I posted in another thread about my issues with the camshaft magnet and noise when it was energized. I fixed the noise problem but still having an issue.

I am still getting code 24 on Pin 4 ("Left adjustable camshaft timing solenoid (Y49/1) , open or short circuit"). I verified that the magnet is working manually as when I apply 12v to the magnet the engine dies. The issue I fixed was when the cam magnet was plugged in, the engine would rattle very badly when (I assume) the magnet was being energized. When I had the cam magnet unplugged, the noise did not appear, so I assumed the magnet was providing the signal back to the ECU.

After I put the car back together, I drove it a short distance and then re-checked the codes on pin 4. I am still getting the code 24, and also code 22 for an O2 sensor heater, open or short circuit. I cannot clear the codes on this pin with the scanner.

Do I need to drive the car a certain amount of times for code 24 to be cleared? If the code continues I will check voltage on the wires at 3,000 rpm (not under load) to see what it does.

Any other suggestions?
