Volvo All Engines (2013 Emissions) Fault Code: P24FC00 PID: EMS Particulate Matter Sensor Heater Control Circuit Driver Current/Temperature Too High

Circuit description
The aftertreatment particulate sensor measures the amount of particulates in the exhaust system. The aftertreatment particulate sensor is connected to the DL7 data link. The Diagnostic Trouble Code (DTC) indicates a particulate sensor monitoring failure. For example a short circuit, open circuit or voltage out of range

Conditions for diagnostic trouble code (DTC)
Particulate sensor heater, Temperature out of range

Probable cause
1) Internal fault in component

Volvo All Engines (2013 Emissions) Fault Code: P24FF00 PID: ACM Reductant Temperature Too High

Circuit description
Aftertreatment Control Module (ACM) monitors DEF tank temperature and uses it to control the Aftertreatment DEF Tank Heater valve to keep the DEF from freezing.
This temperature monitoring is also used to avoid stopped DEF dosing due to high DEF tank temperatures. If the DEF temperature is too high, reverse flow will be activated, if the temperature stays high for a short duration, a DTC is set.

Conditions for diagnostic trouble code (DTC)
Temperature above 70??C (158??F)

Observable symptoms
No aftertreatment diesel exhaust fluid (DEF) dosage

Probable cause
1) Extreme driving conditions (High ambient temperature)
2) DEF Tank too close to hot object
3) DEF Tank heating valve stuck open
4) DEF Tank Heating Valve installed backwards
5) Temperature Sensor, Aftertreatment diesel exhaust fluid (DEF) tank

Conditions for diagnostic trouble code (DTC):
1) Voltage below normal or shorted low

Diagnostic operating conditions
1) Ignition key in ON position

Observable symptoms
1) The oil level cannot be measured

Probable cause
1) Connector

3) Engine oil level (EOL) and temperature sensor
4) Engine Control Module

Volvo All Engines (2013 Emissions) Fault Code: P250F00 PID: EMS Engine Oil Level Circuit Too Low

The Engine Oil Temperature/Level Sensor contains two resistors: One for engine oil temperature and one for engine oil level.
Diagnostic trouble code (DTC) Placeholder will be present only when a problem with the engine oil level (EOL) circuit has failed. Please reference Placeholder for engine oil temperature (EOT) sensor circuit diagnostics.
The resistance of the engine oil level portion of the sensor changes inversely to the level of the engine oil. The Engine Control Module (ECM) monitors the voltage drop across the sensor and uses this signal to warn that the engine oil level is not within programmed limits. In some cases the engine will derate.
The engine oil level is monitored when the key is on, before the starter is engaged. If low engine oil is detected, either from parking on an incline, or actual low oil, the code will remain active until the next key cycle. It is important that the vehicle is level during key on, or the low engine oil level code may remain.

Conditions for diagnostic trouble code (DTC):
1) Engine oil level (EOL) is below warning level

Probable cause
1) Vehicle not parked on a level surface
2) Low oil level
3) Connector
4) Engine oil level (EOL) and temperature sensor

Detailed information
1) Engine may have to be off up to 20 minutes depending on temperature before checking the oil level.

Volvo All Engines (2013 Emissions) Fault Code: P253901 PID: EMS Low Pressure Fuel System Sensor Circuit

The Boost Air Pressure Sensor is used to monitor the pressure of the air in the intake system after the turbocharger. The sensor consists of a pressure sensitive diaphragm/amplifier sensor. Air pressure causes the sensors diaphragm to deflect and produce an electrical signal proportional to the pressure. The diaphragm deflection signal is amplified in the sensor.
The sensor signals are used to calculation fuel injection and is monitored by the Engine Control Module (ECM).
The engine control module (ECM) will set a diagnostic trouble code (DTC) and derate the engine to avoid engine damage if the sensor signal is not within predetermined limits, or the signal is not rational.

Conditions for diagnostic trouble code (DTC):
1) General Electrical Failure
