P0098 2019 Ford F150 Code - Intake Air Temperature Sensor 2 Circuit High Voltage Bank 1

P0098 indicates that the Engine Control Module (ECM) has detected a high voltage input from the Intake Air Temperature Sensor 2 in Bank 1, which suggests that the sensor might be malfunctioning or there is an issue in the sensor circuit.

Symptoms can include a check engine light, reduced engine performance, poor fuel economy, and potential issues with the engine starting or running smoothly.

Common causes include a faulty intake air temperature sensor, wiring issues like shorts or opens in the sensor circuit, or problems with the ECM itself.

Diagnosis should start with scanning and recording the freeze frame data. Then, visually inspect the sensor and circuit for any obvious damage. Use a multimeter to check for proper voltage and ground at the sensor, and consider checking the sensor's resistance to ensure it matches manufacturer specifications.

Repair might involve replacing the intake air temperature sensor, repairing or replacing damaged wires in the sensor circuit, or in rare cases, replacing or reprogramming the ECM.

While you may be able to drive with this code active, it's not recommended as it can lead to poor engine performance, increased fuel consumption, and potential long-term damage to the engine.

Yes, it is fairly serious because it affects the engine's ability to accurately read air temperature, which can alter fuel mixture and engine performance, potentially leading to further engine damage if not addressed.

Tools needed may include a digital multimeter, a scan tool, basic hand tools for accessing the sensor, and possibly a wiring diagram for tracing the circuit issues effectively.

The frequency of this code can vary based on maintenance habits, environmental conditions, and the quality of the components used in the intake air temperature system. Proper maintenance and use of quality parts can help reduce the occurrence of this issue.
