There are a few reasons why your car’s EPC light may come on. It could be something as simple as a loose gas cap, or it could indicate a more serious problem with your engine. Unfortunately, the light does not feature the specific issue, and many individuals do not know what to do in such a situation.
In this article, I will discuss some possible reasons behind this problem and a few ways to fix it.

Can Low Oil Levels Cause EPC to Light Up?
Low oil levels can cause EPC to light up. This is because the engine needs oil to lubricate itself and when there isn’t enough oil, it can cause friction, which in turn can cause the EPC light to come on. If you’re low on oil, make sure to top it off as soon as possible. Driving with low oil levels can cause long-term damage to your engine.

What is an EPC Light?
The EPC indicates an issue with the Electronic Power Control Systems on board. These problems are critical because the power of the system is very important for stability control, cruise control, and other engine management functions.
The Most Important Reasons for EPC Light Illumination
Recognizing a problem is the initial step toward settling it. To fix the problem, you need to first identify the source of the problem, which can be anywhere on the vehicle.
There are several reasons why the EPC light within the vehicle may turn on:
- Failed Throttle Body
- Broken ABS Ring
- The Issue with The Motor Inside
- Damaged Steering Wheel Sensor
- Broken Engine Sensor
- Defective ABS Sensor
- A Broken Brake Pressure Sensor
- Issues With The Abs Sensor Wiring
- Failed Brake Pedal Switch
- Power Steering Failure
Failed Throttle Body
If you squeeze the choke rapidly, you may witness an awfully low level of inactivity or slow down. This can be due to how the choke body plate might open and shut excessively fast.
Broken ABS Ring
The ABS ring is located at the bottom of the car and opened to plenty of fragments. In the end, it may need to be repaired or replaced. The back ABS rings may suffer more than the front ones.
Problem Inside the Motor
Assuming that the problem is in the internal motor, it may cause some problems, such as the vehicle’s driving or strange hustle and bustle, oil stains, and odors. It may also consume more gas.
Getting this fixed should be your primary goal, as replacing a motor can be very expensive.
Damaged Steering Wheel Sensor
A damaged control wheel sensor is effectively recognizable. Assuming the steering sensor is harmed, the pointers will not be adjusted to the data you require to control the vehicle. The steering wheel might feel like it is free, and it will not be in your control. This is risky and could be a disaster, especially at higher speeds.
Broken Engine Sensor
A damaged engine sensor is one of the most common problems that can occur with your car. This sensor is responsible for sending information to the computer about the engine’s performance. If it becomes damaged, it can cause the engine to run erratically or even stall. In some cases, it can also cause the EPC light to come on.
ABS Sensor Defect
To decide if the issue is with the ABS sensor, check regardless of whether the ABS light is turned on. If the sensor is broken, you may notice a siphoning impact in the brake pedal, and keep in mind that when you press the brake, the vehicle completely releases the control wheel. This makes the vehicle pretty vulnerable to accidents while being driven on wet roads.
Faulty Brake Pressure Sensor
The brake pressure sensor is a small, important component in your car’s braking system. If it starts to fail, it can cause big problems. One of the most common symptoms of a failing brake pressure sensor is erratic or pulsing brake pedal behavior. If you press the brake and the pedal feels like it’s pulsing or vibrating, it’s likely that the sensor is starting to fail.
If you notice these symptoms, it’s important to have the brake pressure sensor checked out as soon as possible. A failing sensor can cause your car’s braking system to fail, which can be extremely dangerous.
Issues with the ABS Sensor Wiring
One of the most common issues with the ABS sensor wiring is when the wires become frayed or damaged. This can happen over time due to exposure to the elements or simply from wear and tear. If your wires are damaged, it’s important to have them replaced as soon as possible to avoid any potential problems with your ABS system.
Brake Pedal Switch Failure
Brake pedal switch failure is usually caused by a simple electrical problem, but it can also be caused by a more serious problem with the braking system.
One of the most common symptoms of brake pedal switch failure is the brake lights staying on all the time, even when the brakes are not being applied.
Other symptoms of brake pedal switch failure can include the brakes not working properly, or the brake pedal feeling “spongy” or soft when you press it.
If you suspect that your brake pedal switch may be failing, it’s important to have it checked out by a qualified mechanic as soon as possible.
Power Steering Failure
If your power steering fails, it will be very difficult to steer your vehicle. You may hear a whining noise when you turn the steering wheel. This is usually caused by a loss of hydraulic pressure in the system. If this happens, you should pull over and turn off the engine.
Once the engine is off, you will need to pump the steering wheel to build up enough pressure to steer. Once you have built up enough pressure, you can turn the engine back on and continue driving.
What Are Some Other Warnings Associated With Engine Oil?
The EPC light activates after sensing a malfunction with the engine and a few other associated components. To prevent further damage, the ECU limits accelerator usage.
Some other warning lights may also illuminate because the EPC monitors multiple other systems.
- The ‘Check Engine’ Light may illuminate since the engine is not fully operational.
- The ECU may also turn off the Cruise Control and Stability Control Systems, causing their corresponding dashboard lights to illuminate.
- Warnings from the ABS and steering wheel sensors are possible.
How To Fix EPC Light Up Due To Oil Levels?
If you check the oil ruler and the oil level is lower than the safe level, you need to fill it up. In most cases, the bottom marking on the oil ruler indicates that the engine is low. However, if you are at your oil change mileage or beyond, it is necessary to have your oil changed.
After long-term use, due to small leaks or general wear, your oil level may begin to decline. If your vehicle is older, the chance of this situation is higher, and sometimes it will cause multiple leaks.
Risks if EPC Light is ignored
- Whenever the EPC light is on, it suggests there may be a couple of limited options in your automobile. Since the EPC is associated with the steering and braking system, it may cause motor damage and fatal accidents due to limited braking or directing capabilities.
- If you keep on overlooking the advance notice light, you risk major problems such as wearing out of motor parts costly repairs, and eventually a new engine. Don’t wait until it’s too late
