MTO Vehicle Maintenance & Inspection 2

Question 1

How often should you check your vehicle's engine oil level?

Accepted Answer

At every fuel fill-up or at least monthly

Answer

Checking oil at every fill-up or monthly helps catch leaks or burning oil before engine damage occurs.

Question 2

What does a vehicle's tire pressure monitoring system (TPMS) warning light indicate?

Accepted Answer

One or more tires are significantly under-inflated

Answer

The TPMS light illuminates when tire pressure drops 25% or more below the recommended PSI.

Question 3

Which component should be inspected if your vehicle pulls to one side while braking?

Accepted Answer

Brake calipers or pads

Answer

Uneven brake pad wear or a stuck caliper causes the vehicle to pull toward the side with more braking force.

Question 4

What is the purpose of the PCV (Positive Crankcase Ventilation) valve?

Accepted Answer

Recirculates harmful crankcase gases back into the intake

Answer

The PCV valve prevents pressure buildup and reduces emissions by routing crankcase gases to be burned in the engine.

Question 5

When should you replace your vehicle's cabin air filter?

Accepted Answer

Every 15,000–25,000 miles or per manufacturer recommendation

Answer

Cabin air filters trap dust and pollen for the HVAC system and typically need replacement every 15,000–25,000 miles.
