Q: Check Engine Light is ON sometimes and then it turns OFF and then turn back ON again

asked by on

The Check Engine Light of my car turn ON and suddenly when I am driving it turns OFF and it turns ON again. I have an OBDII scanner that I used to scan my ECM and the faulty code read as P0337 which is Crankshaft Position Sensor 'A' Circuit Low Input.

My car has 129400 miles.

Based on the information you provided. Your crankshaft position sensor is the most likely cause of your concern. You may also see a p0339 code which is also a crankshaft position sensor code. I recommend having a certified professional inspect the Check Engine Light code in person before moving forward with a repair since it could be a closely related part causing the problem.
