What does code P281E mean?

Q: What does code P281E mean?

Pressure Control Solenoid H Control Circuit High. P281E indicates that the transmission control module (TCM) has detected an abnormally high voltage on the control circuit for pressure control solenoid H, which is one of several solenoids that regulate hydraulic pressure inside the automatic transmission. The circuit is considered high when the voltage exceeds the expected range for the commanded current, often because the solenoid coil is open, the ground path is broken, or the control wire is shorted to voltage.
