P0112 Scion Code - Intake Air Temperature Circuit Low Input
Quick Answer
The P0112 Scion code indicates that there is a problem with the Intake Air Temperature (IAT) sensor circuit, specifically that the input voltage is lower than the normal operating range. Common causes include Faulty IAT sensor, Damaged wiring or connectors in the sensor circuit, Corrosion or contamination in the sensor terminals. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P0112 Scion Description
The P0112 Scion code indicates that there is a problem with the Intake Air Temperature (IAT) sensor circuit, specifically that the input voltage is lower than the normal operating range. The IAT sensor is responsible for measuring the temperature of the air entering the engine intake manifold. This information is crucial for the engine control module (ECM) to adjust the air/fuel mixture for optimal combustion and performance.
Common Causes of P0112 Scion
- Faulty IAT sensor
- Damaged wiring or connectors in the sensor circuit
- Corrosion or contamination in the sensor terminals
- Malfunctioning ECM
- Air intake system leaks or restrictions
Symptoms of P0112 Scion
- Poor fuel efficiency
- Rough idling
- Hesitation or stalling
- Decreased engine performance
- Check Engine Light illuminated
How to Fix P0112 Scion
- Begin by visually inspecting the wiring and connectors in the IAT sensor circuit for any signs of damage or corrosion.
- Test the IAT sensor using a multimeter to check for proper resistance and voltage values.
- If the sensor is faulty, replace it with a new one and ensure it is properly calibrated.
- Clear the diagnostic trouble codes from the ECM using a scan tool and monitor the system for proper operation.
- Test drive the vehicle to ensure that the symptoms associated with the P0112 code have been resolved.
Cost to Fix P0112 Scion
The typical repair costs for addressing a P0112 Scion code can vary depending on the specific cause of the issue. On average, the cost of replacing an IAT sensor ranges from $50 to $150, while the cost of labor can range from $80 to $150 per hour. Additional costs may include diagnostic fees and any other necessary repairs or parts. It's advisable to consult with a trusted mechanic or repair shop to get a more accurate estimate based on the vehicle's make and model.

Frequently Asked Questions about P0112 Scion Code
What does the OBDII code P0112 mean for a Scion?
P0112 indicates that the Intake Air Temperature (IAT) sensor is reporting a voltage that is lower than expected, suggesting a possible circuit issue or sensor fault.
What are the common symptoms of P0112 in a Scion?
Symptoms may include poor engine performance, reduced fuel efficiency, rough idling, and difficulty starting the engine.
What causes the P0112 code in a Scion?
Common causes include a faulty IAT sensor, damaged wiring or connectors, a short circuit, or a sensor contaminated with dirt or debris.
Can a dirty air filter trigger the P0112 code?
Yes, a clogged or dirty air filter can affect airflow and potentially contribute to an incorrect IAT sensor reading.
How do you diagnose the P0112 code on a Scion?
Inspect the IAT sensor, wiring, and connectors for damage or corrosion. Use a multimeter to check sensor resistance and voltage readings against manufacturer specifications.
Can you drive with the P0112 code active?
Driving with P0112 is possible but not recommended as it may lead to reduced engine performance and long-term damage.
How do you fix the P0112 code on a Scion?
Common fixes include replacing the IAT sensor, repairing damaged wiring or connectors, cleaning the sensor, or replacing the air filter.
Does P0112 affect emissions in a Scion?
Yes, this code can affect emissions as incorrect air temperature readings may disrupt the air-fuel mixture, leading to higher pollutant output.
How much does it cost to fix the P0112 code?
Repair costs vary but typically range between $50 and $200, depending on whether you need to replace the IAT sensor or address wiring issues.
Can a bad IAT sensor cause engine overheating?
While it doesn’t directly cause overheating, a malfunctioning IAT sensor can lead to improper air-fuel mixture, which may indirectly affect engine temperature.
