DTC P2720
DTC P2720 : A/T Clutch Pressure Control Solenoid Valve D Low Input
- This code is caused by an electrical circuit problem and cannot be caused by a mechanical problem in the transmission.
- If DTC P2720 is stored in the PCM, the transmission does not shift to 2nd or 5th gear because of the fail-safe function.
| DTC Description | Confirmed DTC | Pending DTC | Freeze Frame |

| P2720 A/T Clutch Pressure Control Solenoid Valve D Low Input |
DTC (A/T)
- Problem verification
-1. Turn the vehicle to the ON mode.
- 2. Clear the DTC with the HDS.
- 3. Check for Pending or Confirmed DTCs with the HDS.
DTC Description Confirmed DTC Pending DTC Freeze Frame P2720 A/T Clutch Pressure Control Solenoid Valve D Low Input Is DTC P2720 indicated?
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 A/T clutch pressure control solenoid valve D 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.
- Fuse check
-1. Turn the vehicle to the OFF (LOCK) mode.
- 2. Check the following fuse.
Fuse No. C5 (7.5 A) Location Under-hood fuse/relay box Is the fuse OK?
YES
The fuse is OK. Go to step 3.
NO
Replace the No. C5 (7.5 A) fuse, and recheck. If the fuse blows again, repair a short to ground on the No. C5 (7.5 A) fuse circuit, and recheck.
- Open wire check (IG1 VBSOL (7.5 A) line)
-1. Jump the SCS line with the HDS.
- 2. Disconnect the following connector.
- 3. Turn the vehicle to the ON mode.
- 4. Measure the voltage between test points 1 and 2.
Test condition Vehicle ON mode PCM connector A (51P): disconnected Test circuit IG1 VBSOL (7.5 A) Test point 1 PCM connector A (51P) No. 1 (PUR) Test point 2 Body ground Is there battery voltage?
YES
The IG1 VBSOL (7.5 A) wire is OK. Go to step 4.
NO
A)repair an open in the IG1 VBSOL (7.5 A) wire between the PCM and the No. C5 (7.5 A) fuse in the under-hood fuse/relay box.
- Determine possible failure area (short in LSD line, others)
-1. Turn the vehicle to the OFF (LOCK) mode.
- 2. Reconnect PCM connector A (51P).
- 3. Jump the SCS line with the HDS.
- 4. Disconnect the following connector.
- 5. Check for continuity between test points 1 and 2.
Test condition Vehicle OFF (LOCK) mode PCM connector B (51P): disconnected Test circuit LSD Test point 1 PCM connector B (51P) No. 9 (TAN) Test point 2 Body ground Is there continuity?
YES
Go to step 5.
NO
Go to step 6.
- Shorted wire check (LSD line)
-1. Disconnect the following connector.
A/T clutch pressure control solenoid valve D 2P connector - 2. Check for continuity between test points 1 and 2.
Test condition Vehicle OFF (LOCK) mode A/T clutch pressure control solenoid valve D 2P connector: disconnected PCM connector B (51P): disconnected Test circuit LSD Test point 1 A/T clutch pressure control solenoid valve D 2P connector No. 2 (TAN) Test point 2 Body ground Is there continuity?
YES
Repair a short to ground in the LSD wire between A/T clutch pressure control solenoid valve D and the PCM.
NO
The LSD wire is OK. Faulty A/T clutch pressure control solenoid valve D. Replace the secondary valve body (A/T clutch pressure control solenoid valve D) .
- Open wire check (LSD line)
-1. Disconnect the following connector.
A/T clutch pressure control solenoid valve D 2P connector - 2. Check for continuity between test points 1 and 2.
Test condition Vehicle OFF (LOCK) mode A/T clutch pressure control solenoid valve D 2P connector: disconnected PCM connector B (51P): disconnected Test circuit LSD Test point 1 A/T clutch pressure control solenoid valve D 2P connector No. 2 (TAN) Test point 2 PCM connector B (51P) No. 9 (TAN) Is there continuity?
YES
The LSD wire is OK. Go to step 7.
NO
Repair an open in the LSD wire between A/T clutch pressure control solenoid valve D and the PCM.
- Open wire check (LSD PG line)
-1. Check for continuity between test points 1 and 2.
Test condition Vehicle OFF (LOCK) mode A/T clutch pressure control solenoid valve D 2P connector: disconnected PCM connector B (51P): disconnected Test circuit LSD PG Test point 1 A/T clutch pressure control solenoid valve D 2P connector No. 1 (BLK) Test point 2 Body ground Is there continuity?
YES
The LSD PG wire is OK. Go to step 8.
NO
Repair an open in the LSD PG wire between A/T clutch pressure control solenoid valve D and ground (G101) or repair poor ground (G101).
- A/T clutch pressure control solenoid valve D check
-1. Measure the resistance between test points 1 and 2.
Test condition Vehicle OFF (LOCK) mode A/T clutch pressure control solenoid valve D 2P connector: disconnected PCM connector B (51P): disconnected Test circuit LSD, LSD PG Test point 1 A/T clutch pressure control solenoid valve D 2P connector No. 1 Test point 2 A/T clutch pressure control solenoid valve D 2P connector No. 2 Is there 4.7-5.9 -Ω
YES
A/T clutch pressure control solenoid valve D is OK. Replace the PCM - Refer to: PCM Removal and Installation (2014 2015) .
NO
Faulty A/T clutch pressure control solenoid valve D. Replace the secondary valve body (A/T clutch pressure control solenoid valve D) .
