P1124 Diagnostic Trouble Code (13 interpretations)

The control module detected a fault associated with the Ignition system diagnostic monitor, cylinder 2 - duration too short circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by BMW.

The control module detected a fault associated with the Throttle Position Sensor Out of Self - Test Range circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by Ford.

Ford documents P1124:00 (no sub type information) for its 2024-2025 gasoline-engine OBD monitor strategy as tp out of self-test range. This three-byte interpretation is application-specific and identifies the detected monitor condition rather than a confirmed failed component.

The control module detected a fault associated with the Fuel System Lean - Idle circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by Hyundai.

The control module detected a fault associated with the Long Term Fuel Trim Adaptive Air System High circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by Kia.

The control module detected that the Throttle position (TP) voltage stayed above the expected range. This is the manufacturer-specific definition used by Land Rover.

The control module detected a fault associated with the Throttle position (TP) sensor - out of self - test range circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by Mazda.

The control module detected a fault associated with the Differential Pressure Sensor Intake Manifold Adaptation circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by MINI.

The control module detected improper operation of the Throttle valve position motor relay - short circuit. This is the manufacturer-specific definition used by Nissan.

The control module detected a fault associated with the Oxygen Sensing circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by Porsche.

The control module detected that the air-fuel mixture stayed leaner than the target despite full corrective control (Long Term Fuel Trim Adjustment Bank 1 System). This is the manufacturer-specific definition used by Audi.

The control module detected that the air-fuel mixture stayed leaner than the target despite full corrective control (Long Term Fuel Trim Adjustment Bank 1 System). This is the manufacturer-specific definition used by Volkswagen.

The control module detected improper operation of the Engine control module (ECM) - internal. This is the manufacturer-specific definition used by Volvo.
