P0339 on Toyota
Crankshaft Position Sensor A Circuit Intermittent
P0339 on Toyota vehicles indicates crankshaft position sensor a circuit intermittent. Au7o has documented this code across 1 Toyota model — most commonly on Corolla. The crankshaft position (CKP) sensor 'A' signal is intermittent, dropping in and out. The controller intermittently loses the crank reference, typically causing random stalls or no-restart events that are hard to reproduce. Often a loose connector, marginal sensor, or chafed wire. Typical repair costs on Toyota range from $120 to $350, depending on the specific model and root cause.
Common Causes of P0339
- •Intermittent wiring or loose/corroded connector
- •Heat-sensitive or marginal CKP sensor
- •Variable air gap from a loose sensor
- •Damaged/chafed harness
- •Reluctor ring runout

- Crankshaft Position Sensor Failure Causing Stalling, Hard Start and P03352000-2010
The crankshaft position sensor (near the bellhousing/starter, PN 90919-05030 on 2ZR-FE cars) degrades on high-mileage Corollas, sending an erratic or lost signal to the ECU. This causes intermittent stalling, hard or no-start conditions and sets P0335 'Crankshaft Position Sensor A Circuit Malfunction' (or P0336/P0339). Symptoms are often heat-related and intermittent, making it a frequently searched no-start cause.

What does P0339 mean on Toyota?▼
P0339 stands for "Crankshaft Position Sensor A Circuit Intermittent." The crankshaft position (CKP) sensor 'A' signal is intermittent, dropping in and out. The controller intermittently loses the crank reference, typically causing random stalls or no-restart events that are hard to reproduce. Often a loose connector, marginal sensor, or chafed wire. On Toyota specifically, this code is documented across 1 model.
