This summary uses the existing diagnostic information shown in full below.
The car's computer thinks the sensor that checks how hot the engine is has a problem because it's showing a very high reading.
The P017D code indicates that the engine control module (ECM) has detected a high voltage signal from the Cylinder Head Temperature (CHT) Sensor A, which could mean the sensor is reading a temperature that is too high.
The Cylinder Head Temperature Sensor A is responsible for monitoring the temperature of the engine's cylinder head. It sends this data to the ECM to help regulate engine performance and emissions. A 'Circuit High' code suggests that the sensor is reporting a temperature reading that is higher than expected, which could be due to a wiring issue, a faulty sensor, or an actual overheating condition.

• Regularly check and maintain engine cooling system.
• Inspect wiring and connectors periodically.
• Ensure proper engine maintenance and servicing.
Sensor Issue
• Do not ignore the Check Engine Light.
• Avoid driving if the engine is overheating.
• Seek professional help if unsure about repairs.
Check with the vehicle manufacturer as some sensors may be covered under warranty.
This code has been associated with issues in vehicles with high mileage or poor maintenance history.
High – Address promptly to avoid potential engine damage.
Ignoring this code can lead to engine damage and increased emissions, which may not comply with local regulations.
• Engine at operating temperature
• Vehicle stationary or on a test drive
The Cylinder Head Temperature Sensor is typically located on the cylinder head of the engine, often near the intake manifold.
Q: Can I drive with a P017D code?
A: It's not recommended to drive with this code as it may indicate engine overheating, which can cause severe damage.
Q: How do I know if my engine is overheating?
A: Signs of overheating include a high temperature gauge reading, steam from the engine, or a burning smell.
