i have had a couple check engine codes pop up recently. a p0115 ( coolant temp sensor malfunction) a p0325 (engine knock sensor malfunction) and a p1105 ( a dsm specific fuel pressure solenoid malfunction). Basically my question is are these codes completely unrelated? i think the knock sensor and the fuel pressure soleniod could possible be related but i dont think that the coolant temp sensor would be related to any of the above. i have read that the coolant temp code could be caused by a bad pcm but the car is actually running fine at the moment. I just ran the codes havent dug into anything as far as freyed wires or looked at any connections as of yet i was going to start at the fuel pressure solenoid issue first as i think that could be causing the knock issue as well. thanks for the info. the car is a 98 gst spyder.
