P281B

DTC P281B, sometimes indicated as P281B00 is an OBD diagnostic trouble code indicating a manufacturer-specific fault with the vehicle powertrain (i.e. engine and gearbox). This code identifies an error with the causing pressure control solenoid "h" control circuit/open.

This code is set when the PCM detects an open or short in the H pressure control solenoid circuit.
There are several things that can cause this code to set, including a bad pressure control solenoid, a wiring issue, or a problem with the PCM.
If you have a bad pressure control solenoid, the best thing to do is replace it. If there is a wiring issue, you will need to track down the cause and fix it. If there is a problem with the PCM, you will need to have it checked out by a qualified technician.
