P0345 Code: Nissan Rogue (2021-2024) - Causes, Symptoms & Fixes

No recalls found in NHTSA database (based on the provided data). The official dataset only shows a single owner complaint for P0301 on a 2021 Rogue and does not include any P0345 entries or recalls for 2021-2024 Nissan Rogue. Because there is no P0345-specific data in the provided dataset, this guide uses general Nissan Rogue knowledge for P0345 along with standard OBD-II diagnostic practices.

CODE MEANING AND SEVERITY

• What P0345 means: Camshaft Position Sensor A Circuit Malfunction (Bank 1). This DTC indicates a problem with the circuit that provides the camshaft position sensor’s signal (A), which is used by the engine control module (ECM/PCM) to determine the position of the camshaft relative to the crankshaft.
• Bank 1: The sensor is monitoring the camshaft position on the bank that contains cylinder 1.
• Severity: Moderate to high drivability impact. It can cause rough idling, misfires, reduced power, stalling, or a no-start condition. While not always a direct safety code, it can lead to unsafe situations if the engine stalls while driving. The ECM may disable power or run in a degraded mode to prevent damage, so immediate diagnosis is recommended.

COMMON CAUSES ON NISSAN ROGUE

• Faulty camshaft position sensor (sensor failure or internal fault).
• Damaged, corroded, or loose wiring to the cam sensor (insulation wear, broken conductors, poor ground or 5V reference).
• Damaged or corroded sensor connector or harness connector (pins bent, voltage drop, poor contact).
• Faulty camshaft position sensor ground or 5V reference circuit (ECM/PCM side issue or sensor side issue).
• Timing-related issues (timing chain/belt wear, jumped timing, worn tensioner or guides) causing irregular cam signal, especially if the sensor relies on a stable cam position signal.
• Oil contamination or leaks around the sensor area (oil can contaminate the sensor or its connector and affect readings).
• ECM/PCM fault or software calibration issue (less common but possible).
• Intermittent faults due to vibration or thermal cycling.

SYMPTOMS

• Engine may start poorly or not start at all.
• Rough idle, intermittent misfires, or stalling.
• Loss of power or reduced engine performance.
• MIL (Check Engine Light) illuminated with P0345 stored in the PCM.
• In some cases, you may notice a drop in fuel economy or drivability issues only under certain conditions (hot/cold start, certain RPM ranges, or engine load).

DIAGNOSTIC STEPS

Note: Always start with the data available from your scan tool and work toward mechanical checks. If you’re not comfortable with electrical tests or timing checks, consult a qualified tech.

A. Verify and gather data

• Use an OBD-II scanner to confirm P0345 is current and check for any related codes (P0335, P0336, or other P034x codes), and review freeze frame data (engine RPM, coolant temp, fuel trim, etc.).
• Check for other codes that might indicate broader sensor or ignition problems (P0300-P0304 misfire codes, etc.).
• Confirm no recent work or wiring changes that could affect sensors.

B. Visual inspection

• Inspect the camshaft position sensor and its wiring harness for signs of damage, oil intrusion, corrosion, or loose connectors.
• Inspect the connector pins for bent or pushed-out pins; reseat with a clean connector; apply dielectric grease on reassembly.
• Look for oil leaks around the sensor area; fix any leaks (oil can contaminate the sensor or harness).

C. Electrical checks (high level guidelines)

• With ignition OFF, inspect continuity between sensor ground, sensor supply (5V reference), and signal line using the service manual’s wiring diagram.
• Check PCM 5V reference and ground circuits for shorts or poor connections.
• Use a digital multimeter or oscilloscope to verify sensor power (5V reference) and signal behavior. A healthy CMP signal is a clean, consistent waveform; the voltage on the signal wire should toggle in time with engine rotation when cranking/running.
• If available, monitor the cam signal with an oscilloscope while cranking. Look for a stable, periodic waveform. If the signal is absent, erratic, or constant, the sensor or its circuit is suspect.

D. Sensor resistance and functional tests

• Disconnect the sensor and measure its resistance if the service manual provides a spec. If the resistance is out of spec, replace the sensor.
• Reconnect and test the 5V reference and ground continuity to confirm there’s no open circuit or short to power or ground.
• If you have a scope, compare the CMP waveform to the crankshaft position sensor (CKP) waveform. Large discrepancies can indicate timing or sensor faults.

E. Compare with crankshaft position data

• If P0345 is present but P0335 (CKP) is also present or if CKP is failing, investigate potential timing issues or wheel/reluctor problems that could affect both sensors.
• If CKP and CMP signals appear valid but engine runs poorly, timing chain/chain tensioner wear or a mechanical timing issue may be at fault.

F. Mechanical timing checks (if indicated)

• If the CMP signal appears valid but engine timing is suspect (e.g., suspected jumped timing), perform a timing alignment check per the service manual. This typically involves rotating the crank and checking timing marks with the installation of timing components. Only perform if you have proper tools and know-how; incorrect timing can cause severe engine damage.

G. Rule-out and escalation

• If a replacement sensor does not fix the code and wiring checks are clean, look for PCM/ECM-related issues or software calibration; in rare cases, an updated PCM calibration may be required.
• Consider emission-system readiness and related sensors if driveability improves or worsens with weather/temperature changes.

RELATED CODES

• Camshaft-related: P0340, P0341, P0342, P0343, P0344, P0345, P0346, P0347 (varies by OEM and engine).
• Crankshaft related: P0335 (Crankshaft Position Sensor A Circuit Malfunction), P0336 (Crankshaft Position Sensor A Circuit Range/Performance).
• Misfire and drivability: P0300, P0301-P0308 (cylinder misfire codes).
• If P0335/P0336 appear with P0345, focus first on the crank signal integrity and timing, then cam signal integrity.

REPAIR OPTIONS AND COSTS (2025 PRICES)

Prices vary by region, shop, and whether OEM or aftermarket parts are used. The figures below are rough ranges to help planning and comparison.

DIY VS PROFESSIONAL

• DIY suitability:
  • Reasonable for a typical engine with decent mechanical/electrical aptitude.
  • Pros: Lower cost, quick swap for a known good sensor, hands-on learning.
  • Cons: Difficult if the sensor is hard to reach, if timing component inspection is required, or if wiring harness repair is needed; risk of introducing wiring mistakes or timing errors.
• Professional route:
  • Recommended if: You suspect timing chain issues, PCM faults, or if diagnosis requires scope/advanced diagnostic tools. A technician can verify timing alignment, perform proper waveform analysis, and diagnose PCM-related faults with OEM scan tools.
• Safety: Always disconnect the battery when disconnecting electrical connectors; follow torque specs and reassembly procedures; avoid inhaling fumes and ensure the engine is cool when performing mechanical work near belts and pulleys.

PREVENTION

• Regular electrical inspection: Periodically check cam/crank sensor wiring and connectors for wear, corrosion, and secure fit.
• Keep oil leaks under control: Oil on sensors can cause signal issues; fix leaks promptly.
• Use OEM or recommended replacement parts: Sensor specifications and harness compatibility matter for signal integrity.
• Manage moisture and debris: Ensure sensor housings and connectors are sealed; avoid water intrusion in the engine bay when washing the engine.
• Routine maintenance: Keep air filters, spark plugs, and fuel system clean to minimize drivability issues that could compound sensor-related symptoms.
• Address issues promptly: If symptoms like stalling or misfires appear, diagnose early to avoid further damage.
