P0345 on Honda
Camshaft Position Sensor Circuit Malfunction (Bank 2)
P0345 on Honda vehicles indicates camshaft position sensor circuit malfunction (bank 2). Au7o has documented this code across 1 Honda model — most commonly on Passport. 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 Honda range from $40 to $300, 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
P0345 on Honda by Model
Honda Passport(1 issue)
- Idle Stop (Auto Start-Stop) Stalling and Failure to Restart2019-2023
Honda Passport owners report the Idle Stop (automatic engine start-stop) feature causing dangerous stalling issues. When the engine auto-stops at red lights or in traffic, it fails to restart when the brake is released, leaving the vehicle stranded in traffic. The "Collision Mitigation System" warning light often appears during these incidents. The Idle Stop system is overly aggressive and doesn't account for battery health, A/C load, or hot weather conditions. Unlike some competitors, Honda doesn't have a shift interlock, so the vehicle can roll if stalled on a hill. Many owners permanently disable Idle Stop to avoid this issue.
