P0483 Cooling Fan Problem Subaru Outback Youtube Video on how to test 2003 subaru outback cooling fans and trouble shoot check engine light code p0483.lisle relay test jumper kits # 56810 sold here:. 98 subaru legacy outback throwing p0483 code. yesterday my check engine light came on, we hooked machine to it, and it threw the code p0483 : coolant fan malfunction. also my air conditioner no longer blows cold. both fans on radiator are working well, radiator does not appear to be clogged (inside radiator or externally with leaves or debris).
P0483 Code Understanding Cooling Fan Rationality Check Malfunctions 10 posts · joined 2009. #3 · dec 17, 2009. miker104 said: so i'm guessing the obdii code was one of these: p0480 cooling fan relay 1 circuit low input (my vote) p0483 cooling fan function problem. turn on the a c and make sure both fans come on. could be fuse (just replace, look in owners manual for where it is). To diagnose the p0483 subaru code, it typically requires 1.0 hour of labor. the specific diagnosis time and labor rates at auto repair shops can vary based on factors such as location, vehicle make and model, and engine type. most auto repair shops commonly charge between $80 and $150 per hour; however, rates in metropolitan areas or at. The p0483 code is defined as “cooling fan rationality check malfunction.”. it is usually triggered by your powertrain control module (pcm) when it detects that the current being drawn by the cooling fan control circuit is either too high or too low. this means that the cooling fan is operating differently from how the pcm intended. The first step to diagnosing a detected p0483 code is to perform a visual inspection of the wiring and connectors between the ecm, the cooling fan, and the pcm. if any appear to be loose, corroded, or faulty, repairing or replacing them should be followed by clearing the code and retesting the system. if the p0483 code returns, then the.
