C1112 KIA Code - Sensor Source Voltage

Quick Answer

The C1112 diagnostic trouble code (DTC) for KIA vehicles refers to an issue with the sensor source voltage. Common causes include Faulty Sensor: A malfunctioning sensor could be sending incorrect voltage readings to the ECM, Wiring Issues: Damaged or corroded wiring connecting the sensor to the ECM can disrupt the voltage signal, ECM/PCM Problems: Issues with the Engine Control Module or Powertrain Control Module can interfere with sensor readings. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code C1112 KIA Description

The C1112 diagnostic trouble code (DTC) for KIA vehicles refers to an issue with the sensor source voltage. This code indicates that the voltage from a sensor in the vehicle's system is not within the expected range. The sensor source voltage is crucial for providing accurate data to the vehicle's onboard computer, which then uses this information to make critical decisions regarding engine performance, emissions, fuel efficiency, and overall drivability.
