P0300-MULTIPLE CYLINDER MISFIRE
When Monitored: Any time the engine is running, and the Target Learning Coefficient
has been successfully updated.
Set Condition: When more than a 1.8% misfire rate is measured during two trips. Above
3000 RPM 1 trip less than 3000 RPM 2 trip.
P0315-NO CRANK SENSOR LEARNED
When Monitored: Under closed throttle decel and A/C off. ECT above 75°C (167°F).

the reference. One Trip Fault.
P0335-CRANKSHAFT POSITION SENSOR CIRCUIT
When Monitored: Engine cranking.
Set Condition: No CKP signal is present during engine cranking, and at least 8 camshaft

I'm not concerned with the P0300 code as this won't prevent it from starting.
Can you tell me which engine is in this vehicle?
