The only way to reset the light is to put the system in relearn mode. First, make sure all the tire pressures are even set and to specifications. You may need to hook up a battery charger on low first...

Hi there. The EPC (Electronic Power Control) light is just a way to tell you that there is a problem with the drive by wire system. The issue could be the throttle pedal position sensor not registering to the computer...

Noise of that type is due to a failed or failing bearing in one of the pulleys or accessories (e.g., alternator, water pump, A/C compressor) that is driven by the serpentine belt, the belt is not properly tensioned, or the...

The red lightning bolt indicates that there is a problem wit the electronic throttle control unit. This may be for a specific reason or may be due to a slight glitch. Try resetting the throttle control unit by doing the...

Hi there, thanks for writing in. It sounds like your car is experiencing misfires due to low fuel. Even though your tank reads 1/4 full, the fuel level sender may be incorrect. This could be compounded by the fact that...

Hi There, The engine oil light is driven by the oil pressure in the motor at any given time. When you first start the vehicle up, this light comes on as it does a system check and momentarily detects engine...

This is often a sign of low transmission fluid or a faulty transmission control solenoid. As you know, automatic transmissions use pressurized hydraulic fluid to change gears. Every time a gear change is required, the car's computer activates a transmission...

Hello. If you've already cleaned the sensors with soap and water then you probably won't need to clean them again with stronger chemicals. The ABS sensors function as magnetic type sensors, and only need to be clean and free of...

Hello. It sounds like your time delay in the control module is not working. It may also be a short in the switch but that is not as likely. The retained power relay may be failing or the control module...

Hello, thank you for writing in. The first thing you should do is test the battery, or just go ahead and jump start it. Chances are the battery has simply died. If the vehicle starts, you will want to drive...

Hi there. There could be two problems here. It is possible that your battery is bad and will not take a charge from your alternator while driving. In that case every time you shut your car off you will not...

What you are describing sounds like a problem with the rack and pinion gears. The rack and pinion gear set does two things: It converts the rotational motion of the steering wheel into the linear motion needed to turn the...

If the ABS wheel speed sensor was faulty, once the new hub/sensor is installed, and you drive the vehicle, the warning lights should go out. To determine what is going on, you can manually erase the trouble codes using an...

The “tire pressure sensor fault” message is an indication that there is a problem with the tire pressure monitoring system (TPMS). A tire pressure monitoring system is required for all motor vehicles manufactured after 2007. The pressurized air inside the...

The idle is going to be high at first until the computer relearns the idle again. Cleaning the throttle body allowed more air to enter the engine, and the computer is compensating by adding more fuel. The idle will relearn...

Hi there. This is typically due to the spare tire being installed and the brake system sensors not aligned due to the different size wheel and tire combo. I'd recommend getting the tire replaced or repaired, correctly installed and having...

The Cal message can appear on your driver information center (DIC). When the DIC displays this alert, it means that the DIC compass needs to be calibrated. If this alert is accompanied by three dashes, then your compass is not...

Hello - most likely, your hard starting is caused by a malfunctioning fuel pressure check valve, or fuel pressure regulator. The fuel system is supposed to hold a small amount of residual pressure in the system for faster starts. A...

First, let's make sure about some terminology before I proceed. I will assume the motor is actually turning over. If the car is trying to start, the motor has to be turning over or it is not trying to start....

The low oil level is something that certainly needs to be addressed. However, it is generally not a cause for the check engine light to come on. The check engine light comes on when an electrical / electronic issues in...

The most common cause of this type of problem is when the fuel filler neck's inner tube comes off of the neck itself. You will need to have the filler neck removed to check to see if the inner tube...

Check your tire pressure as low tire pressure will cause the warning light to illuminate. Using a tire pressure gauge, if you do find low pressure in one or more tires, add air but you should also consider the possibility...

As you may know, after cleaning or replacing the throttle body your car needs to go through a "re-learning" process to bring the idle back down. Try doing the following which should bring the idle back down to a normal...

Odds are you have a faulty signal/hazard flasher relay. Although the relay is an electrical component, the internals are basically mechanical. The relay does just what the name implies. It relays power and the signal from the signal switch to...

Hello. A no start condition can be caused by many things. If it is not cranking at all then that likely signifies an issue with the starting circuit. If the battery, starter, and alternator have tested good then the next...
