    I have a 07 c13 accert with a 9-3 code. Looked it up and it appears to be an IVA code. I just want to know if not fixing this right away will hurt the engine at all? Will the engine run hotter? Will fuel mileage really suffer? Will this code derate my power at all? My boss isnt the fastest to get things into a shop and i still have 5000 bushels of corn to haul so i just wanna know if i will hurt the motor or if it will only increase emmisions. Thanks and good day

    Flash code 93 is problem with #3 or #4 IVA. Could be current high, low or not responding. The ECM uses a default torque map when active and will cause reduction in power.
