Volvo All Engines (2013 Emissions) Fault Code: U300257 PID: EMS Vehicle Identification Number

Volvo All Engines (2013 Emissions) Fault Code: U300257 PID: EMS Vehicle Identification Number

The Idle Validation Switch is open at the idle position and transmits no voltage to the (VECU) Vehicle Electronic Control Unit. At approximately 1-13% pedal position the Idle Validation Switch closes and completes the circuit to the (VECU) Vehicle Electronic Control Unit.
The (VECU) Vehicle Electronic Control Unit then sends a voltage signal to the Engine Control Module (ECM) indicating accelerator pedal position. If both communication links (J1939, J1587) are faulty the pedal demand functionality enters limp-home. During limp-home the (IVS) Idle Validation Switch is used for ramping requested torque.

Conditions for diagnostic trouble code (DTC):
1) Incorrect vehicle identification number (VIN) from vehicle electronic control unit (ECU)

Observable symptoms
1) Engine does not start

Probable cause
1) The electronic control unit (ECU) has a software fault or the wrong software version

Volvo All Engines (2010 Emissions) Fault Code: SPN 100 FMI 1 PID: 100 Engine Oil Pressure

The Engine Oil Pressure Sensor is used to detect engine lubrication system failures. The sensor consists of a pressure sensitive diaphragm and amplifier. Engine oil pressure causes the sensor’s diaphragm to deflect and produce an electrical signal proportional to the pressure. The diaphragm deflection signal is amplified in the sensor. The sensor’s signal 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.

Observable symptoms
1) Low Power
2) Reduced engine output and engine switch-off if the vehicle speed falls below 3 km/h (2 mph) when engine protection is chosen in the data set

Probable cause
1) Low engine oil level (EOL)
2) Contaminated oil, slow flowing or too thin
3) Reduction valve
4) Worn oil pump
5) Engine oil pressure (EOP) sensor
6) Oil leakage

Volvo All Engines (2010 Emissions) Fault Code: SPN 100 FMI 17 PID: 100 Engine Oil Pressure – Least Severe Level

The Engine Oil Pressure Sensor is used to detect engine lubrication system failures. The sensor consists of a pressure sensitive diaphragm and amplifier. Engine oil pressure causes the sensor’s diaphragm to deflect and produce an electrical signal proportional to the pressure. The diaphragm deflection signal is amplified in the sensor. The sensor’s signal 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) The voltage at pin EB:11 is less than 0.3?V

Observable symptoms
1) The engine oil pressure (EOP) gauge shows 0 when the engine is running
2) Loss of power

Probable cause
1) Open circuit, Signal wire
2) Open circuit, Supply wire
3) Short circuit to ground, Signal wire
4) Engine oil pressure (EOP) sensor
