Overview

The intake air temperature sensor is a two-wire thermistor sitting in the intake tract. It tells the ECU how warm the incoming air is, and the ECU uses that to correct fuel injection for air density — cold air is denser, so it needs more fuel. When the element drifts or fails, the ECU stops trusting it and substitutes a fixed default temperature, so the engine runs on a guessed value: cold starts get rough, the mixture goes rich, fuel economy drops, and the check engine light comes on with an intake air temperature code. This one arrives as a pair — the sensor plus a matching two-wire connector pigtail — because the plastic latch on a twenty-year-old plug is usually the part that breaks first.

Vehicle fitment & specifications

Features

Reports intake air temperature
The thermistor element tracks the temperature of the incoming charge and sends it to the ECU as a voltage signal, which the ECU uses to correct injection for air density.

Connector included
The matching two-wire pigtail comes with it, so a brittle or broken plug gets replaced instead of taped up — the pigtail's leads join your existing harness wiring.

ABS housing
An ABS body that stands up to heat and oil mist in the intake tract, and holds the element steady in the airstream for a long service life.

Direct replacement
The sensor fits the original mounting point and plugs straight in, with no programming. The spare pigtail is there for when the original connector is the broken part.

Fitment check

Listed for the 1996-2000 Civic, 1996-1997 del Sol and 2000-2006 Insight. Honda used more than one intake air temperature sensor number across these applications, so the number on your original sensor is the fastest check — compare it against the three OE numbers above before ordering.

What's in the box

• 1 intake air temperature sensor
• 1 connector pigtail (2-wire lead)

FAQ

What are the signs the sensor has failed?
A check engine light with an intake air temperature code — P0111, P0112 or P0113 on most OBD-II Hondas — plus a rough or hunting idle, a hard cold start, a rich smell at the tailpipe, hesitation when you accelerate, and fuel economy that drops for no obvious reason.

Do I need the connector as well as the sensor?
If the original plug's latch has gone brittle or snapped, yes. A connector that will not lock in place gives an intermittent reading — the sensor is fine, the connection is not. The pigtail in this set replaces the plug; its two leads join your existing wiring with a crimp or a solder joint.

Does it need programming or a relearn?
No. It is a passive two-wire sensor with nothing to flash. Fit it, clear the code and drive — the ECU reads it from the first start.

Will it fit my car?
Check your model and year against the fitment table first, then compare the number on your original sensor against the OE numbers listed above. If the number is not on the list, this is not the right sensor for your car.

Is this a genuine Honda part?
No — it is an aftermarket replacement cross-referenced to the OE numbers above. It is built to the same fitment and function, but it does not come in Honda packaging.
