Question

2003 Kia Sorento LX 3.5L with engine codes P0335 and P0727

2003 Kia Sorento stalled two times turning left and accelerating to 30 mph. Both times it restarted after a few minutes. Check engine light comes on: Cleared it between stalls and the same codes show up. Codes that show up on the code reader are P0335 Crankshaft Position Sensor and P0727 Engine Speed input no signal. Wondering if this is common and what the problem usually is, Crankshaft position sensor, faulty wiring, or something else?

Answer 1

P0335 Crankshaft position sensor circuit malfunction

P0727 input speed sensor signal malfunction

Just do the crankshaft position sensor, without the crankshaft position sensor the ECM doesn't know the vehicle is running so it doesn't give fuel, So the input doesn't see the vehicle moving or running so it doesn't give shift commands, this is a typical scenario. The location is in the timing belt area,
