How To Fix P0099 Code - Intake Air Temperature Sensor 2 Circuit Intermittent Fix
Dealing with an intermittent check engine light can be tricky, especially with code P0099, which stands for Intake Air Temperature Sensor 2 Circuit Intermittent. This code often appears after routine maintenance, such as replacing an air filter, if the sensor connector is not fully seated or the wiring is damaged. We discuss how this intermittent signal disrupts the fuel delivery strategy, leading to symptoms like reduced gas mileage, engine hesitation, or rough idling. This guide walks you through a visual inspection of the air intake pipe and wiring harness, specifically looking for loose plugs or corrosion near the battery. We also demonstrate how to use a scan tool alongside an infrared thermometer to compare actual intake temperatures against what the computer sees. By performing these checks, including a wire wiggle test, you can pinpoint whether the fault lies in the sensor connector or the wiring harness itself.
