P2EBD Crankcase Temperature Sensor Circuit High

P2EBD is set when the crankcase temperature signal rises above its highest valid voltage. With the usual pull-up arrangement this happens when the current path through the sensor is interrupted, for example by an unplugged or oil-soaked connector, a broken wire or an open element, or when the signal touches the 5 V reference or battery voltage. For an NTC thermistor, whose resistance grows as it cools, the module then sees an impossibly cold crankcase; a PTC element would read as overheated instead. No manufacturer documents P2EBD, so limits and debounce times are not public. Under (e)(15.2.1) of 13 CCR 1968.2 the high fault has to be stored separately from the low fault P2EBE and from the rationality fault P2EBC.

Likely causes

Connector unplugged, oil-soaked or with spread terminals
Signal or ground wire broken
Sensor element open circuit
Signal shorted to 5 V reference or battery voltage

Symptoms

  • Check engine lamp on
  • Crankcase temperature fixed at an extreme value
  • Engine runs normally
