P117A Ford Code - Engine Oil Over Temperature - Forced Limited Power
Quick Answer
The P117A Ford diagnostic trouble code indicates that the engine oil temperature is too high, leading to forced limited power. Common causes include Low oil level: Insufficient oil in the engine can lead to increased friction and heat generation, causing the oil temperature to rise, Faulty oil cooler: A malfunctioning oil cooler can fail to adequately cool the engine oil, leading to overheating, Clogged oil passages: Dirt, debris, or sludge buildup in the oil passages can restrict the flow of oil, causing it to heat up. 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 P117A Ford Description
The P117A Ford diagnostic trouble code indicates that the engine oil temperature is too high, leading to forced limited power. This can be a serious issue as it can affect the overall performance of the vehicle and potentially cause long-term damage if not addressed promptly. When the engine oil temperature exceeds safe levels, the power output of the engine is reduced to prevent further damage. This code typically triggers the vehicle's engine control module (ECM) to limit power output and put the vehicle into a safe mode to prevent overheating of the engine oil.
Common Causes of P117A Ford
- Low oil level: Insufficient oil in the engine can lead to increased friction and heat generation, causing the oil temperature to rise.
- Faulty oil cooler: A malfunctioning oil cooler can fail to adequately cool the engine oil, leading to overheating.
- Clogged oil passages: Dirt, debris, or sludge buildup in the oil passages can restrict the flow of oil, causing it to heat up.
- Faulty oil temperature sensor: A defective oil temperature sensor can provide incorrect readings to the ECM, triggering the code.
- Engine running at high RPM for extended periods: Continuous high-speed driving or towing heavy loads can lead to increased engine oil temperature.
Symptoms of P117A Ford
- Reduced engine power: The vehicle may experience a significant decrease in power output, making it difficult to accelerate or maintain speed.
- Illuminated check engine light: The check engine light may come on to indicate a problem with the engine oil temperature.
- Engine overheating: The engine may start to overheat due to the high oil temperature, which can lead to further issues if not addressed.
- Engine knocking or pinging: High oil temperature can cause abnormal combustion inside the engine, leading to knocking or pinging noises.
- Poor fuel efficiency: The vehicle may start to consume more fuel than usual due to the reduced engine performance.
How to Fix P117A Ford
- Check engine oil level: Ensure that the engine oil level is within the recommended range and top up if necessary.
- Inspect and clean oil cooler: Check the oil cooler for any clogs or damage, clean it thoroughly, and replace it if needed.
- Check oil passages: Inspect the oil passages for any blockages or restrictions, and clean them out to ensure proper oil flow.
- Replace oil temperature sensor: If the oil temperature sensor is faulty, replace it with a new one to provide accurate readings to the ECM.
- Monitor engine load: Avoid running the engine at high RPM for extended periods to prevent overheating of the engine oil.
Cost to Fix P117A Ford
The cost of repairing the P117A Ford code can vary depending on the specific cause of the issue. On average, the repair costs for this issue can range from $200 to $500, including parts and labor. However, it's important to note that the actual cost may vary based on the location of the repair shop, the make and model of the vehicle, and the extent of the repairs needed. Additionally, diagnosis time and labor rates at auto repair shops can impact the overall cost, with rates typically ranging from $80 to $150 per hour. It's recommended to obtain quotes from multiple repair shops to get a more accurate estimate for the repair.

Frequently Asked Questions about P117A Ford Code
1. What does the OBDII code P117A mean on a Ford vehicle?
P117A indicates "Engine Oil Over Temperature - Forced Limited Power," meaning the engine oil temperature has exceeded safe limits, causing the system to reduce power to protect the engine.
2. What are the common symptoms of code P117A in a Ford?
Symptoms include reduced engine power (limp mode), an illuminated check engine light, overheating warnings on the dashboard, and possible engine performance issues.
3. What causes the P117A code on a Ford?
Common causes include low engine oil level, degraded oil quality, a faulty oil temperature sensor, cooling system issues, or excessive engine strain.
4. Can I drive my Ford with the P117A code active?
Driving with this code is not recommended, as it indicates potential overheating that can lead to severe engine damage if not addressed promptly.
5. How do I fix the P117A code on my Ford?
Check and top off engine oil if necessary, replace oil with the correct grade if it’s degraded, inspect the oil temperature sensor, and ensure the cooling system is functioning properly.
6. Can a faulty oil temperature sensor trigger the P117A code?
Yes, a malfunctioning oil temperature sensor can send incorrect readings to the engine control module, causing the P117A code to appear.
7. Does the P117A code always mean the engine is overheating?
Not always. It could be a false reading from a faulty sensor or a minor issue like low oil level, but it should still be investigated immediately.
8. How much does it cost to repair the P117A code on a Ford?
Repair costs vary, but replacing an oil temperature sensor may cost $100-$300, while addressing cooling system or oil quality issues could cost more depending on the severity.
9. Will clearing the P117A code fix the problem?
Clearing the code may turn off the warning temporarily, but if the underlying issue isn’t resolved, the code will likely return.
10. How can I prevent the P117A code from occurring again?
Regularly check and maintain proper engine oil levels, use the manufacturer-recommended oil grade, perform routine oil changes, and ensure the cooling system is in good condition.
