P0105 KIA Code - Manifold Absolute Pressure/Barometric Pressure Circuit Malfunction
Quick Answer
The Manifold Absolute Pressure (MAP) sensor measures the pressure inside the intake manifold. Common causes include Faulty Manifold Absolute Pressure (MAP) Sensor, Manifold Absolute Pressure Sensor harness is open or shorted, Manifold Absolute Pressure Sensor circuit poor electrical connection. 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 P0105 KIA Description
The MAP sensor wiring includes 3 circuits. The Engine Control Module (ECM) supplies a regulated 5 volts to the sensor on a 5 V reference circuit. The ECM supplies ground on a low reference circuit. The MAP sensor provides a signal voltage to the ECM, relative to the pressure changes, on the MAP sensor signal circuit. The ECM converts the signal voltage input to a pressure value.
Under normal operation the greatest pressure that can exist in the intake manifold is at ignition ON, engine OFF, which is equal to the BARO. The lowest manifold pressure occurs when the vehicle is idling or decelerating. The ECM monitors the MAP sensor signal for pressure outside of the normal range.
The Diagnostic Trouble Code (DTC) will be set when the ECM receives an excessively low or high voltage from the MAP Sensor.
What are the Possible Causes of the DTC P0105 KIA?
- Faulty Manifold Absolute Pressure (MAP) Sensor
- Manifold Absolute Pressure Sensor harness is open or shorted
- Manifold Absolute Pressure Sensor circuit poor electrical connection
- Faulty Engine Control Module (ECM)
How to Fix the DTC P0105 KIA?
Review the 'Possible Causes' above and visually examine the corresponding wiring harness and connectors. Check for damaged components and inspect connector pins for signs of being broken, bent, pushed out, or corroded.
What is the Cost to Diagnose the Code?
Labor: 1.0
To diagnose the P0105 KIA code, it typically requires 1.0 hour of labor. Rates vary by location, vehicle, and shop. Many shops charge between $80–$150 per hour; dealerships and metro areas may be higher, independents may be lower.

Frequently Asked Questions about P0105 KIA Code
1. What does the P0105 code mean on a Kia?
The P0105 code indicates a malfunction in the manifold absolute pressure (MAP) or barometric pressure (BARO) circuit, which helps the engine control module (ECM) manage air-fuel ratios and engine performance.
2. What are the common symptoms of a P0105 code in a Kia?
Symptoms may include poor engine performance, rough idling, stalling, reduced fuel efficiency, hesitation during acceleration, and the check engine light being illuminated.
3. What causes the P0105 code in a Kia?
Common causes include a faulty MAP sensor, damaged wiring or connectors in the MAP sensor circuit, vacuum leaks, or issues with the ECM.
4. How do I diagnose the P0105 code on my Kia?
Start by checking the MAP sensor and its wiring for damage, test the sensor’s voltage and signal, inspect for vacuum leaks, and verify the ECM is functioning properly.
5. Can I drive my Kia with the P0105 code?
Driving with the P0105 code is not recommended, as it can lead to poor engine performance, potential stalling, and increased emissions, which may cause further damage.
6. How do I fix the P0105 code on my Kia?
Repairs may include replacing the MAP sensor, repairing damaged wiring or connectors, fixing vacuum leaks, or reprogramming or replacing the ECM if necessary.
7. Is the P0105 code specific to Kia vehicles?
No, the P0105 code is a generic OBDII code that applies to most vehicle makes and models, but the exact diagnostic and repair process may vary between vehicles.
8. How much does it cost to fix the P0105 code on a Kia?
Repair costs vary depending on the cause but typically range from $100 to $300 for a new MAP sensor. Wiring repairs or ECM replacement can increase costs significantly.
9. Can a dirty air filter cause the P0105 code on my Kia?
While a dirty air filter is unlikely to directly trigger P0105, it can contribute to airflow issues that may indirectly affect the MAP sensor’s performance.
10. Do I need to clear the P0105 code after fixing my Kia?
Yes, after completing the necessary repairs, use an OBDII scanner to clear the code and verify that it does not return during a test drive.
