P0345 on Nissan
Camshaft Position Sensor Circuit Malfunction (Bank 2)
P0345 on Nissan vehicles indicates camshaft position sensor circuit malfunction (bank 2). Au7o has documented this code across 1 Nissan model — most commonly on Altima. 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 Nissan range from $1,200 to $2,500, 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

- VQ35DE V6 Timing Chain Rattle from Worn Secondary Chain Guides and Tensioners2002-2018
On the 3.5L VQ35DE V6 the plastic secondary timing chain guides/tensioner shoes become brittle and break, and the secondary (cam) chain tensioners lose tension. This produces a loud rattle or whine from the front of the engine, most pronounced for the first few seconds of a cold start. When a guide breaks, the chain runs slack and can contact the tensioner piston (the 'death rattle'), risking valve-timing skip and internal damage if ignored. Owners across multiple Altima forums document this as one of the defining VQ35DE problems, and there is a Nissan TSB covering secondary-chain replacement.

What does P0345 mean on Nissan?▼
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). 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. On Nissan specifically, this code is documented across 1 model.
What causes P0345 on Nissan vehicles?▼
Common causes on Nissan: 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.
