Is that the only error?

What was the condition when it was report? Does the engine run?

The camshaft sensor wasn't reporting the expected pulse, but it happened only once at very low RPM. And from the low system voltage, it might have been cranking. I assuming that it had been running from the reported temperature. The sensor might be magnetically "contaminated" (rust, residual magnetism, magnetized camshaft) so that it's not reading accurately at low speeds, but it is likely working OK at normal running speeds.

10.61 v is very low voltage, whether the engine is running or not.
Check test your battery/alternator. Recharge it and/or replace it. Then test again.

The voltage is low because it appears while cranking as someone already said. Everything else seems ok. Only had few random deaths of the engine. Code always comes back after clearing

But if there is a code at low rpms, does it not intefier while driving? P.S. you're the only one realised that's the cranking voltage not stable one
