Do you think the sensors are not compatable or could their be another problem? I was trying to be cheap and same some money. Please help, i am tired of dumping money in this car...

Being that both codes are for low voltage i would say that you have soldered the factory plugs onto these sensors...Correct???... If so you need to re-do the soldering job so that the resistance is not to high causing the low voltage. To do this, cut and strip both ends of the wires and push them together end to end carefully then solder them. A large solder joint will cause more resistance and a low voltage condition... Keep us posted...
