P2761 indicates that the powertrain control module has detected an open circuit in the torque converter clutch pressure control solenoid control circuit. This means the signal that should energize the solenoid is not being completed, so the torque converter cannot apply the clutch as intended. The fault is typically related to the solenoid itself, its wiring/connectors, or a blown fuse, rather than the control module.
The solenoid’s internal winding can break, creating an open circuit that prevents proper operation.
Broken wires, corroded terminals, or loose connectors can interrupt the circuit, causing an open condition.
An overcurrent event can open the fuse or fusible link, cutting power to the solenoid.
The solenoid is often part of the valve body; internal short or open wiring within the valve body can set the code.
Rarely the cause; the PCM is considered only after the solenoid, wiring, and fuses have been verified as good.
No. The fault is usually in the solenoid itself, the wiring, connectors, or a blown fuse. PCM failure is a rare cause and should be considered only after the other components have been checked.
The vehicle may still move, but the torque converter will not lock up, which can lead to higher fluid temperatures, poorer fuel economy, and possible transmission damage. It is advisable to diagnose and repair the issue promptly.
Not directly. P2761 points to an open circuit in the pressure control solenoid circuit. Fixing the wiring, connectors, fuse, or the solenoid itself is the correct approach.
Using a multimeter, measure the solenoid’s resistance; if it reads out‑of‑spec (often infinite or far outside the listed range), the solenoid is likely failed and should be replaced.
