Your 1995-2000 Ford Contour Intake Air Temperature Sensor Explained
A failing intake air temperature sensor can cause poor gas mileage and rough running in your Ford Contour.
- A bad IAT sensor on your Contour will most likely trigger a Check Engine Light with codes P0112 or P0113.
- Symptoms include poor gas mileage, rough idle, and hesitation.
- Replacement is very easy for a DIYer, requiring basic tools and taking less than 30 minutes.
- Quality aftermarket brands like NGK and Standard Ignition offer reliable performance without the OEM price.
Is Your Contour's IAT Sensor Failing?
A bad Intake Air Temperature (IAT) sensor sends wrong information to your car's computer. This can make your engine run too rich (too much fuel) or too lean (not enough fuel). The most common sign of a problem is the check engine light turning on. You might also notice other performance issues that make your car frustrating to drive.
Choosing the Right Aftermarket Sensor
For a 1995-2000 Ford Contour, you don't need to buy the most expensive sensor to get a reliable part. The original technology is simple, and aftermarket brands offer excellent quality. Aftermarket sensors are designed to meet or exceed OEM specifications. Here’s a breakdown of the available brand tiers.
Premium Aftermarket (OEM Quality)
NGK (NTK): NTK is the sensor brand for NGK, a company famous for its spark plugs. They are a high-quality OEM supplier for many car manufacturers. Choosing an NGK/NTK sensor is like getting an OEM-quality part without the dealership price tag. They are known for reliability and accurate performance.
Standard Aftermarket (Trusted Quality)
Standard Ignition (SMP): Standard Motor Products is a major player in the aftermarket world and has been around for a long time. They produce reliable parts that are a trusted choice for professional mechanics and DIYers. A Standard Ignition sensor is a solid, dependable option that balances quality and cost effectively.
Economy Aftermarket (Budget-Friendly)
True Tech: This brand represents the most budget-friendly option. While specific reviews for this brand on this part are scarce, economy brands are typically best for situations where budget is the primary concern. They meet the basic requirements to get the car running properly, but may not have the same long-term durability or precise calibration as premium brands.

Frequently Asked Questions (FAQ)
Where is the IAT sensor located on my 1995-2000 Ford Contour?
The location can vary slightly. On many 4-cylinder (2.0L Zetec) models, the IAT sensor is screwed into the underside of the large plastic air intake resonator that sits over the engine. On other models, including some V6 (2.5L Duratec) versions, it may be located in the flexible intake boot between the air filter box and the throttle body. Look for a small, two-wire sensor plugged into the intake path.
What do the trouble codes P0112 and P0113 mean?
These are the two most common codes for a failing IAT sensor. P0113 (Circuit High Input) means the computer is seeing a high voltage, which it interprets as an extremely cold temperature (like -40°F). This is often caused by a faulty sensor or a break in the wiring. P0112 (Circuit Low Input) means the computer sees a low voltage, interpreting it as an extremely high temperature. This is often caused by a short in the wiring or a failed sensor.
Can I just clean the IAT sensor?
Sometimes, the sensor tip can get covered in dirt or oil, which can affect its readings. You can try cleaning it gently with a dedicated electrical parts or mass air flow sensor cleaner. However, if the sensor has failed internally, which is common, cleaning will not fix the problem and replacement is necessary.
What happens if I don't replace a bad IAT sensor?
Ignoring a bad IAT sensor will lead to a persistent check engine light, poor fuel economy, and rough engine performance. It can cause your engine to hesitate, idle poorly, or be hard to start. Over time, running with an incorrect air-fuel mixture can lead to other issues, like fouled spark plugs or damage to the catalytic converter.
