Q: What does code P2730 mean?

Pressure Control Solenoid 'E' Control Circuit High. P2730 indicates that the transmission control module (TCM) has detected an abnormally high voltage on the control circuit for pressure control solenoid 'E', which is one of several solenoids that regulate hydraulic pressure inside the automatic transmission. The TCM monitors the circuit and sets this code when the voltage exceeds the expected range, typically indicating a short to power, an open circuit, or a faulty solenoid.
