Question about 2002 Toyota Camry

1 Answer

2002 Toyota Camry 4 Cyl. I replaced the throttle body and then I unplugged the battery to reset the car. Now the car will stay idle but it will not accelerate. You can put the car in drive and reverse

Could my issue be a blown fuse under the hood or maybe the O2 sensor. I checked all my fluids they are good. Or is there something like a line or hose that I need to bleed to release are from the radiator or the accelerator line.

    I had an issue of the car not idle it would die unless you keep your foot on the accelerator now after replacing the throttle body it will not accelerate

    i think you should compare both of the throttle bodies for the readings with an ohm meter there are 4 leads on throttle posision sensor ,1 white with a blak line that is negative 1 lead of ohm meter to that pin and compare the other 2 sensors is it a new or used throttle body

SOURCE: 2003 Toyota Camry - Both Brake lights not working

Lok in the trunk on the left side, behind the carpet for a small plastic box with a bunch of wires going to it. Look to see if there is brake light powe coming in with the pedal depressed. If so, and no power is coming out, you need to order and replace the "taillamp failure sensor".

Firstly, ensure you have the required 'mixture' of coolant/water (must have required coolant).

Second, I would recommend you re-test all the cooling system sensors again (make sure they're within specifications), in case a new one is faulty.

Third, ensure the new thermostat was of the correct temp setting (they all differ), so that it opens at the required time. Most cooling systems operate within 90 - 100degC.

Fourth, make sure the radiator (and associated hoses) aren't blocked.

If your temp gauge is reading higher than normal, but NOT in the danger zone...then this can be considered normal (especially if you've replaced with new components) and nothing to be concerned about.

However, if the temp gauge IS in the danger zone....then this suggests the coolant is not flowing through the cooling system properly.

If all above components test ok, then it's possible your water pump may not be pumping enough volume.

i would not just go buy a tps on a guess
first check to see if you can bring the throttle up by hand at the motor where the throttle cable connects to the throttle body it may be a cable that broke

How to clean the throttle body and the idle air control valve

I typically remove them to clean but they can be cleaned on the car. Get throttle body cleaner from the store and spray all over. Manually open the butterfly valve and wipe after. I would take the idle air control vavle off to clean it.

After replacing the ALT 100A fuse in my 2002 Solara the idling is so low the car won't stay on unless I give it gas; it turns off at any full stop I come to. Any ideas what could be causing this?

Your throttle body has built up gunk in it. When the power was lost from the blown fuse, the learned values in the ecu for idle were lost. After this the default values are used, which are too low for stable idle when there the throttle body is dirty.

Remove the intake hose from the throttle body and clean the inside of the throttle body with a rag wetted with throttle body cleaner or non-chrlorinated brake parts cleaner. Be sure to open the throttle plate to get it totally clean.
Your idle will return to normal afterwards.

Idle to low

The idle is electronic, possible causes of this could be the idle air control valve, mass air flow sensor, and air hose from filter. You can verify if there are any leaks in your filter housing with a visual inspection, you can also remove the mass air flow sensor very easily and see if it is clogged with dirt.

Changed battery and now Camry will not idle.

Was it idling before you changed the battery? If you were to clean out the throat of the aluminum inlet manifold just behind the throttle body with a parts cleaner product that is safe for plastics (sensors) the car will idle.
The engine features a intake valve cover vent that goes back into the front of the throttle body. After time, the vent tube deposits a lot of oil and gunk in the throttle body assembly and just behind it into the intake manifold.

2002 toyota camery will not idle. after i replaced air filter, but it returned by itself. that's been about 5,000 miles ago, now it's back. also, i had the battery checked also and they same it was running...

This is ironic. I am on hear searching because the same thing happen to me today. replaced the battery and was having the smae idle issues. After a few hours of investigating and looking for air leaks we ended up with the intake into the throttle body housing loose and found alot of build up in the throttle body housing. Cleaned it out with carb spray and problem seems to have gone away for now. Not sure if this helps but this is where I am so far. Also check engine light was on and the tech erased it after cleaning and it has not come back on. Code was for mass air flow sensor and I originally tried a new one and it didn't change anything until I cleaned the carbon build up in the throttle body housing.

Replaced the battery in 2002 camry now it won't idle

When you replace battery in 2002 Camry ECM tries to reset to factory levels. The reason it will not idle is that the throttle body is dirty and ECM thinks it should be new!! Clean throttle body with cleaner that is safe for tbs and this will fix your idle problem.

Most likely a failed "IAC"; Idle AIr Control valve; located on the side of the throttle body.
