P2EBECrankcase Temperature Sensor Circuit Low
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- How the car detects it
- P2EBE reports a crankcase temperature signal below the lowest voltage the circuit can produce when intact. In practice a short is behind it: either the signal lead has rubbed through to ground on the engine block, or the insulation inside the sensor has given way, for instance after oil has crept into the housing. If the sensor is an NTC thermistor, a low voltage stands for great heat, so the module would believe the crankcase is overheating; a PTC element would appear frozen. No manufacturer publishes this code. The reading matters because systems such as Ford's crankcase heating in US9228557 use it to judge whether warm air arrives. CARB's 13 CCR 1968.2 keeps the low fault apart from P2EBD (section (e)(15.2.1)). The engine itself usually runs on unchanged.
- What you may notice
- Check engine lamp on
- Live data shows an implausible crankcase temperature
- Crankcase heating or ventilation checks suspended
- Likely causes
- LikelySignal wire chafed through to ground on the engine
- PossibleSensor shorted internally after oil ingress
- RareFaulty input stage in the engine control module
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
- Repair
- Easy · Often possible to do yourself.Typical cost: €40 – €250
