Code P1112 Chrysler Description
The P1112 Chrysler code refers to the Intake Air Temperature Sensor Circuit Intermittent Low Voltage. This code indicates that the intake air temperature sensor, which is responsible for monitoring the temperature of the air entering the engine, is reporting a low voltage intermittently. The intake air temperature sensor plays a crucial role in the engine's performance by providing data to the engine control module (ECM) to adjust the air-fuel mixture for optimal combustion. When the sensor reports low voltage intermittently, it can lead to incorrect air-fuel mixture adjustments, resulting in poor engine performance, decreased fuel efficiency, and increased emissions.
Common Causes of P1112 Chrysler
- Faulty Intake Air Temperature Sensor: The sensor may be malfunctioning, providing incorrect readings to the ECM.
- Wiring or Connector Issues: Damaged wiring or connectors leading to the intake air temperature sensor can cause intermittent low voltage readings.
- ECM Malfunction: A problem with the engine control module can also trigger the P1112 code.
- Intake Air Temperature Sensor Placement: Incorrect placement or mounting of the sensor can lead to inaccurate readings and trigger the code.
- Environmental Factors: Extreme temperatures or exposure to moisture can also affect the intake air temperature sensor's performance.
Symptoms of P1112 Chrysler
- Check Engine Light: The most common symptom associated with the P1112 code is the illumination of the check engine light on the vehicle's dashboard.
- Poor Engine Performance: The engine may exhibit hesitation, rough idling, or stalling due to incorrect air-fuel mixture adjustments.
- Decreased Fuel Efficiency: A faulty intake air temperature sensor can lead to decreased fuel efficiency as the engine may not be running at its optimal performance level.
- Increased Emissions: Incorrect air-fuel mixture adjustments can result in increased emissions from the vehicle's exhaust system.
How to Fix P1112 Chrysler
- Diagnose the Issue: Use a diagnostic scanner to retrieve the fault codes and perform a thorough inspection of the intake air temperature sensor, wiring, and connectors to identify the root cause of the problem.
- Replace Intake Air Temperature Sensor: If the sensor is found to be faulty, replace it with a new one following the manufacturer's guidelines.
- Check Wiring and Connectors: Inspect the wiring and connectors for any damage or corrosion, repair or replace as necessary.
- Clear Fault Codes: Once the repair is completed, clear the fault codes from the ECM memory using a diagnostic scanner to reset the check engine light.
- Test Drive: After the repair, test drive the vehicle to ensure that the issue has been resolved and that the engine is performing optimally.
Cost to Fix P1112 Chrysler
The typical repair costs for addressing the P1112 Chrysler code can range from $100 to $300, depending on the cost of the intake air temperature sensor, labor charges, and any additional parts or repairs needed. It is essential to consider that diagnosis time and labor rates at auto repair shops can vary, with hourly rates typically ranging between $80 and $150. Rates may be higher at dealerships or metropolitan areas and lower at independent shops. For a more precise cost estimate, it is advisable to check local rates and consult with a trusted auto repair professional.
