Please help me with the p0012 code.

This is the v6 4.0 engine. Timing chain and guide replacement operation. Of course, the camshaft position sensor has also been replaced. It's usually fine, but with a high rpm, the p0012 code works intermittently. But the engine has no tremors, no noise, no power restrictions. It's so frustrating. Please help me.

Make sure the oil is clean and at the correct level.

Make the oil is clean and at the correct level.

If you've already done that, what else should you consider?
