The problem will be in the alternator,it is not charging enough,and it is on it`s way out,If this was at all helpful,please rate,the voltage at the battery should read with a volt meter,13.65 volts to 14.25 volts with the headlights are turned on,and ac on high blower motor.If it is not in this range,replace the alternator.

Trying to clean the MAP sensor will damage it. Install a New Air filter and The Fuel filter, then replace the MAP sensor. Do not touch, or spray(compressed air or solvent) on the element when installing it. Have all of the OBD II Stored codes Deleted. Add a can of B&G 44K fuel additive to a full tank of fuel. The B&G is the best on the market, do not substitute. It is only available Through dealerships (Toyota). It will condition fuel pump and injectors. The ECU in your car is very dependable and rarely needs replacing. Always Replace cheapest parts first. Test drive the car and Then recheck The OBD II for new faults. The dimming of your lights before shut down was due to RPM of the engine dropping below 750 RPMs. Alternator will not produce voltage below 750 Rpms. 30 Amps at 14 Volts is required to run the engine.

You shoulld expect more than 12.8 volts from the alternator up to nearly 14 volts when charging a low battery. The battery can only show the amount of voltage your alternator is sending to it after being used for a while. I would suggest that you have the battery tested & recharged completely, your voltage will be above 12 volts and if it returns to below that , you will know your alternator is not charging. Also, if you test the output of the alternator and see it is below 12 volts after the battery is fully charged at 12+ volts you will have confimed the problem also.

good luck.

Labors when starting. When turned over all lights and gauges go black, then back to normal


First, have the battery load tested (charge, put a 200 amp load on it and read voltage..(15-20 seconds only) .should not drop below 9.5 volts) After verifying that battery is good, put a volt meter across the battery terminals when installed. If cranking volts drops below 9.5 your starter is bad. Before testing anything on car, make sure all terminals and wire lead connections are clean and secure.

Charging system


When the new alternator was installed did you perform a charging test to ensure it works properly. If it's not the alternator may overcharge the battery causing corrosion to the posts and possible cracking of the battery case. If you don't have the tester at home most auto parts stores can connect theirs and it usually is free.

Good luck to you

Instrument panel went dead


Checked Every fuse in the fuse box (no small task).This includes #4 - Power point Instrument Panel, #14 - Day time running lamps (auto lamps doesn't work nor does auto lock), #27 - ignition switch run feed, #35 - Instrument Cluster, #41 - Instrument Cluster, #42 - Delayed Accessory, #45 - Ignition switch run/start feed, #102 - Door locks body security module, #103 - Ignition switch, #110 - Ignition switch, & #116 - Ignition switch. But I also check all other ones as well, they all register OK. AC panel & radio work. Turn signals work. Mileage does not work, trip computer does. So, basically, everything works except auto head-lights, auto locks, and the dash cluster (no MPH, RPM, mileage display, Fuel, Temp, Tran Temp, and Oil Pressure).

Battery test proper voltage, new alternator test normal to low voltage,have trouble starting at times. while driving amp gauge shows varying readings of 14 to 10


If you test battery with a load test it will probably fail. Battery is bad. Also have alternator tested. Go to any parts store, even walmart they all test for free. I would put my money on bad battery. Cells getting weak.
