I was reading over the manual for the car and it was saying that the ECM might be a defective if codes like 41 are present. Is there any way to test the ECM to check and see if it is working (note: the ECm has been replaced by previous owner).
Also, I started to check my fuses to see if that had any part in this problem and I notice that when I pull a certain fuse out the gas gauge falls to nearly empty (before removing I notice Low Fuel light is on) and the FUel light goes off. Could the problem be a wiring?
Thank you for taking the time to read this post
code 41 in my manual is telling me the cam sensor curcuit
this and the crankshaft sensor send info to the ignition module then to the ecm. the ecm decide's timing and sends info back to the ignition module to fire the coils
the wires from the cam sensor to the ignition module should be checked then if good then check the wires from ignition module to ecm if they are good then the module or the ecm may have internal problems
