If your car is hesitating off the line, idling roughly, or throwing a check engine light, the intake air temperature sensor (IAT sensor) is worth looking at. The sensor sits in the intake tract, often in the air filter housing or the intake manifold, reading air temperature and feeding it to the ECU so the fuel mixture and ignition timing can be adjusted.A faulty IAT sensor confuses the ECU enough to flood the engine with fuel or starve it altogether, which over time fouls plugs and damages the catalytic converter. Tracking down the right replacement is fiddly, since IAT sensors look near-identical across models but differ in connector, thread, and resistance curve.Parthunt24 brings used intake air temperature sensor listings together from marketplaces like eBay, Ovoko, RicambiPro, Opisto, Proxyparts, Ecooparts, Autoparts-24, Totalparts. Compare 26 options on price, condition, and fitment, then head to the marketplace once you've found the right sensor.

How to choose the right Intake Air Temperature Sensor for your car?

The Intake Air Temperature (IAT) sensor measures the temperature of incoming air to the engine, allowing the ECU to optimise the air-fuel mixture, fuel efficiency, and ignition timing. Using a thermistor, it sends real-time data to the ECU, which is crucial because cold air is denser than warm air and requires more fuel.Two sensors that look the same can have different pin counts or resistance curves, so always cross-check the OEM part number. Note whether your car runs a standalone IAT or one integrated into the MAF housing, as the two aren't interchangeable.Pick your make and model from the filter panel down the left of the Parthunt24 results page to trim the list. Each entry leads back to the original marketplace, where the seller's full breakdown and the purchase option live.

Vehicle & engine compatibility: Match make, model, year, engine code, and OEM part number.
Sensor type: Standalone IAT vs integrated with MAF sensor.
Connector type: Verify plug shape, pin count, and wiring compatibility.
Mounting design: Threaded sensor vs push-fit (clip-in) type.
Sensor range: Ensure the correct temperature range and resistance curve.
ECU compatibility: Must match engine control unit calibration.
Location: Confirm fit for the intake manifold, air duct, or airbox position.
Thread size: Verify the correct thread diameter and pitch where applicable.
Seal type: Check O-ring or gasket compatibility to prevent air leaks.

What to check before buying an Intake Air Temperature Sensor

When the seller's listing loads, the detail it shows is what decides whether the sensor is worth ordering. An IAT sensor that reads inaccurately will still bolt up cleanly and pass a visual test, so testing notes from the seller carry more weight than they do on most parts.

Photos: Clear shots of the sensor body, connector, and any threading.
Seller reputation: Feedback rating, time selling, and reviewer comments.
Compatibility: OEM number checked against your engine code.
Included components: Sensor only, or with O-ring, gasket, or pigtail?
Condition: Wear, corrosion at the connector, signs of heat damage.
Testing: Confirmation the sensor was reading correctly on the donor car.
Warranty and returns: A clear path if the part is wrong or faulty.

If the details stack up, finish the order directly with the seller.

How much does an Intake Air Temperature Sensor cost?

Intake air temperature sensor price varies with the vehicle and sensor type. Used standalone IAT sensors open at €5-€15, integrated MAF-and-IAT modules sit at €30-€80, and OEM units for premium or specialist applications push past €100.Searching Parthunt24, intake air temperature sensor listings start from as low as 5.00. Factors that move the intake air temperature sensor price up or down:

Type: Standalone IAT sits below integrated MAF-and-IAT modules.
Brand: OEM and Bosch sit at the top; quality aftermarket sits below.
Vehicle rarity: Common engines are cheaper; specialist applications cost more.
Inclusions: O-rings, pigtails, or fitting kits bundled add to the price.

Lining up IAT sensor prices on Parthunt24 surfaces the cheapest viable option in seconds.

Faulty Intake Air Temperature Sensor? Time to inspect these other parts too

IAT faults rarely show up on its own. Cracked intake pipework or a dirty MAF can produce identical symptoms to a failed IAT sensor, so check the whole air path before fitting a new one. Browse these on Parthunt24 alongside the sensor:

ECU: Bad data confuses the ECU; in rare cases the unit itself is at fault.
MAF: Often shares a housing with the IAT on modern cars.
MAP sensor: Worth checking when the IAT is throwing codes.
Intake ducting: Cracks let in unmetered air and skew readings.
Air filter housing: Cracks at the seam produce similar symptoms.
