24 is an air intake temperature circuit fault
31 is a fault in the MAP sensor circuit or air flow meter circuit.

It may be that there is a short or corrosion in the wiring connections to that area of the engine intake tract. Disconnect and reconnect these a few times to see if the fault is cleared.

Note: to clear trouble codes you will have to remove the EFI main fuse for 30 sec. See here p 299

http://www.turboninjas.com/camry/eg1.pdf

The output of these 2 codes simultaneously points to the ENGINE coolant temp sensor ground circuit being broken somewhere (E2 connection). See above link p356. Using this info you can also test the sensors in the air intake.

P-0102 and P-0113 are mass air flow and intake air temp codes, the P-0136 is an Oxygen sensor code. Before you do anything, check for debris in the Mass Air Flow Sensor, it's small black box with electrical wiring connector that is screwed into the intake air tube, between the air box and the intake manifold. Undo the screws, remove the sensor, and, with a flashlight, and look down inside it for debeis, or broken wires inside it. If it's dirty, it could throw a P-0136...Comment back on what you find; hope this helps, and thanks for choosing FixYa!

SOURCE: 1993 Toyota Camry V6 Timing Settings

Get a T belt from toyota. It has 3 white lines on it and and arrow mark. 2 lines are solid and one is broken. Put the arrow facing away from the engine. The cam gears have a dot punched into them near a certain tooth. This is where the solid white lines will line up with. The crank gear will have a dot also. It will line up at 90 degrees from the top, towards the front of the car. This is where the broken line will match up with. With the belt installed with all lines on their proper dots and arrow away from the engine, you valve timming is correct.
Of course you need to remove and compress the tensioner also. I assume you know this already since you didn't ask.

I have a 1993 Toyota Camry xle. I changed the air filter and now the car starts but won't idle. Just sputters to off when I let off the gas. What happened?


Either something got unplugged, or the hose between the mass air flow meter and the throttle body is loose causing an air leak.

Of course the V6 has this sensor. It is vital to get the right fuel-air mixture.
Depending on your location, it may be mounted in the rear side of the air cleaner housing or in the mass air flow meter as here, p451, with test procedures

My 89 Toyota pickup idles too fast in cold weather


I would have a look at your coolant sensor, if it's reading the wrong temperature, it will cause a idle problem. If you can, get a scanner on it to verify it's operation.

Is a airflow meter for v6 1993 camry needed? I am trying to put an cold air intake, but im not sure if i can remove the airflow meter or not. also any help on intalling a cold air intake on the car would...


You MUST have the air flow meter installed on your vehicle. The car will not run if you remove it. The Air Flow Meter measures the amount of air coming into the engine, and also the air temperature. This information is sent to the fuel injection computer, to determine the proper fuel to be injected. In reality, cars with "air-flow meters" do not really "benefit" from a cold air intake, due to the inherent restriction that the air flow meter causes, as it measures the air.
In short, I would not install the intake, you won't see much benefit. The graciousness of a FixYa rating for my assistance would be greatly appreciated..
