Bruce Nunnally Posted February 16, 2010 Report Share Posted February 16, 2010 Normally diagnostic trouble codes (DTCs) are formed of a letter, such a P, with a 4-digit number, like this: P2575 The first digit of the 4-digit number is 0 for generic, or a 1 or a 2 for Manufacturer specific. The sequences you gave ARS 257521119093 IPC 25742938 2246 are possibly P2575 and P2574 with extra information added? I assume these came from a scan tool? or from the 2003 on-board diagnostics? Not sure what the ARS system is. IPC relates to the instrument panel cluster I did find one reference http://www.myazcar.com/pdf/2008_DLC_diag_codes.pdf that suggests: P2574 Direct Ozone Reduction Catalyst Deterioration SensorCircuit Low P2575 Direct Ozone Reduction Catalyst Deterioration Sensor Circuit High which would tie these two together to the same problem.
