Ford E-350 Econoline Intake Air Temperature Sensor Guide (1995-2000)
Everything you need to know about replacing the Intake Air Temperature Sensor on your 1995-2000 Ford E-350 Econoline.
- A bad IAT sensor will cause poor fuel economy and performance issues like rough idle and hesitation.
- This is a very simple and inexpensive DIY repair that usually takes less than 15 minutes.
- The sensor is located on the air intake tube between the air filter box and the engine.
- Quality aftermarket brands like Standard Ignition (SMP) are a reliable and cost-effective choice for this part.
Is it an Intake Manifold Temperature Sensor or an Intake Air Temperature (IAT) Sensor?
You might see this part called by a few different names, including Engine Intake Manifold Temperature Sensor, Air Charge Temperature Sensor, or simply IAT Sensor. They all refer to the same component that measures the temperature of the air going into your engine. For your 1995-2000 Ford E-350 Econoline, this is a standalone sensor, not to be confused with the Engine Coolant Temperature (ECT) sensor, which measures coolant temperature instead.
Symptoms of a Failing IAT Sensor
When the IAT sensor starts to fail, it sends incorrect information to the engine's computer. This can cause a variety of noticeable problems. The most common sign is the Check Engine Light turning on. You may also experience poor fuel economy, a rough idle, hesitation when you accelerate, or difficulty starting the engine, especially when it's cold. In some cases, you might notice black smoke from the exhaust, which indicates a rich fuel mixture.
Don't Ignore a P0113 Code
A common trouble code associated with a failing IAT sensor is P0113 (Intake Air Temperature Sensor 1 Circuit High Input). This code means the computer is seeing a signal that indicates an extremely low temperature (like -40°F), 🎬 See how to diagnose a P0113 code using thermistor testing. which it knows is incorrect. Ignoring this can lead to fouled spark plugs and a no-start condition, particularly in cold weather.
Choosing the Right Aftermarket Sensor
For a vehicle like the 1995-2000 E-350, aftermarket IAT sensors offer a reliable and cost-effective alternative to OEM parts. The technology in these sensors is straightforward, and quality aftermarket brands meet or exceed original specifications.
- Standard Ignition (SMP): Standard Motor Products is a well-respected brand in the aftermarket industry. They are known for producing quality parts that are often considered equivalent to OEM standards. Many professional mechanics use SMP parts with confidence. Their non-"T-Series" parts are generally regarded as high-quality.
- True Tech: While search results show reviews for repair shops named True Tech, there is limited information available about a specific parts brand named "True Tech." It may be a private label or economy brand. For a critical-but-simple sensor like the IAT, it could be a budget-friendly option, but Standard Ignition is the more established and widely trusted brand.
Pro Tip: The IAT sensor for your E-350 is a simple, two-wire sensor. Before replacing it, check the wiring and connector for damage or corrosion, as this can cause the same symptoms as a bad sensor. Also, ensure your air filter is clean, as a clogged filter can sometimes affect sensor readings.
