What does code P0335 mean on a Kia and is it safe to drive?
P0335: Crankshaft Position Sensor A Circuit Malfunction. Here's what it means on your Kia, what usually causes it, what repairs typically cost, and how safe it is to keep driving.
What this code means
The PCM is not receiving the expected signal from the crankshaft position sensor (CKP). This sensor tells the ECM the exact position and speed of the crankshaft. Without it, the engine may not start or will stall and run poorly.
Common causes for your Kia
- Failed crankshaft position sensor
- Damaged or corroded sensor wiring/connector
- Tone ring (reluctor wheel) damage or debris
- Failed PCM (rare)
Symptoms
- Engine won't start or stalls unexpectedly
- Check Engine Light on
- Engine cranks but will not fire
- Intermittent stalling at speed
Typical fixes
- Replace crankshaft position sensor
- Inspect and repair wiring harness and connector
- Check tone ring for damage or packed debris
Repair cost range
For a Kia, repairs for P0335 often fall between $100 and $350, depending on the cause and whether you use OEM or aftermarket parts. Labor rates vary by location.
