P1298 is an OBD-II diagnostic trouble code meaning “Injector Driver Module (IDM) Failure / Electrical Load Detector Fault (manufacturer-specific).” P1298 is a manufacturer-specific powertrain code with maker-dependent meaning. On Ford diesel (Power Stroke) applications it indicates an Injector Driver Module (IDM) failure, meaning the module that fires the injectors has an internal fault. On some other Ford/Honda references it relates to an Electrical Load Detector (ELD) or related circuit. The diesel IDM variant can cause hard starting, misfire, rough running, or a no-start, so it should be diagnosed promptly. This code is most commonly reported on 1994-1999 Acura Integra (LS, GS, RS, Special Edition), with repair costs ranging from $150 to $3,500.
