🔍 What is P0110?

P0110 indicates a malfunction in the IAT sensor circuit, meaning the ECU is not receiving proper intake air temperature information from the sensor.

The IAT sensor helps the ECU adjust:

▶︎ Fuel injection

▶︎ Ignition timing

▶︎ Engine performance and efficiency

When this data is incorrect or missing, engine performance can suffer.

⚠️ Why Does the P0110 Code Appear?

P0110 is triggered when the ECU detects:

▶︎ No signal from the IAT sensor

▶︎ A signal outside the normal temperature range

▶︎ An electrical issue in the IAT sensor circuit

🔧 Common Causes of P0110

▶︎ Faulty or failed IAT sensor

▶︎ Damaged, shorted, or open wiring

▶︎ Corroded or loose sensor connector

▶︎ Intake air leaks affecting sensor readings

▶︎ ECU reference voltage or ground issues
