P0344 — Camshaft Position Sensor Circuit Intermittent
Drive with caution — fix soon.
What P0344 means
This code indicates an intermittent fault in the camshaft position sensor circuit, meaning the signal is dropping out or behaving erratically rather than failing completely. It's usually caused by loose connectors, chafed wiring, or a sensor that's beginning to fail. Because the problem comes and goes, technicians often check wiring and connections closely, then replace the sensor if needed.
Common symptoms
- Check engine light is on or flickers
- Occasional stalling or rough running
- Intermittent hard starting
- Random hesitation or surging
- Symptoms that come and go unpredictably
Common causes
- Loose or corroded sensor connector
- Chafed or intermittently shorting wiring
- Failing camshaft position sensor
- Poor ground connection
- Damaged wiring harness near the sensor
Typical repair cost
$110 – $420
Varies by vehicle and root cause.
Frequently asked questions
Can I keep driving with a P0344 code?
Short trips are usually okay, but the intermittent fault can cause sudden stalling, so don't count on it for long or important drives. Get it checked soon.
How much does it cost to fix a P0344 code?
Repairs generally run $110 to $420. A sensor swap is cheaper, but tracking down an intermittent wiring fault can take extra diagnostic time and cost.
Is a P0344 code serious?
It's moderate but unpredictable. The danger is that the fault is intermittent, so the engine may run fine then stall without warning, which is why it shouldn't be ignored.
Why are intermittent codes like P0344 hard to diagnose?
Because the fault isn't always present, a technician may not see it during testing. Loose connectors and chafed wires are common culprits and require careful inspection to find.
