Experiencing the P0113 code in your Dodge Ram can be frustrating, but understanding its causes and solutions is key to maintaining your vehicle’s performance. This comprehensive guide delves into the intricacies of the P0113 error, specifically tailored for Dodge Ram owners.
Decoding the Dodge Ram P0113 Error
The P0113 code in Dodge Rams indicates an issue with the Intake Air Temperature (IAT) sensor circuit. This sensor plays a crucial role in engine performance by helping the Engine Control Module (ECM) adjust the air-fuel mixture based on incoming air temperature. When the sensor reports a high input, it triggers the P0113 code.
Common Triggers for P0113
- Faulty IAT sensor
- Damaged wiring or connectors
- Short circuit in sensor wiring
- ECM malfunction (rare)
