Question about 2002 Toyota Sequoia

2 Answers

Lights dim at stop and brighten on go

The other day I went to start my 02 Sequoia after it sat in the cold for two days and it was dead. I had to use my wife's car to jump it off. I went and had the battery tested and it tested good. I haven't had to jump it off since; however now when I stop at a traffic light if my heat is on high the lights dim. They brighten back up when I go. If my heat isn't on high then it idles normal. Any suggestions?

Check/clean battery ground connection[-] check alternator belt tension/condition and alternator wire connections.If you have a volt meter,check voltage at battery--with engine off-12 volts With engine running- 14 volts if alternator is good.

Testimonial: "I tested with volt meter and battery was at 12 volts without engine running and 14 volts with engine running. I went ahead a replace the battery and it fixed the problem. Battery was 5 years old must have had a dead cell."

I think the battery is shot

Is it over 5 years old replace it
then test the alternator output

Doubt the alterntor is bad the battery
won't hold a charge that is why your
lights are so dim,too much resistance
in battery cells

SOURCE: Toyota 02 is stalling, won't idle

Check the voltage of battery with voltmeter.. It is sometimes possible that if voltage of battery drops and jump start is needed, your computer will only charge to the last voltage that was recognized which would be when jumped...Try and charge the battery if possible I would actually suggest that you have your battery tested at local auto parts store and if it is presumed in good condition ,let them charge for you to max capacity . If battery has been tested and labeled as no good replace if necessary... Oh, and first thing you should do is make sure your positive and negative battery connections are clean and tight...if this didnt fix problem please give more info on what was found when advice above was followed...Good Luck!!!!

SOURCE: Dim dashboard lights and problem starting

Could be a loose or dirty battery connection, poor battery, or alternator. Check all the cables and connections to your starter. Clean your battery posts. Have your alternator and battery checked. It sounds like you are either running off just the battery or just the alternator. One of them is not right.

Check your brake pads first,as they have a wear warning clip on them.so if you hear a loud screaming noise.Then its quite possible they have worn causing ur warning lights to come on.And i would get anouther quote as that is quite dear for a pump replacement.If it is the pump.good luck pippall!!

you mentioned it sat in the cold for a few days if your fuel lvl is low it possibly could have froze up depending on your quality of fuel lower t is more chance of freezing up. maybe some drygas might help and recharge your battery back up.the rapid clicking is probly the battery drained and the solenoid clicking.

P0230....Fuel Pump Primary Circuit


P0725....Engine Speed Input Circuit

Here are the codes but i have no idea what could be causing the problem ,Perhaps the dead battery has done something to the ECU ,i would check the fuel pump feed out but first i would charge the battery for at least two days on trickle charge so the engine will crank ok as if the battery is too low this could cause problems although it should start with a jump and charge itself up but if the battery is too low it will not charge as a alternator needs power to produce a charge unlike a dynamo
