P0901 OBD-II Diagnostic Powertrain (P) Trouble Code DescriptionP0901 engine trouble code is about Crankshaft Position Sensor A Circuit Low Input.
Reason For P0901 CodeThe reason of P0901 OBD-II Engine Trouble Code is Injector Circuit Malfunction - Cylinders.
P0901 DTCs may also be triggered by faults earlier down the line. For example, a dirty MAF sensor might be causing the car to overcompensate in its fuel-trim adjustments. As a result, oxygen sensors are likely to report fuel mixture problems.
