2004 tarus code p0171,p0174, po300

Question

what do codes P0717,P0174, P0300 mean in a 2004 ford tarus mean?

Answer 1

Hi there

the P0300 is for multiple misfires, the P0171 and 174 are for a lean fuel mixture on bank 1 and bank 2. Normally when you get a lean fuel mix code on both banks it's either a problem with the mass air flow sensor or low fuel pressure. Either will also cause the misfire code.
