I have a message after the car had been running for around 15 minutes saying: oil pressure low stop the engine). I have replaced the PCM in the car because I got code p062 ECU error. I got PCM refurbished and reprogram with vin number. So here I got check engine light and code P0315 crank shaft position sensor not learned. What is going on with this car? Are the computer needs to be programmed being installed on the car or is the computer is bad?

Can you please double check the code #, code p062 is missing a digit. Also, there is no crankshaft relearn for this car, here are the instructions and they mention it. Check out the images (below). Let me know the other code please.

Yep, that is the problem then, the PCM is not programmed correctly. I would try it again. Here is the correct way to replace the PCM in case you need it. Check out the images (below). Please let us know what happens.
