Hello,

I could use some guidance. I recently replaced the water pump and timing belt on my 03 SE Neon. At first it didnt want to start. Later, it finally did and I drove it a mile and it seemed to run fine. Now, it starts first try.

However, I have a flashing engine light. These are my codes:






Ive read about a crank sensor needing to be reset with a fancy scanner in some situations.

My question is if that is a normal procedure to do when changing a timing belt?

Is it possible this P0315 code saying crank variation not learned is because the sensor needs to be reset?

Or is it more likely that I installed the belt with the timing off?

Any input is greatly appreciated.
