Is Your Venture Running Rough? It Could Be the IAT Sensor
If your Chevrolet Venture is experiencing poor fuel economy, a rough idle, or has trouble starting, a faulty Engine Intake Manifold Temperature Sensor could be the culprit. This small sensor plays a big role in how your engine runs. When it fails, it sends incorrect information to the engine's computer, leading to the wrong air-fuel mixture. This can cause a variety of noticeable problems.
Common Symptoms of a Bad IAT Sensor
A failing IAT sensor usually won't stop your van from driving, but it will cause performance and efficiency issues. Here are the most common signs:
- Check Engine Light: This is often the first sign. You may see codes like P0112 (circuit low) or P0113 (circuit high).
- Poor Fuel Economy: The engine may run too rich (too much fuel) or too lean (not enough fuel), wasting gas.
- Rough Idle: The engine may shake or idle unevenly, especially when first started.
- Hard Starting: The engine may take longer to crank and start, particularly in cold weather.
- Engine Hesitation: You might notice a lack of power or a sluggish response when you press the gas pedal.
A Note on Check Engine Code P0113
The code P0113 (Intake Air Temperature Sensor Circuit High Input) often points to an open circuit. This means the problem could be a broken wire or a corroded, unplugged connector, not necessarily a bad sensor. Always check the wiring and connector for damage before replacing the part.
Choosing the Right Aftermarket Sensor
For the 1997-2005 Venture, the IAT sensor is a simple and reliable part. There is little practical difference in quality between the original equipment (OEM) AC Delco part and a quality aftermarket replacement for this specific component.
- Standard Ignition: Standard Motor Products (SMP) is a well-regarded aftermarket manufacturer known for producing reliable sensors that meet or exceed OEM specifications. This is a dependable choice.
- True Tech: This brand is often a private-label or entry-level option. While it may function correctly, brands with a longer public track record like Standard are generally a safer bet for long-term reliability.
Given that the price difference between OEM and top-tier aftermarket brands is minimal for this part, choosing a reputable brand like Standard Ignition offers a good balance of cost and quality without any significant risk.

| New Aftermarket Sensor | $19 - $23 |
| New OEM (AC Delco) Sensor | $20 - $25 |

Frequently Asked Questions
Where is the IAT sensor located on a 1997-2005 Venture?
The IAT sensor is located in the large, flexible rubber air duct that runs between the air filter box and the engine's throttle body. It is a small, two-wire plastic sensor that pushes into a grommet in the duct.
Can I replace the IAT sensor myself?
Yes, this is a very easy DIY job. It requires no special tools beyond possibly a flathead screwdriver to loosen the air duct clamp if you need more room. The sensor itself can be unplugged and pulled straight out of the duct. The entire process takes less than 15 minutes.
Are there any recalls for the Venture IAT sensor?
No, searches of the NHTSA database show no recalls or widespread technical service bulletins (TSBs) for the intake air temperature sensor on the 1997-2005 Chevrolet Venture.
Can I just clean the IAT sensor?
While some sensors can be cleaned, the IAT sensor on a Venture rarely gets dirty enough to cause failure. Given the low cost of a new sensor, replacement is the most effective and reliable solution to ensure accurate readings.
