If the ECM detects out of range IAT sensor 1 and 2 readings, the P2199 code is set. The code indicates a correlation issue between the two IAT sensors. It is important to address this issue promptly to avoid potential engine damage.

If you have been faced with diagnosing a code P2199, you need to know that it means that the powertrain control module (PCM) has detected a discrepancy in the correlating signals between two separate intake air temperature (IAT) sensors.

Jun 14, 2020 · The Engine Control Module (ECM) monitors the Intake Air Temperature (IAT) sensor reading closely. The P2199 code is set when the ECM detects out of range IAT sensor 1 and 2 readings. P2199 Code - Intake Air Temperature Sensor 1/2 Correlation

Sep 20, 2022 · What could cause the OBDII code P2199 in a Chevrolet indicating an issue with the Intake Air Temperature Sensor 1-2 Not Plausible? - Possible causes include a faulty intake air temperature sensor, wiring issues, sensor connections problems, or a problem with the engine control module (ECM).

Apr 26, 2024 · The P2199 trouble code indicates a specific issue with the Intake Air Temperature (IAT) Sensor 1 in your vehicle, specifically reporting that the sensor is reading unusually high temperatures for Bank 2 of the engine.

The OBD2 code P2199 indicates an issue with the correlation between the intake air temperature (IAT) sensor readings, suggesting a discrepancy in the air temperature data being sent to the vehicle’s Engine Control Module (ECM).

The P2199 OBD-II trouble code indicates that two of your intake air temperature sensors are not correlating correctly, possibly sending out-of-range readings.

Jan 3, 2025 · When the Engine Control Module (ECM) detects a significant discrepancy between the readings from IAT Sensor 1 and IAT Sensor 2, it triggers the P2199 code. This can lead to various performance issues and may illuminate the check engine light on your dashboard.

To resolve the P2199 code concerning the intake air temperature sensor 1/2 correlation, start by using a scan tool to check ECM codes. After clearing codes, test drive to replicate conditions.

The P2199 code indicates that the ECM has detected a discrepancy between the readings of the IAT sensor 1 and 2, which are usually located before and after the throttle body, respectively. The engine may also show symptoms such as hesitation, stalling, rough idle, or poor acceleration.
