Code P0117 2014 Toyota RAV4 Description
The P0117 code in a 2014 Toyota RAV4 indicates a problem with the engine coolant temperature circuit registering a low input. This code is typically triggered when the engine control module (ECM) receives a signal from the coolant temperature sensor that indicates the temperature of the engine coolant is lower than expected.
Common Causes of P0117 2014 Toyota RAV4
- Faulty Coolant Temperature Sensor: The most common cause of a P0117 code is a malfunctioning coolant temperature sensor that is providing inaccurate readings to the ECM.
- Wiring Issues: Damaged or corroded wiring connecting the coolant temperature sensor to the ECM can disrupt the signal and trigger the code.
- Low Coolant Level: Insufficient coolant in the engine can lead to inaccurate temperature readings and trigger the code.
- Faulty Thermostat: A malfunctioning thermostat can cause the engine to run at incorrect temperatures, leading to a low input from the coolant temperature sensor.
- ECM Malfunction: In rare cases, a problem with the engine control module itself can cause a P0117 code to be triggered.
Symptoms of P0117 2014 Toyota RAV4
- Check Engine Light: The most common symptom associated with a P0117 code is the illumination of the check engine light on the vehicle's dashboard.
- Poor Fuel Economy: A malfunctioning engine coolant temperature sensor can cause the engine to run inefficiently, leading to decreased fuel economy.
- Rough Idling: Incorrect temperature readings can result in rough idling or stalling of the engine, especially when the vehicle is at a stop.
- Engine Overheating: In severe cases, a low input from the coolant temperature sensor can cause the engine to overheat, leading to potential damage.
How to Fix P0117 2014 Toyota RAV4
- Diagnose the Issue: Begin by using a scan tool to read the code and identify the specific cause of the low input from the coolant temperature sensor.
- Inspect Coolant Temperature Sensor: Check the sensor for any signs of damage or corrosion and replace it if necessary.
- Check Wiring: Inspect the wiring connecting the sensor to the ECM for any breaks or damage and repair or replace as needed.
- Verify Coolant Level: Ensure the coolant level in the engine is sufficient and top up if necessary.
- Test Thermostat: Check the thermostat for proper operation and replace it if it is found to be faulty.
Cost to Fix P0117 2014 Toyota RAV4
The cost of repairing a P0117 code in a 2014 Toyota RAV4 can vary depending on the specific cause of the issue and the labor rates in your area. Typically, replacing a coolant temperature sensor can cost between $50 and $150, while addressing wiring issues or other potential causes may increase the overall cost. On average, the total repair cost for this issue, including parts and labor, can range from $100 to $300. It is recommended to consult with a qualified mechanic or auto repair shop to get an accurate estimate based on your vehicle's specific needs and local rates.

Frequently Asked Questions about P0117 2014 Toyota RAV4 Code
1. What does the OBDII code P0117 mean on a 2014 Toyota RAV4?
P0117 indicates that the Engine Control Module (ECM) has detected a low voltage signal from the Engine Coolant Temperature (ECT) sensor, suggesting the sensor is reading an abnormally low temperature.
2. What are common symptoms of code P0117 in a 2014 Toyota RAV4?
Symptoms may include the check engine light turning on, poor fuel economy, difficulty starting the engine, engine overheating, or the temperature gauge reading incorrectly.
3. What causes the P0117 code to appear on a 2014 Toyota RAV4?
Common causes include a faulty ECT sensor, damaged or corroded wiring, a bad electrical connection, or low coolant levels.
4. Can I drive my 2014 Toyota RAV4 with the P0117 code?
While it may be possible to drive, it is not recommended. This issue can lead to poor engine performance and potential overheating, which could cause serious engine damage.
5. How do you diagnose the P0117 code on a 2014 Toyota RAV4?
Diagnosing involves using a scan tool to check for stored codes, inspecting the ECT sensor and its wiring for damage, testing the sensor's resistance, and ensuring the coolant levels are adequate.
6. How do you fix the P0117 code in a 2014 Toyota RAV4?
Repairs may include replacing the ECT sensor, fixing damaged wiring or connectors, replenishing coolant, or replacing the ECM if it’s malfunctioning.
7. How much does it cost to fix the P0117 code on a 2014 Toyota RAV4?
Repair costs vary, but replacing the ECT sensor typically costs between $100 and $250, including parts and labor. Wiring repairs or coolant system fixes may vary in price.
8. Can a low coolant level cause the P0117 code in a 2014 Toyota RAV4?
Yes, low coolant levels can cause inaccurate readings from the ECT sensor, leading to the P0117 code.
