The intake air temperature (IAT) sensor on a 2007 Dodge Caliber is located in the air intake path, usually in the tube between the air filter box and the throttle body. In most configurations it’s a separate two‑wire sensor mounted in the intake tube; some models may have the IAT integrated with the mass air flow (MAF) sensor assembly near the throttle body.
Understanding the exact placement helps with diagnostics, replacement, and troubleshooting. Engine options for the Caliber in 2007 can vary, so there are two common possibilities you may encounter.
Typical locations by engine configuration
Use this quick guide to locate the IAT sensor on common 2007 Caliber setups. Depending on your exact engine, it may be in the intake tube or part of the MAF housing.
- In the air intake hose: a small sensor mounted in the plastic tube between the air box and the throttle body, usually with a two‑wire connector.
- Integrated with the MAF housing: on some configurations, the IAT is built into the MAF sensor assembly near the throttle body.
Finding the sensor in one of these locations will allow you to inspect the connector, test resistance/voltage, or replace the sensor if needed. If you’re unsure which configuration your Caliber uses, check under the hood or consult the vehicle’s service manual for the exact engine code.
How to identify and test quickly
Look for a two‑wire or small 3–wire connector on the intake tube or MAF unit. If you have access to a scan tool, check for IAT-related trouble codes (for example, P0112 to P0119 range) and monitor live IAT readings to verify normal operation. A misreading IAT can affect air‑fuel mixtures and idle performance.
Notes for different model years and trims
Though the Dodge Caliber lineage shares many parts, there can be minor variations by production date and trim level. If the sensor isn’t obvious in the intake tube, confirming the engine code (for example 2.0L or 2.4L World engine) and referencing the factory manual or a reliable parts diagram will reveal whether the IAT is a separate piece or integrated with the MAF sensor.
Summary
For a 2007 Dodge Caliber, the intake air temperature sensor is typically located in the intake tract—most often in the air intake hose between the air box and the throttle body. In some engines it may be part of the MAF sensor assembly rather than a separate component. Identifying the correct location is essential for testing, cleaning, or replacement, and using a scan tool can help confirm operation and diagnose related performance issues.
