What this code means
Camshaft Position Sensor Circuit Intermittent.
P0344 is a generic code: it means the same thing on every make. P0344 belongs to family P03xx — Ignition and misfire. Its page explains how to read a code and groups all its codes by part.
Type of fault
The signal drops out or jumps from time to time. This is typical of a poor contact: a loose or corroded connector, or a chafed wire that touches intermittently, often triggered by vibration or heat. The fault may disappear and come back; checking the wiring with the engine running is often revealing.
Camshaft position sensor
This sensor reads a target on the camshaft and tells the control unit where each cylinder is in its cycle. Combined with the crankshaft sensor, it lets the control unit fire each injector and spark at the right moment and, on engines with variable valve timing, measure the actual cam position.
What you notice
Starting may take longer, or the engine may not start at all on some models. Hesitation, jerking or a sudden stall can occur, and the control unit may switch to a degraded mode with reduced power.
How to check it
The sensor is usually held by a single screw on the cylinder head or timing cover. Check its connector, look for oil inside it (a leaking seal can wick oil into the wiring) and inspect the tip for metal debris. If the timing belt or chain has recently been replaced, a wrongly aligned timing can also trigger these codes.
Watch it live in Klaro
With an OBD2 adapter plugged in, these live readings show the part at work, when your car reports them:
- Engine RPM
- Timing advance
What to do
Have it checked promptly. A misfire sends unburnt fuel into the exhaust and destroys the catalytic converter within a few dozen kilometres. If the light is flashing, stop driving.
Clearing a code switches the light off but repairs nothing: if the fault remains, the code comes back. Clearing a fault code yourself →
