P0521 leads to a faulty oil pressure switch. Warm oil will catch it faster than cold oil. The P0480, either got a bad fan clutch or the wiring is damaged (hopefully on the clutch end). The plug is on the drivers side of the harm. balancer (be a big square plug), trace the wiring from it up to the fan. Any damage, need to replace the clutch. The P0148 was an intermittent condition, but factors of that code are:
