Common Next Steps
Turn the code into the next check.
Check coil boots, carbon tracking, and whether the miss follows a swap.
Inspect gap, fouling, wear, oil, coolant, and plug-well condition.
Move to injector balance, pulse, or leak-down checks if the misfire stays.
Use compression or leak-down testing when spark and fuel checks do not move the fault.

Code Overview
P0341 is an engine position sensor, circuit, or signal integrity fault. Confirm signal quality and mechanical timing context before replacing sensors.
Common Causes
- Crankshaft or camshaft position sensor signal dropout, heat failure, or contamination
- Connector corrosion, loose pins, damaged shielding, or harness rub-through
- Reluctor wheel damage, metal debris, excessive air gap, or sensor mounting issue
- Timing chain stretch, slipped timing, phaser issue, or cam/crank correlation fault
- Low battery voltage or starter draw reducing cranking signal quality
- PCM input fault only after waveform and circuit checks support it
Symptoms
- Cranks but will not start
- Intermittent stall
- Extended crank
- Tachometer dropout
- Misfire-like rough running
Diagnostic Steps
- Check cranking RPM and whether RPM drops out during no-start or stall events
- Inspect CKP/CMP connectors, harness routing, oil intrusion, heat damage, and sensor mounting
- Scope crank and cam signals for missing pulses, noise, weak amplitude, or correlation errors
- Check power, ground, reference, and signal continuity before replacing sensors
- Inspect reluctor condition, timing marks, chain stretch, or phaser faults if correlation codes are present
- Verify repair with hot restart, extended road test, and stable RPM/cam data
