P0345 on Hyundai
Camshaft Position Sensor Circuit Malfunction (Bank 2)
P0345 on Hyundai vehicles indicates camshaft position sensor circuit malfunction (bank 2). Au7o has documented this code across 1 Hyundai model — most commonly on Elantra. P0345 means the engine computer detected a malfunction in the camshaft position sensor circuit on bank 2 (the cylinder bank not containing cylinder number one). The camshaft position sensor tells the computer where the camshaft is in its rotation, which it uses for precise fuel injection and ignition timing and to manage cylinder identification. When the signal is missing, erratic, or out of range, the computer can't reliably track cam position, which may cause hard starting, rough running, stalling, or a no-start. The fault is usually in the sensor, its wiring, or the connector rather than the camshaft itself. Typical repair costs on Hyundai range from $150 to $400, depending on the specific model and root cause.
Common Causes of P0345
- •Failed camshaft position sensor (bank 2)
- •Damaged wiring, connector, or corrosion in the sensor circuit
- •Metal debris or oil contaminating the sensor tip
- •Faulty reluctor/tone wheel on the camshaft
- •Open or short in the sensor signal or power circuit
- •Loose timing chain/belt or VVT issue affecting cam timing
- •Poor ground or low reference voltage to the sensor

- Crankshaft Position Sensor Failure Causing Stalling2011-2017
The crankshaft position sensor fails, causing intermittent stalling, hard starting, and no-start conditions. The problem often worsens when the engine is hot and may not trigger check engine codes initially. Sensor harness corrosion is a common contributing factor.

What does P0345 mean on Hyundai?▼
P0345 stands for "Camshaft Position Sensor Circuit Malfunction (Bank 2)." P0345 means the engine computer detected a malfunction in the camshaft position sensor circuit on bank 2 (the cylinder bank not containing cylinder number one).
