Code P1345 Mazda Description
When the engine is running, the high and low parts of the teeth cause the gap with the sensor to change. The changing gap causes the magnetic field near the sensor to change. The change in the magnetic field cause the voltage from the sensor to change.
When the crankshaft position sensor (POS) system becomes inoperative, the camshaft position sensor provides various controls of engine parts instead, utilizing timing of cylinder identification signals.

Driving with this code is not recommended as it can lead to poor engine performance, increased fuel consumption, and potential damage to engine components.
How do I fix the P1345 code on a Mazda?
Fixes may include replacing the camshaft position sensor, repairing damaged wiring or connectors, adjusting the timing, or reprogramming the ECM.
How do I diagnose the P1345 error code on a Mazda?
Start by inspecting the camshaft position sensor, checking for damaged wiring or loose connections, verifying timing chain/belt alignment, and testing the ECM functionality.
Does the P1345 code mean my camshaft position sensor is bad?
Not necessarily. While a faulty sensor is a common cause, the issue could also stem from wiring problems, timing issues, or an ECM malfunction.
How much does it cost to fix the P1345 code on a Mazda?
Repair costs vary depending on the issue but may range from $100–$300 for a sensor replacement to higher costs for timing-related repairs.
Will replacing the camshaft position sensor clear the P1345 code?

MAZDA MPV 2000. I CHANGE THE OIL PUMP, LATER THE CAMSHAFT POSITION SENSOR. STILL GIVING ME THE CODE P1345. COULD IT BE THAT THE CAMSHAFT IS REALLY OUT OF TIME. ALSO BEFORE HAVING ENGINE PROBLEMS I DID AN ENGINE OIL FLUSH. LATER START WITH OVER HEATING PROBLEMS. OIL PRESURE LIGHT ON THEN OFF WHEN ACCELERATING. OVER HEATING AND THE ENGINE STOP TURNING ON BECAUSE OF OVERHEATING. WIRING ITS OK. SHOULD I DO ANOTHER OIL FLUSH (BAD JOKE). MAYBE.

Other than the Camshaft Position Sensor, I have not seen any other components setting the P1345 code. Unfortunately, it's very possible that the timing was not properly set during the Oil Pump installation.
