- Additional Testing Fees (if required): $50 – $100
Types of Diagnostic Tests
There are several types of diagnostic tests that may be performed:
- OBD-II Scan: This is the most common test, which reads error codes.
- Visual Inspection: Mechanics look for obvious issues like loose wires or damaged components.
- Emission Tests: These tests check if your vehicle meets environmental standards.
Repair Costs
Once diagnostics are complete, repairs can vary significantly based on the issue identified. Here’s a general overview of potential repair costs:
- Minor Repairs (e.g., loose gas cap): $20 – $50
- Sensor Replacement (e.g., O2 sensor): $150 – $300
