- Loose or faulty gas cap
- Faulty oxygen sensor
- Clogged air filter
- Faulty spark plugs
- Low oil level
- Faulty catalytic converter
In this article, we’ll focus on the relationship between low oil levels and check engine lights.
How Does Low Oil Level Cause a Check Engine Light?
When the oil level in your vehicle’s engine is low, it can cause a range of problems that trigger a check engine light. Here are some of the ways low oil levels can cause a check engine light:
1. Oil Pressure Sensor Malfunction
The oil pressure sensor is responsible for monitoring the oil pressure in your engine. When the oil level is low, the sensor can malfunction, causing the check engine light to come on. (See Also: What Happens If Engine Oil Is Not Changed)
2. Engine Wear and Tear
Low oil levels can cause excessive wear and tear on your engine’s moving parts, leading to premature wear and tear. This can trigger a check engine light as the engine’s computer detects unusual wear patterns.
3. Engine Overheating
Low oil levels can cause your engine to overheat, which can trigger a check engine light. When the engine overheats, it can cause damage to the engine’s internal components, leading to costly repairs.
4. Fuel Efficiency Issues
Low oil levels can also affect your vehicle’s fuel efficiency, causing the check engine light to come on. When the engine is not properly lubricated, it can cause the engine to work harder, leading to decreased fuel efficiency.
How to Diagnose a Low Oil Level Causing a Check Engine Light
Diagnosing a low oil level causing a check engine light requires a combination of observation, testing, and troubleshooting. Here are some steps you can follow to diagnose the problem:
Step 1: Check the Oil Level
The first step in diagnosing a low oil level causing a check engine light is to check the oil level. You can do this by locating the oil dipstick under the hood of your vehicle and pulling it out. The oil level should be between the “MIN” and “MAX” marks on the dipstick.
Step 2: Check for Oil Leaks
If the oil level is low, you’ll need to check for oil leaks. Look for signs of oil leakage around the engine, such as oil spots on the ground or a puddle of oil under the vehicle. (See Also: Why Does An Engine Need Oil)
Step 3: Use a Scan Tool
