Current signal.
The other code is P0016 which means the camshaft position sensor and the crankshaft position sensor are out of synch. The timing belt is what keeps the 2 sensors in synchronization so I looked at the timing marks. Align the crank pulley mark with the pin on the timing cover and the camshaft gear marks should be aligned. They are out of synch 1/2 tooth and your timing belt teeth are in very bad condition. The belt will soon lose teeth and jump. This is an interference engine, which means if the belt jumps you will most likely severely damage the engine.
Timing belt replacement is supposed to be 60,000 miles. I can't really tell if that has ever been replaced but it definitely needs it now. So we have the sensor that should be replaced and the belt that needs replaced. Pretty much what they told you at Young's. There are some other things.
Your air intake hose is rotten and falling apart so the air going into the engine is not going through the air filter. Needs a new hose and clean that dirt from the throttle.
Your upper radiator hose is rotten and swollen, easy to replace while doing the other work.
Those things. Timing belt, cam sensor, air intake, radiator hose, clean throttle... if that is all it needs, about $900. I can't tell about pulleys or water pump until the lower cover and timing belt are removed but if need those as well you're going to be up to around $1100. I won't have this done before monday or tuesday, depending on any complications like that.
Also, as if that wasn't enough you should know about a couple other things as well. Your front struts are leaking fluid so need replaced and your a/c compressor is leaking refrigerant. Those are things could be done later for sure but expensive things that it needs as well so you can better get an overview.
