ERROR DETAILS:
Engine temperature: 72.0 °C
Engine speed: 138 rpm
Fuel quantity: 0.0 mm³/I
Gas pedal position: 0.00 %
Fuel pressure: 287 bar
Boost pressure: 1020 mBar
No help available
The reason for this fault is that ECU did not receive signal from the sensor. The fault is not detected now, but it is stored in memory. Clear fault codes, and observe for future appearance of the same fault. Dashboard warning light was not activated for this fault.
Symptoms of a P250A trouble code may include:
Engine may not start
Low oil pressure gauge reading
Service engine soon light illuminated
Check engine light illuminated
ERROR DETAILS:
Engine temperature: -1.5 °C
Engine speed: 184 rpm
Fuel quantity: 0.0 mm³/I
Gas pedal position: 0.00 %
Fuel pressure: 357 bar
Boost pressure: 1008 mBar
Anomaly on the revolutions signal. Check the following:
– Harness
– Continuity and resistive value of the sensor
– Check the insulation of the grounding wires
– (by an oscilloscope) signal emitted by the sensor, the engine being started on or in starting attempt
NOTE: The fault may also be shown in case of engine not running or if the operator did not attempt the cranking.
The reason for this fault is that ECU has received invalid signal from the sensor. The fault is not detected now, but it is stored in memory. Clear fault codes, and observe for future appearance of the same fault. Dashboard warning light was activated for this fault.
P0335 Crankshaft Position Sensor A Circuit Malfunction
A P0335 “check engine light” code could be caused by:
Damaged CKP sensor connector
Damaged reluctor ring (missing teeth or not turning due to sheared-off keyway)
Sensor output open
Sensor output shorted to ground
Sensor output shorted to voltage
Failed crank sensor
Broken timing belt
Failed PCM
The reason for this fault is that ECU has received invalid signal from the sensor. The fault is present now. Take appropriate action to fix this sensor fault. Dashboard warning light was not activated for this fault.
Potential causes of a P0520 code include:
Faulty engine oil pressure sensor
Excessive resistance in the oil pressure sensor circuit
Short in the circuit to/from the oil pressure sensor and/or PCM and/or ground
Faulty PCM (less likely)
