DTC P051E, sometimes indicated as P051E00 is an OBD diagnostic trouble code indicating a generic fault with the vehicle powertrain (i.e. engine and gearbox). This code identifies an error with the engine idling stability causing crankcase pressure sensor circuit intermittent/erratic.

There are a few things that could cause this code. One possibility is a bad crankcase pressure sensor. Another possibility is a bad connection or wiring issue at the sensor. A third possibility is a problem with the ECM. If the code comes back, you may want to have a technician investigate the cause.
