump the SCS line with the HDS.
- Disconnect PCM connector B (49P).
- Check for continuity between PCM connector terminal B44 and line pressure solenoid valve A connector terminal No. 2.Fig 4: Checking Continuity Between PCM Connector Terminal B44 And Line Pressure Solenoid Valve A Connector Terminal No. 2

Is there continuity?
YES - Replace the PCM (see ECM/PCM REPLACEMENT ).
NO - Repair an open in the wire between PCM connector terminal B44 and line pressure solenoid valve A connector terminal No. 2.
