U1437 Jeep Code - Implausible Intake Air Temperature Message Recieved

Quick Answer

The U1437 diagnostic trouble code (DTC) for Jeep vehicles indicates an "Implausible Intake Air Temperature Message Received." This code is triggered when the Engine Control Module (ECM) detects a discrepancy between the intake air temperature sensor's signal and other related sensors' signals. Common causes include Faulty intake air temperature sensor, Wiring issues or poor connections in the intake air temperature sensor circuit, ECM software or hardware malfunction. 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 U1437 Jeep Description

The U1437 diagnostic trouble code (DTC) for Jeep vehicles indicates an "Implausible Intake Air Temperature Message Received." This code is triggered when the Engine Control Module (ECM) detects a discrepancy between the intake air temperature sensor's signal and other related sensors' signals. The intake air temperature sensor is responsible for measuring the temperature of the air entering the engine, which is crucial for determining the correct air-fuel mixture for combustion. An inaccurate intake air temperature reading can lead to poor engine performance, reduced fuel efficiency, and increased emissions.
