DTC No. | Detection Item | DTC Detection Condition | Trouble Area | MIL | Memory | Note |
---|---|---|---|---|---|---|
P271314 | Pressure Control Solenoid "D" Circuit Short to Ground or Open | While the engine is running, a short to ground or open is detected in the solenoid (SLT) valve circuit for 1 second (1-trip detection logic). |
| Comes on | DTC stored | SAE Code: P2720 |
MONITOR DESCRIPTION
When an open or short to ground in the solenoid (SLT) valve circuit is detected, the ECM will determine that there is a malfunction, illuminate the MIL and store this DTC.

PROCEDURE
1. | CHECK HARNESS AND CONNECTOR (TRANSMISSION WIRE (SOLENOID (SLT) VALVE) - ECM) |
(a) Disconnect the C32 ECM connector.
(b) Measure the resistance according to the value(s) in the table below.
Standard Resistance:
Tester Connection | Condition | Specified Condition |
---|---|---|
C32-67 (SLT+) - C32-37 (SLT-) | 20°C (68°F) | 5.0 to 5.6 Ω |
C32-67 (SLT+) or C32-37 (SLT-) - Body ground and other terminals | Always | 10 kΩ or higher |
NG | GO TO STEP 3 |
|
2. | REPLACE ECM |
(a) Replace the ECM.

3. | CHECK HARNESS AND CONNECTOR (TRANSMISSION WIRE - ECM) |
(a) Disconnect the C30 transmission wire connector.
(b) Disconnect the C32 ECM connector.
(c) Measure the resistance according to the value(s) in the table below.
Standard Resistance:
Tester Connection | Condition | Specified Condition |
---|---|---|
C30-24 (SLT+) - C32-67 (SLT+) | Always | Below 1 Ω |
C30-23 (SLT-) - C32-37 (SLT-) | Always | Below 1 Ω |
C30-24 (SLT+) or C32-67 (SLT+) - Body ground and other terminals | Always | 10 kΩ or higher |
C30-23 (SLT-) or C32-37 (SLT-) - Body ground and other terminals | Always | 10 kΩ or higher |
NG | REPAIR OR REPLACE HARNESS OR CONNECTOR (TRANSMISSION WIRE - ECM) |
|
4. | INSPECT SOLENOID (SLT) VALVE |
(a) Remove the solenoid (SLT) valve. Click here |
|
(b) Measure the resistance according to the value(s) in the table below.
Standard Resistance:
Tester Connection | Condition | Specified Condition |
---|---|---|
Solenoid (SLT) valve connector terminal 1 - terminal 2 | 20°C (68°F) | 5.0 to 5.6 Ω |
(c) Connect a positive (+) lead from the battery with a 21 W bulb to terminal 1 and a negative (-) lead to terminal 2 of the solenoid valve connector. Check that the valve moves and makes an operating sound.
OK:
Valve moves and makes an operating sound.
OK | REPAIR OR REPLACE TRANSMISSION WIRE |
NG | REPLACE SOLENOID (SLT) VALVE |
