What is P0110?
The diagnostic trouble code (DTC) P0110 indicates a malfunction in the Intake Air Temperature (IAT) sensor circuit. This sensor plays a crucial role in regulating the air-fuel mixture entering your engine, which is vital for maintaining optimal engine performance and efficiency. The IAT sensor measures the temperature of the air entering the engine and sends this data to the Engine Control Module (ECM). If the ECM detects that the readings are out of the expected range or if there’s a fault in the circuit itself, it triggers the P0110 code. Common symptoms include a check engine light illuminating, decreased fuel efficiency, and engine performance issues such as hesitation during acceleration or rough idling. This code can lead to more serious engine performance problems if left unaddressed, causing potential damage to the engine over time. Vehicle owners should be aware that common makes and models affected by this code include the 2010-2015 Ford F-150 and 2013-2017 Toyota RAV4, among others. Addressing this issue promptly can save you from costly repairs down the line and ensure that your vehicle runs smoothly.
System: P - Powertrain (Engine, Transmission, Emissions)
Symptoms
Common symptoms when P0110 is present:
- Check engine light stays on constantly, indicating a fault detected in the IAT sensor circuit.
- Engine hesitates during acceleration, leading to a lack of power and responsiveness.
- Fuel economy decreased by 10-15%, resulting in more frequent trips to the gas station.
- Rough idling or stalling, particularly when the engine is warming up.
- Increased emissions output, which could lead to failing emissions testing.
Possible Causes
Most common causes of P0110 (ordered by frequency):
- Faulty IAT sensor (60% likelihood) - The most common cause is a malfunctioning IAT sensor that fails to provide accurate temperature readings.
- Wiring issues (20% likelihood) - Damaged or corroded wiring or connectors in the IAT sensor circuit can disrupt communication with the ECM.
- ECM malfunctions (10% likelihood) - Although less common, a failing ECM can misinterpret sensor data or fail to receive it altogether.
- Air intake leaks (5% likelihood) - Leaks in the air intake system can lead to inaccurate temperature readings.
- Other sensor failures (5% likelihood) - Malfunctions in related sensors, such as the Mass Air Flow (MAF) sensor, can also trigger P0110.
