The two pin intake temperature sensor in your Honda Civic is there to measure the air temperature. Based on this signal your Honda Engine Control Unit (ECU) will increase or adjust the amount of fuel being delivered to your 1.6 liter SOHC engine. When this sensor fails, your engine computer will not be able to read the intake temperature, and thus lose the ability to adjust properly.

Depending on your Civic the Intake Air Temperature (IAT) sensor can be mounted in the intake tract, or your air filter box. Today I’ll be showing you how to replace your IAT sensor in a 1996 Honda Civic.

When the IAT sensor in your Honda goes out, one of the first indications of trouble will be a check engine light turned on in your instrument cluster.
