That code isn't even listed in the ODB II code index. P0301 to P0312 are all misfire codes for specific cylinders on teh motor but unless you ahve a 15 cylinder engine that isn't going to be an accurate indication. The codes jump from P0213 to P0320. Reset the vehicle computer by removing the Negative battery cable for 1 minute and reconnect then wait for the check engine light to reappear and have the code read at Auto Zone or Advance Auto, they will use a code reader to read the code for free.

    Hi hope this helps.
    P0313 misfire detected with low fuel
    P0314 single cylinder misfire (cylinder not specified)
    P0315 crankshaft position system - variation not learned
    P0316 misfire detected during startup - first 1000 revolutions
    P0317 Rough road hardware not present
    P0318 rough road sensor signal A - Circuit malfunction
    P0319 rough road sensor signal B - Circuit malfunction
    P0320 crankshaft position (CKP) sensor/engine speed (RPM) sensor - circuit malfunction
    Hope this fills in the gap

  • P0315 Crankshaft Position System Variation Not Learned
  • Have you had any drivable problems.
  • You may have a crankshaft sensor beginning to fail.
  • If you dont have any drivable problems have it rest and see if it comes back on.
  • Hope this helps FixYa

    Po315 code in my 2005 saturn ion 2,2engine car rins fine i erese it code keep coming back

    Of course it comes back. You didn't repair anything. Erasing the diagnostic data doesn't fix the problem.
    It means that the Crankshaft sensor variation has not been learned. You will need a professional, bidirectional scan tool to perform that relearn.

    What does this mean? u have a electric air pump that pumps fresh air into the exhaust system during cold start, this reduces exhaust emissions, that pump is defective, replace it.
