how do i check if a sensor is bad? ... ex. BRAKE sensor

JSM1284

What sensor do you need to test? And for what year and model?

mrchacon

Brake Sensor...

but how does it differ for others?

JSM1284

What brake sensor? ABS Brake sensor? Brake fluid level sensor? You have to be alot more specific.

mrchacon

well the BRAKE light on the dash is lit... i checked the brakes and they seem with plenty of pad left... i checked the fluid.. it was low... i refilled it to the full mark.. but the light is still lit... someone recommended that i check the sensor... so i suppose its the brake fluid sensor... or one that could cause the BRAKE light to be lit...

JSM1284

That would be the fluid sensor in the master cylinder resevoir. You may need to jiggle the cap a bit, sometimes the float gets stuck and doesn't turn the light off. What year is your ES?

mrchacon

98 es300 -- jiggle the cap itself or jiggle the entire resevoir?

mrchacon

bumping for jsm...! =)

Give the resevoir a few taps. Also, Check to make sure the parking brake is all the way released.

Oo, this will be helpful for me. The "BRAKE" light flashes on every time I corner

That happens when you're cornering on 2 wheels, eyezack.

I'm always on 4 haha. Never gone tripod or anything in my ES. It popped up recently too so I'm hoping what was suggested above will help. Though now it hasn't popped on for 2 days
