P0110

Intake Air Temperature (IAT) Sensor Circuit

Q: What does fault code P0110 mean?

Intake Air Temperature (IAT) Sensor Circuit. The intake air temperature sensor signal is outside the normal operating range (typically beyond -40°C to 150°C).

Q: What are the possible causes of P0110?

IAT sensor internal open or short; Sensor wiring open or short; Sensor connector poor contact; ECM internal fault.

Severity: Low Fuel & Air Metering Generic Code

Detailed Description

The intake air temperature sensor signal is outside the normal operating range (typically beyond -40°C to 150°C).

Possible Causes

IAT sensor internal open or short

Sensor wiring open or short

Sensor connector poor contact

ECM internal fault.

Solutions & Repair Guide

Measure IAT sensor resistance at different temperatures (approximately 2-3k ohm at 20°C, 200-400 ohm at 80°C); Check wiring continuity; Replace the sensor if resistance values are abnormal.
