P1298 on Acura
Injector Driver Module (IDM) Failure / Electrical Load Detector Fault (manufacturer-specific)
P1298 on Acura vehicles indicates injector driver module (idm) failure / electrical load detector fault (manufacturer-specific). Au7o has documented this code across 1 Acura model — most commonly on Integra. 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. Typical repair costs on Acura range from $150 to $3,500, depending on the specific model and root cause.
Common Causes of P1298
- •Failed Injector Driver Module (IDM) internal fault (Ford diesel)
- •Wiring or connector faults between IDM and PCM/injectors
- •Poor power or ground to the injector driver module
- •Electrical Load Detector (ELD) circuit fault (some applications)
- •Corroded or damaged harness connectors
- •Moisture intrusion into the module/connectors
- •Faulty PCM/ECM
P1298 on Acura by Model
Acura Integra(1 issue)
- 4-speed automatic: shift solenoid failure causes D4 light flash, missed shifts, and limp mode1994-1999
The Honda BAXA/MAXA 4-speed automatic in the Integra is notoriously sensitive to fluid condition and shift-solenoid contamination. Solenoid A/B failure causes flashing D4 light, harsh or missed 2-3/3-4 shifts, loss of power in D4/D3, and sometimes speedometer drop-out. Integra often faces delayed or missed shifts and manual downshifting difficulties in automatic transmissions. Shifting problems in the 1998 Integra's automatic transmission can stem from a clogged transmission filter or screen restricting fluid flow. This causes poor hydraulic pressure, leading to missed 4th gear shifts and failure to downshift. While driving, the D4 suddenly lost almost all power, wouldn't shift, and the speedometer stopped working. Codes returned were Automatic Transaxle FI A circuit failure and ELD error.
