"Check Engine" light on when I step on the brake
 

this is a weird one ........... the check engine light seems to go on when I press on the brake pedal. Sometime it would flicker.

I was wondering if their is a link between those two electrical connections (are they located near each other)?

There could be if we only knew what year and model we're dealing with.

Have a great day,

I would think (year and model aside) that the "brake pad wear" indicator is flickering, not the check engine light. If indeed, the CE light comes on when braking, then someone crossed some dash wiring somewhere! :confused:

The "brake pad wear" indicator is yellow, and the icon looks like a circle with dashes around the left and right circumference.

The brake pad sensors are attached to the pads and are designed to contact the disc when the pads reach a certain wear limit. That contact is ground, and it completes the circuit to set off the light on the dash. So you probably have around 2-5K of pad life left (depending on your driving habits).

Some cars have sensors all around, but most just have them on the fronts only. More than likely, it's time to get a new set of front pads.

my bad!
 

ooops, I guess I should have looked into the owner's manual first for this one.

G-Benz is right on the money, it is the brake pad wear sensor that is being triggered. I have not looked at my pads just yet but I'm pretty sure that this is the problem.

thanks everyone!
