P1102 — Manifold Absolute Pressure sensor/EGR system fault

System: Powertrain  |  Type: Manufacturer-Specific  |  Make: Kia

About P1102

P1102 is a manufacturer-specific powertrain diagnostic trouble code recorded for Kia vehicles. It belongs to the P-prefix family of codes, which covers engine, transmission, emissions, or fuel-system faults.

When P1102 is stored, the module has detected a sensor-related fault — the reported value from the named sensor is out of spec.

Scanning & clearing: A generic OBD-II scan tool will usually read and clear powertrain (P) codes. For live data, freeze-frame capture, and bi-directional tests you may need a more capable scan tool that supports the vehicle's ECM protocol.

P1102 is a manufacturer-specific code. The same code string on a different make may have a different meaning. Always confirm the code's definition against the vehicle's service information for the specific make and model under test.

Code Information

In Kia vehicles the P1102 fault code relates to the Manifold Absolute Pressure (MAP) sensor, with emphasis on the third mode of EGR (Exhaust Gas Recirculation) operation. The code is set when the Engine Control Module (ECM) detects an implausible or out of range MAP sensor signal during EGR Mode 3 self testing. The MAP sensor measures pressure inside the intake manifold, and the ECM relies on this reading to calculate engine load, regulate EGR flow, and control fuelling for emissions compliance. When this code is set the driver may notice rough idle, hesitation, reduced power, increased fuel c...
