Causes
- Failed or degraded camshaft position sensor (CMP)
- Damaged, corroded or loose sensor connector or wiring (open/short/intermittent)
- Incorrect camshaft-to-crankshaft timing (stretched timing chain, jumped tooth, slipped belt)
- Faulty variable valve timing (VVT) solenoid or cam phaser
- Reluctor ring or tone wheel damage or contamination
- Low battery/poor charging system affecting sensor reference voltage
Symptoms
- Malfunction Indicator Lamp (MIL) illuminated
- Rough idle, hesitation or stalling
- Poor acceleration and reduced engine performance
- Intermittent misfires or cylinder specific misfire codes
- Hard starting or extended cranking
- Possible limp-home mode or reduced power depending on ECM strategy
What to check
- Retrieve P0341 and any related codes; record freeze-frame data and live PID values (cam vs crank correlation, RPM, battery voltage)
- Visually inspect cam sensor, connector, and wiring for damage, corrosion, oil or disconnection
- Confirm good battery voltage and charging system while cranking
- Scan tool: monitor camshaft position sensor waveform/angle vs crankshaft position PID
- Check engine oil level and condition (excessive contamination can affect sensors/VVT)
- Inspect timing components for wear or evidence of jumped tooth (if symptoms/history suggest mechanical issue)
Signal parameters
- Hall-effect cam sensors: digital square-wave signal, typically 0–5 V, switching frequency rises with RPM
- Variable reluctor (VR) cam sensors: AC sine waveform; amplitude increases with engine speed (tens to hundreds of millivolts up to a few volts depending on design)
- Expected behavior: consistent pulses at specific cam angle correlating to crank pulses; missing pulses, irregular amplitude, or incorrect phase indicate fault
- Typical failure signatures: intermittent/no signal, noisy or low-amplitude VR output, stuck/high/low DC level for Hall sensor
Diagnostic algorithm
- Read and record all DTCs and freeze-frame data. Note operating conditions when the code set.
- Perform a visual inspection of the CMP sensor, connector and wiring harness for damage, oil contamination, corrosion or loose pins. Repair any obvious faults.
- Using a scan tool, view live camshaft and crankshaft position PIDs and check cam/crank correlation while cranking and at idle. Look for large phase errors or missing cam events.
- Probe the sensor connector: verify reference voltage/power, ground continuity, and signal while cranking. Compare to expected sensor type (Hall vs VR).
- For Hall sensors: check for clean 0–5 V switching with ignition on/cranking. For VR sensors: check AC voltage with an oscilloscope; look for clean sine waves and amplitude change with rpm.
- If wiring checks good but signal is wrong/intermittent, replace the camshaft position sensor and retest.
- If new sensor does not correct the issue, inspect timing components (timing chain/belt, guides, tensioner) and cam phaser/VVT operation for mechanical shift or jump. Repair as needed.
- If mechanical timing and sensor/wiring are OK, consider ECU/PCM faults or software. Confirm with manufacturer bulletins and reflash/update ECM if applicable.
- Clear codes and road-test under similar conditions to verify repair. Re-scan for return of P0341.
Likely causes
- Faulty camshaft position sensor
- Wiring/connector fault at the sensor (corrosion, chafing, pin damage, loose connector)
- Cam timing out of specification (timing chain/belt jumped/stretched)
- Sticking or failed VVT/cam phaser causing incorrect cam angle
Fault status
Status
P0341 — Camshaft Position Sensor 1 Performance Range/Performance. The PCM has detected the camshaft position signal is outside the expected range or the cam/crank correlation is incorrect. Inspect the sensor, wiring, cam timing and VVT components.
Repair difficulty: Medium
Diagnostic time: 1.0-3.0 hours
