Check engine lt. came on...all fluid levels ok 2004 toyota tacoma v6 auto 4wd...61000 miles seems fine driving truck owned it since new not sure if the check engine lt is something i should be concerned...


The information below was complied by me, it explains what causes the check engine light to come on and the process of finding the cause.

When the Check Engine light (or Service Engine Soon) is turned on, the systems computer control unit (called the PCM) has sensed a fault in the electronic controls of the engine and/or the emission system. When this happens you will seldom feel the car engine run any different. There are about 200 possible system faults (the gas cap is just one of them) that turn the Check Engine light on, to know what has developed a problem you must have the system tested, this is called an OBD2 fault code test, Kragen/Oriley and Autozone parts stores (USA only) do this testing for free.

1999 1500 ls abs and brake light on at same time then off just sometime


WHEN YOU SEE BOTH LIGHTS AT THE SAME TIME YOU ARE HAVING BRAKE FAILURE EITHER MASTER CYLINDER FAILING OR ABS BRAKE MODULATOR FAILING.CHECK BRAKE FLUID LEVEL IN BRAKE MASTERCYLINDER. IF BRAKE FLUID LEVEL OKAY. I HAVE SEEN CASES WHERE ALTERNATOR FAILING CAUSING BATTERY VOLTS TO DROP AT 11.8 VOLTS CHECK BATTERY VOLTS AT BATTERY WHILE ENGINE RUNNING SHOULD BE 13.5 TO 14.5 VOLTS AT BATTERY WITH ENGINE RUNNING.IF BATTERY POWER IS OKAY.MORE LIKELY BRAKE MASTERCYLINDER AND ABS MODULATOR COULD BE FAILING. TAKE VECHICLE TO A GARAGE LET THEM CODE SCAN TO SEE WHAT CAUSING ABS AND BRAKE LIGHT TO COME ON.CODE SCANNING WILL SAVE YOU TIME AND MONEY.

What does it mean when the engine light comes on the dash of a 2000 Mercury Sable? All fluids are fine. Is this a Maintenance reminder? I have no owner's manual.


it could mean a million different things. the fluids will usualy be the last things to cause this. best i can say is either pull the fuse for the 'EFI' for 2 minutes or disconnect the battery for 2 minutes and it will clear it but if it comes back at all go to somewhere that will read codes for free like a parts store.

My 2001 Ford Focus was low on coolant which caused the multifunction warning light to illuminate. Coolant was added, but now the power supply to the engine is low and the charging system indicator is on. ...


Most "power supply to the engine is low and the charging system indicator is on" is an indication that your Alternator is failing. However it could also be a sign that the Belt is worn, stretched out or is slipping. Check you belt first to determine if you need a new belt.
If the Belt(s) are fine:
One way to determine if the Alternator is bad is start the vehicle and while the engine is running, remove the Negative Cable from the Battery. If the Engine dies, it is a bad alternator, and should be replaced.
The Battery starts the vehicle and run's other nominal operations. The Alternator actually runs the engine,
providing the fire/spark to it. If the Alternator is starting to fail, it will draw power from the Battery.
Let me know if this helped, or if you have any additional information, problems, or questions. Feel free to contact me at FixYa.com!
p.s. When you added the Radiator Fluid, did any spill onto the Belts or onto the Alternator? Radiator Fluid onto the Belt could have caused it to slip, causing these illuminations of the warning lights. It could also kill an alternator pretty quickly.

1995 Nissan Sentra, The engine light and brake


You could have faulty altenator or short causing the battery to drain. The engine light usually comes on when anything electrical or sensor wise is faulty. Brake light will come on if, low brake fluid, e-brake handle is up.

Steering hard /loosing pwer at 40-55mph


Take the car in for a new serpentine belt and tensioner right away before you destroy the engine. The alternator, power steering pump and waterpump are not turning right now because the belt has come off. The battery will die soon because it is not charging, and the engine will overheat and perform it's own little rendition of the china syndrome. When the red warning lights in the dash come on, it generally means; park it unless you're being shot at.

Check engine light came on don't know why


easy fix first , check the gas cap ,is it on tight?
disconnect positive on battery for a few minutes , then reconnect and restart your car . by doing this your resetting your computer(ecm) and if it was gas cap the light will go off. also look in your manual for emissions sensors , locate them and make sure they are all connected . also your oxygen sensor could be bad and needing to be replaced. also your oil , coolant , brake fluid , power steering fluids could be low . if not ,,,,,,,,, SALE IT !!! NO , NO , JUST KIDDING.... you should be fine
