TECHNICAL CHECK
Sensor and ECU Diagnostics
A fault code does not automatically mean “replace this part.” Trigger conditions, live data, power/ground integrity and physical symptoms are assessed together.
What is reviewed?
- Confirm compatible diagnostic communication
- Read current and stored fault codes
- Review conditions associated with the fault
- Check relevant sensor power, ground and signal circuits
- Recheck codes and operation after repair
Model-specific limit: A diagnostic code is not a direct parts-replacement instruction; it must be verified through testing and the manufacturer diagnostic process.
