I was wondering if someone can help me with a little problem i am having, i have 97' mazda 626 2.5L, throwing code p0443, evaporation emission control system purge control valve. took the two sensors off the back of the intake part numbers are k5t44094 and k544093, ohmed both and both are like 33 ohms cold, i dont have the car with me at the moment so a cold test is all i can do. anyways i am having a hard time trying to find these sensors at pull a part, i keep finding ones that have different part numbers, i am assuming they have to match i was wondering if someone could confirm that for me, do they have to be exact numbers as what came off the car, i have checked probes, 626's, millenia's and mx-6. thanks for any info
