What does code P281A mean?

Q: What does code P281A mean?

Pressure Control Solenoid H Intermittent. P281A indicates that the transmission control module (TCM) has detected an intermittent fault in the electrical circuit for pressure control solenoid H, which is used to regulate hydraulic pressure inside the automatic transmission. The TCM monitors the solenoid's current draw and response time, and it sets this code when the signal is erratic rather than completely open or shorted, meaning the fault comes and goes.
