P1114 Acura Code - Engine Coolant Temperature Sensor Circuit Intermittent Low Voltage
Quick Answer
The P1114 code for Acura vehicles indicates a problem with the Engine Coolant Temperature (ECT) Sensor Circuit, specifically indicating intermittent low voltage. Common causes include Faulty ECT Sensor: The ECT sensor itself may be malfunctioning, providing inaccurate temperature readings to the ECM, Damaged Wiring or Connectors: Wiring or connectors in the ECT sensor circuit could be damaged, leading to intermittent low voltage readings, ECM Issues: Problems with the ECM, such as a software glitch or hardware failure, could also cause the P1114 code. 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 P1114 Acura Description
The P1114 code for Acura vehicles indicates a problem with the Engine Coolant Temperature (ECT) Sensor Circuit, specifically indicating intermittent low voltage. The ECT sensor is a crucial component that measures the temperature of the engine coolant and sends this information to the engine control module (ECM). The ECM uses this data to adjust fuel delivery and ignition timing, ensuring optimal engine performance and efficiency.
Common Causes of P1114 Acura
- Faulty ECT Sensor: The ECT sensor itself may be malfunctioning, providing inaccurate temperature readings to the ECM.
- Damaged Wiring or Connectors: Wiring or connectors in the ECT sensor circuit could be damaged, leading to intermittent low voltage readings.
- ECM Issues: Problems with the ECM, such as a software glitch or hardware failure, could also cause the P1114 code.
- Coolant Leaks: Low coolant levels or coolant leaks can affect the accuracy of ECT sensor readings, triggering the code.
Symptoms of P1114 Acura
- Check Engine Light: The most common symptom associated with the P1114 code is the illumination of the Check Engine Light on the vehicle's dashboard.
- Poor Fuel Economy: Incorrect temperature readings from the ECT sensor can lead to inefficient fuel delivery, resulting in decreased fuel economy.
- Rough Idling: The engine may idle roughly or inconsistently due to inaccurate temperature data affecting fuel mixture and ignition timing.
- Difficulty Starting: Faulty temperature readings can cause difficulties in starting the engine, especially in cold weather.
- Engine Overheating: In extreme cases, the engine may overheat due to incorrect temperature readings, posing a risk of damage to engine components.
How to Fix P1114 Acura
- Diagnostic Testing: The first step in repairing the P1114 code is to perform diagnostic testing to pinpoint the exact cause of the issue. This may involve checking the ECT sensor, wiring, connectors, and ECM for faults.
- ECT Sensor Replacement: If the ECT sensor is found to be faulty, it will need to be replaced with a new, functioning sensor.
- Repair Wiring or Connectors: Damaged wiring or connectors in the ECT sensor circuit should be repaired or replaced to ensure proper voltage readings.
- ECM Reprogramming or Replacement: In cases where the ECM is the source of the issue, reprogramming or replacing the ECM may be necessary to resolve the code.
Cost to Fix P1114 Acura
The cost of repairing the P1114 code for an Acura vehicle can vary depending on the specific cause of the issue and the extent of repairs needed. On average, the cost of replacing an ECT sensor ranges from $100 to $200, while repairing wiring or connectors may cost between $50 and $150. If the ECM requires reprogramming or replacement, this can add several hundred dollars to the total repair cost.
