    The battery light flickers because the diode in the voltage regulator may be failing, or the voltage regulator circuitry is compromised. The voltage output may be correct, at times, but the detection circuit in the regulator allows the light to illuminate if the voltage drops below 8.5 volts. It looks like you have internal alternator issues, and that cannot be tested with the alternator on the car.

you have to understand that there is a leak in the system other than the gas cap for the evaporative system. The system needs to be professionally closed, and smoke introduced into to find the leak, and a through component check, eg.. purge valve vapor canister vent solenoid all functioning correctly

Hello. You can do this yourself.

You need to replace the Air-fuel sensor. I would strongly suggest that you purchase and install a Toyota sensor, however. The "aftermarket" sensors do not have the exact same voltage signals, and will not rectify the condition; the light will remain on. We see this quite a bit in our service dept.

We hope that this helps you out.

SOURCE: 87 toyota camry new battery wont keep charge,

Generally if charge light is on, alternator has a bad diode in it. This lets the charged battery lose its power by flowing in the reverse direction. It sounds as the alt., is either not connected right or is swtill bad

Did you have the computer reset after the part was changed? That is what you need to do. It may also take some time for the computer to relearn everything. Was it a bad maf sensor or a probem in th circuit itself? There is a difference. If it was just the sensor and you replaced it, then reset the computer and let it relearn. Make sure your charging fuse and relays are good as well as making sure the ground cables and battery cables have clean connnections and are tight.

I have an 2002 camry le. My car goes dead at a stop light or sometimes as soon as I switch it on. The idle will start going down but if I turn the ac on it will idle back up and stay on. When it starts...

check the output of your alternator it may be low ,and check the belt as it may be slipping .the fact that when you put on your AC shows the trouble is a slipping belt, do that first, then check the output of the alternator.

Charging system light on

The charging system in your vehicle is computer controlled ,checking for DTC'S - diagnostic trouble code's should alway's be the first step in the diagnostic process ,testing for B+ voltage at the wiring connections at the alternator would be the next step if no DTC'S are stored . The single heavy gage wire on the back should have Battery voltage , the wire's at the connector ,three out of the four should have B+ voltage an the # 3 wire is the control circuit from the ECM - engine control module . Four fuse's supply B+ voltage to these connections . 10 amp gauge #1 , 7.5 amp gauge #2 , 7.5 amp ALT-S an 120 amp ALT fuse. If any one of these is blown the alternator won't charge . If you know nothing of automotive electrical system testing ,your best bet would be to take your vehicle to a qualified repair shop.

My 2008 Camry was running fine, no warning lights on. Came out of the grocery store and it would not start, all the lights game on but it acted is if the battery was low. Got a jump start, drove two blocks...

It may be that the battery is bad where it won't take a charge from the alternator so it should be checked for that using test equipment, most autoparts stores like Autozone, Kragen, Advance Auto provide this service at no charge, since it's an 08 there is a chance that it may still be covered under the toyota factory which is 3yrs/36,000 miles for electrical parts.

Battery light indicator keeps coming on? stays on for few seconds sometimes a few minute. Flickers on and off while driving or turning steering wheel

two things to be checked, the battery and the alternator. These can be checked in many auto part stores free of charge. I suspect the battery is bad.

I have a 1999 Jeep Grand Cherokee Limited. I just replaced the battery about a month ago but lately I have had to jump it to get it started. Sometimes it will start than die. Other times it will act like...

Take it to an auto parts store that will do a diagnostic on the charging system (alternator) and also check that both battery cables are clean and snug at both ends. Sometimes battery cables will corrode inside the plastic insulation so have them checked with an ohm meter.

Battery light comes on when accelerating, alternator is ok

In fact the Alternator is on it's way out, I had Taurus that was doing the same thing. When the RPM's were over 3000 the light would flicker. What happens is, the slip rings wear and get out of round and when the RPM's get too high the brushes start to bounce causing the light to flicker. Keep in mind the alternator is spinning about 3 times the speed of the engine. Pick up an alternator it's just a matter of time, mine went about 6 months like that, try to keep the RPM's low.

How do I troubleshoot the charging system?

test battery and alternator battery may be loosing charge or alternator output enough to run vehicle but not enough to keep battery charged some auto stores such as auto zone/advanced auto can bench test both for free

Battery and brake lights flicker and headlights dim

Sounds like a low voltage problem, alternator not charging properly. When you press the gass the motor takes more juice from your battery to fire the spark plugs have you had your charging system tested (most auto parts places do it for free)? Either that or a loose wire causing the short. Check all grounds under the hood and make sure they all have a good contact

The battery light came on when I was idling at a red light. Do you think I need a new battery? Camry 2003 80000 mi

when the battery light comes on, it doesnt Usually mean your battery is bad. it tends to be the charging system. take your car to your local auto parts store and have them run a diagnostic on the charging. they tend to do it for free, and it only takes a couple of minutes.
usually this will happen if your alternator is going out, or the voltage regulator. however, there is a possibility that your battery is not holding the charge anymore, but their test will tell you that as well
