Sample SVP Light Vehicle Mechanic Practice Questions

Try these sample questions to review concepts for the SVP Light Vehicle Mechanic exam. Each question includes a detailed explanation. Start the interactive quiz above for the full 162+ question experience with AI tutoring.

1What is the primary function of a spark plug in a petrol engine?

A.To ignite the compressed air-fuel mixture.

B.To cool the combustion chamber between power strokes.

C.To lubricate the piston rings inside the cylinder bore.

D.To measure engine speed for the ignition module.

Explanation: The spark plug is a critical component of the ignition system. Its main role is to create an electrical spark that ignites the compressed air-fuel mixture within the cylinder, initiating the power stroke of the engine.

2A compression test shows two adjacent cylinders reading equally low while the other cylinders are normal. What is the most likely cause?

A.A head gasket failed between those two bores.

B.An overheated catalytic converter downstream.

C.A clogged exhaust manifold restricting flow.

D.A faulty fuel injector on each of those cylinders.

Explanation: Two neighbouring cylinders that are low by a similar amount point straight at the fire ring in the gasket between them. Combustion pressure crosses from one bore into the other instead of being held, so neither can build a normal reading. A single low cylinder would instead suggest worn rings or a leaking valve.

3Which component is responsible for filtering contaminants from the fuel before it reaches the injectors in a petrol engine?

A.Oil filter

B.Catalytic converter

C.Air filter

D.Fuel filter

Explanation: The fuel filter is specifically designed to remove dirt, rust, and other particles from the fuel. This prevents them from clogging fuel injectors or causing damage to the fuel pump, ensuring clean fuel delivery to the engine.

4During an engine timing belt replacement, what critical step must be performed to ensure correct engine operation?

A.Replacing the spark plugs simultaneously.

B.Aligning the camshaft and crankshaft timing marks.

C.Bleeding air from the brake system.

D.Refilling the engine oil to the correct level.

Explanation: Precise alignment of the camshaft and crankshaft timing marks is absolutely crucial during a timing belt replacement. Incorrect alignment will disrupt valve timing relative to piston movement, leading to severe engine damage or the engine not running at all.

5A petrol engine shows a long-term fuel trim of +22% at idle that falls to about +3% at 2,500 rpm. What is the most likely cause?

A.A restricted exhaust caused by a failing catalytic converter.

B.An unmetered air leak at the intake manifold gasket.

C.A leaking injector dripping fuel into the intake port.

D.A weak fuel pump that cannot hold rail pressure.

Explanation: A vacuum leak admits a roughly fixed volume of unmetered air. At idle the total airflow is small, so that leak is a large share of it, the oxygen sensor reads lean and the ECU commands a large positive trim. At 2,500 rpm the same leak is a small share of a much greater airflow, so the trim falls back towards zero. Positive trim that is large at idle and normal off idle is the classic signature of an intake air leak.

6What is the correct technique for lifting a heavy component such as a gearbox from the floor?

A.Bend the knees and keep the back straight.

B.Bend at the waist and keep the legs straight.

C.Twist while lifting to build up momentum.

D.Hold the load at arm's length while lifting.

Explanation: Safe manual handling means assessing the weight first, standing with the feet apart for balance, bending at the knees and hips rather than the spine, and keeping the back straight with the load held close to the body. Anything beyond a safe individual lift belongs on a transmission jack, a hoist or a second pair of hands.

7If an engine's oil pressure warning light illuminates during driving, what immediate action should the driver take?

A.Add more engine oil while the engine is running.

B.Pull over safely and shut off the engine immediately.

C.Continue driving to the nearest service station.

D.Accelerate to clear the warning light.

Explanation: The oil pressure warning light indicates a critical lack of lubrication, which can cause severe and irreversible engine damage very quickly. Shutting off the engine immediately is the only way to prevent further damage until the cause can be investigated.

8Which sensor is primarily responsible for measuring the amount of oxygen in the exhaust gases to help the ECU adjust the air-fuel mixture?

A.Engine Coolant Temperature (ECT) sensor

B.Manifold Absolute Pressure (MAP) sensor

C.Crankshaft Position (CKP) sensor

D.Oxygen sensor (O2 sensor)

Explanation: The oxygen sensor, often called the O2 sensor or lambda sensor, is crucial for monitoring the exhaust gases. It sends data to the ECU, which uses this information to constantly adjust the fuel injection to maintain an optimal air-fuel ratio for efficient combustion and reduced emissions.

9After replacing a head gasket, the mechanic must follow specific torque sequences and angles for cylinder head bolts. What is the main reason for this precise procedure?

A.To maximize fuel efficiency at highway cruising speed.

B.To clamp the gasket evenly and avoid warping.

C.To reduce exhaust emissions during engine warm-up.

D.To prevent spark plug fouling during long idling.

Explanation: The specific torque sequence and angle tightening (torque-to-yield) for cylinder head bolts are critical for distributing clamping force evenly across the head gasket. This prevents leaks, ensures a proper seal, and prevents the cylinder head from warping, which could lead to further damage.

10What is the purpose of the engine's cooling system?

A.To lubricate the crankshaft, camshaft and other moving parts.

B.To filter contaminants out of the engine oil.

C.To pressurize the fuel rail for the injectors.

D.To remove combustion heat and hold operating temperature.

Explanation: The cooling system's main role is to regulate engine temperature by carrying away excess heat produced during the combustion process. This prevents overheating and allows the engine to operate efficiently within its designed temperature range.
