- Provides repair recommendations and estimated costs
- Shows related OBD-II diagnostic trouble codes

FAQs
Q: What does the check engine light mean on a Toyota?
A: The check engine light indicates the engine management system has detected a fault. Common causes include a loose gas cap, oxygen sensor failure, or catalytic converter issues.
Q: Is it safe to drive with the oil pressure light on?
A: No. If the oil pressure warning light comes on, stop the engine immediately. Driving with low oil pressure can cause severe engine damage.
Q: Why is my Toyota’s brake light on?
A: The brake warning light can indicate low brake fluid, worn brake pads, an ABS system fault, or that the parking brake is engaged.
Q: What should I do if my Toyota overheats?
A: Pull over safely, turn off the A/C and turn on the heater, and wait for the engine to cool before opening the hood. Check coolant level when safe.
Q: How much does it cost to fix a check engine light?
A: Costs vary widely from $100 for a simple sensor replacement to $1,500+ for catalytic converter replacement. A diagnostic scan is the first step.
