P2716 |
Pressure Control Solenoid "D" Electrical (Shift Solenoid Valve SLT) |
DESCRIPTION
Refer to DTC P0894
.
|
DTC No. |
DTC Detection Condition |
Trouble Area |
|---|---|---|
|
P2716 |
Open or short is detected in shift solenoid valve SLT circuit for 1 second or more while driving (1-trip detection logic). |
|
MONITOR DESCRIPTION
When an open or short in the shift solenoid valve (SLT) circuit is detected, the ECM interprets this as a fault. The ECM will turn on the MIL and store the DTC.

(a) Disconnect the D41 transmission wire connector. |
(b) Measure the resistance according to the value(s) in the table below.
Standard Resistance:
|
Tester Connection |
Condition |
Specified Condition |
|---|---|---|
|
14 (SLT+) - 6 (SLT-) |
20°C (68°F) |
5.0 to 5.6 Ω |
|
14 (SLT+) - Body ground |
Always |
10 kΩ or higher |
|
6 (SLT-) - Body ground |
Always |
10 kΩ or higher |
|
|
2. |
CHECK HARNESS AND CONNECTOR (TRANSMISSION WIRE - ECM) |
|
(a) Disconnect the D56 ECM connector. |
(b) Measure the resistance according to the value(s) in the table below.
Standard Resistance:
|
Tester Connection |
Condition |
Specified Condition |
|---|---|---|
|
D56-9 (SLT+) - D56-8 (SLT-) |
20°C (68°F) |
5.0 to 5.6 Ω |
|
D56-9 (SLT+) - Body ground |
Always |
10 kΩ or higher |
|
D56-8 (SLT-) - Body ground |
Always |
10 kΩ or higher |
|
|
3. |
INSPECT SHIFT SOLENOID VALVE SLT |
|
(a) Remove the shift solenoid valve SLT. |
(b) Measure the resistance according to the value(s) in the table below.
Standard Resistance:
|
Tester Connection |
Condition |
Specified Condition |
|---|---|---|
|
1 - 2 |
20°C (68°F) |
5.0 to 5.6 Ω |
(c) Connect the battery positive (+) lead with a 21 W bulb to terminal 2 and the negative (-) lead to terminal 1 of the solenoid valve connector. Then check that the valve moves and makes an operating noise.
OK:
Valve moves and makes an operating noise.
