Common Questions
What does P0517 mean and how does it affect my car?
The P0517 code indicates a high voltage from the coolant temperature sensor, which can lead to incorrect engine temperature readings. This can cause poor engine performance and may result in overheating if not addressed quickly.
What are the most common causes of P0517 and how much does it cost to fix?
Common causes include a faulty coolant temperature sensor, damaged wiring, or a malfunctioning ECM. Repair costs can range from $100 for a sensor replacement to $1200 for ECM replacement.
Can I drive my car with P0517 or should I stop immediately?
While you may be able to drive your car for a short time, it is not recommended. Ignoring the P0517 code can lead to severe engine damage and should be addressed as soon as possible.
How can I diagnose P0517 myself using GeekOBD APP?
You can use the GeekOBD APP to scan your vehicle for trouble codes, view freeze-frame data, and monitor the coolant temperature sensor readings to identify if the sensor is functioning correctly.
What vehicles are most commonly affected by P0517?
The P0517 code is commonly found in vehicles like the 2008-2015 Ford F-150 and the 2010-2015 Chevrolet Silverado. Always check for any recalls or service bulletins related to this issue.
How can I prevent P0517 from happening again?
Regular maintenance, including inspecting wiring and connectors, can help prevent issues that lead to P0517. Keeping the cooling system in good condition is also critical.
What is P0517?
The P0517 diagnostic trouble code (DTC) indicates an issue with the engine's coolant temperature sensor circuit. This sensor is crucial for monitoring the engine's temperature and sending this information to the Engine Control Module (ECM). When the ECM detects a voltage that is higher than expected from the coolant temperature sensor, it triggers the P0517 code. This high voltage can result from various issues such as wiring problems, a faulty sensor, or issues with the ECM itself. In practical terms, when this code is triggered, it can lead to poor engine performance, decreased fuel efficiency, and even potential engine overheating if not addressed. Owners of vehicles, especially Ford and Chevrolet models produced between 2008 and 2015, should take this code seriously as it can lead to more significant engine problems over time if left unchecked. It’s essential to understand that ignoring this code can lead to reduced engine performance, higher emissions, and even engine damage, which can be costly to repair. Regular maintenance and timely diagnostics can prevent these issues and ensure that your vehicle runs smoothly.
System: P - Powertrain (Engine, Transmission, Emissions)
Symptoms
Common symptoms when P0517 is present:
- Check engine light stays on constantly, indicating a persistent issue that needs attention.
- Engine hesitates during acceleration, leading to a frustrating driving experience.
- Fuel economy decreased by 10-15%, causing you to spend more on gas than usual.
- The engine may run rough or misfire, impacting overall performance and drivability.
- Overheating engine, which can lead to severe damage if not resolved quickly.
Possible Causes
Most common causes of P0517 (ordered by frequency):
- Faulty coolant temperature sensor (approximately 40% likelihood) - This sensor may fail due to wear and tear, leading to inaccurate readings.
- Wiring issues (30% likelihood) - Damaged or corroded wiring can create short circuits that affect sensor readings.
- ECM malfunction (20% likelihood) - A failure in the engine control module can misinterpret sensor data and trigger the P0517 code.
- Thermostat issues (less common) - If the thermostat is stuck closed, it can cause engine overheating and lead to high voltage readings.
- Electrical shorts (rare but possible) - Rarely, issues in the vehicle's electrical system can cause unexpected voltage spikes.
