This code means that the car's computer is having trouble talking to the engine about how fast it should run when the car is not moving.
The P17DA code is triggered when there is a problem with the communication between the engine control module (ECM) and the idle speed control system via the CAN (Controller Area Network) bus.
The P17DA code indicates that the ECM has detected an issue with the CAN signal responsible for communicating the desired idle speed to the engine. This could be due to a faulty signal, wiring issues, or a problem with the ECM itself.

Engine Performance
• Avoid driving with a persistent Check Engine Light
• Seek professional diagnosis if unsure
• Regularly check vehicle for updates or recalls
Check with your vehicle manufacturer for warranty coverage on ECM issues.
The P17DA code has been associated with CAN communication issues in various vehicle models, often requiring ECM updates or replacements.
Moderate – It is advisable to address this issue soon to prevent potential drivability problems.
Driving with a malfunctioning idle control system can lead to unsafe driving conditions. Always ensure your vehicle is in proper working order.
• Engine at normal operating temperature
• Vehicle in park or neutral
The ECM is usually located in the engine bay or under the dashboard, while the CAN bus wiring runs throughout the vehicle.
Q: Can I drive my car with a P17DA code?
A: It's possible, but not recommended. The vehicle may not idle properly, which could lead to stalling or poor performance.
Q: How can I prevent a P17DA code?
A: Regular maintenance and ensuring all electrical connections are secure can help prevent this code.
