Pressure control solenoid D is fed a carefully regulated current by the transmission or engine computer, which also measures what actually flows. P2716 sets when that current or the circuit voltage is impossible for a healthy coil and wiring – typically an open circuit, a short to ground or a short between the two wires. On Toyota's U660E and U760E this is the SLT line-pressure solenoid, and the fail-safe is blunt: without SLT control, line pressure goes to maximum, so every engagement and shift becomes very harsh, and many transmissions also restrict gears. Unlike P2714, this is an electrical fault that a multimeter can pin down, so the diagnosis follows the wiring from the computer to the solenoid rather than starting with the fluid.
Can I keep driving? You can usually reach a shop, but expect hard shifts and possibly a limp mode with limited gears. Avoid hard acceleration and towing, since maximum line pressure hammers clutches and mounts.
How to read P2716
- P Powertrain
- 2 Generic (SAE)
- 7 Transmission
- 16 Specific fault
Symptoms
- Check engine light and often a transmission warning at the same moment
- Very harsh engagements into Drive and Reverse
- Hard, jolting upshifts in every gear
- Transmission stuck in one gear or limited gears (limp mode)
- Fault appears after hitting a bump or once the transmission is hot
- Other solenoid circuit codes stored if a shared connector is at fault
Possible causes
Ranked by how often each cause is behind this code (editorial estimate).
- Transmission case connector with fluid wicking, corroded or loose pins
- Solenoid D coil open or shorted internally
- Internal harness inside the pan damaged or chafed
- External harness chafed near the exhaust, subframe or a mount
- Computer connector or output driver fault
- Poor ground or supply to the transmission computer
Diagnosis step by step
Note when the fault sets
Check the freeze frame for fluid temperature, speed and gear. A code that appears only when hot or after bumps points to a wire or connector that loses contact as parts expand or move, rather than a dead coil.
Tools: OBD-II scanner
Inspect the transmission connector
Unplug the connector on the transmission case and look for transmission fluid inside, green corrosion or pushed-back pins. Fluid in the harness side means it wicked through a leaking connector seal, which must be replaced along with cleaning the pins.
Tools: Flashlight, Screwdriver
Measure the solenoid through the case connector
Measure resistance between the two pins for solenoid D at the transmission connector. On Toyota linear solenoids such as SLT, expect roughly 5 to 5.6 ohms at about 68 °F; each pin to transmission case should show no continuity at all.
Tools: Multimeter
Go inside if the reading is wrong
If the reading is open, near zero or shorted to the case, drop the pan and measure directly at the solenoid. A good solenoid with a bad reading at the case connector means the internal harness is damaged; a bad solenoid reading confirms the coil.
Tools: Multimeter, Towels & shallow pan, Torque wrench
Check the wiring back to the computer
If the transmission side measures correctly, check each wire from the transmission connector to the computer for continuity and for shorts to ground or to each other. Inspect the computer connector pins and the module's power and ground supply.
Tools: Multimeter
Repair, reset and verify
After the repair, clear codes, reset transmission adaptives and road-test through all gears. Shift quality should return to normal immediately once the solenoid is controlled again.

Notes by brand
Toyota
On U660E and U760E automatics in the Camry, RAV4, Highlander and Sienna, P2716 refers to the SLT solenoid. Because the transmission defaults to full line pressure, owners usually notice very harsh shifts right away; the solenoid can be measured at the case connector before any parts are removed.

Emissions / smog test impact
Will fail
The check engine light is on with P2716 stored, so the car fails the OBD part of a smog or emissions test. After the repair, drive until the readiness monitors show complete.
Frequently asked questions
How is P2716 different from P2714?
P2716 is electrical: the computer sees an open or short in solenoid D's circuit. P2714 means the circuit is fine, but the solenoid or its valve isn't performing. P2716 is found with a multimeter; P2714 usually needs pressure testing and fluid inspection.
Why are the shifts so harsh?
On many transmissions solenoid D controls line pressure. When the computer loses control of it, the hydraulics default to maximum pressure so the clutches can't slip – safe for the transmission in the short term, but every shift slams.
Can I replace the solenoid myself?
If you're comfortable dropping the transmission pan and refilling with the correct fluid to the exact level, it's doable on many units. The refill and level check are what trip up most DIY attempts.
Does a fluid leak at the connector matter?
Yes. Fluid wicking into the connector corrodes the pins and can travel up the harness toward the computer. Replace the connector seal and clean the pins as part of the repair.
