P0700 - Transmission Control System Malfunction, this is a transmission or PCM issue and needs further diagnosis with other test gear.

The P1684 code simply means that the battery has been disconneted within the last 50 engine starts.

Hi, I know from my past experiances the spark plug wires at the boot ends than slide onto the sparkplugs usually over time short out due to the metal tubes that protect the sparkplugs from heat kind of ark across from the metal tube through the plug boot causing an error code. Sometimes in the dark you can actually see them arking at the tube on the engine, and also hear a crackling noise. As to the code for the O2 sensor that's a normal wear and tear item that may need replaced. As all vehicle age over time electrical connections, and things have issues develop and cause havick with sensors and computers in these vehicles too.


As with the 441 code and then the other code for the O2 sensor showing up may mean both O2 sensors are going bad if your system has 2 sensors in the exhaust, usually one before the cat converter and one behind it. A lot of this also is due to what gasoline you use in the vehicle over time. Lower octane gas may be what is causing things to act up.

What could PO 302, PO 300, PO 105, PO106, PO 110,PO 115& PO 120 CODES Mean on a Toyota Camry 2000 model sedan car?


what engine, what size. that is first question.
misfire, map ,maf, iat, ect,tps and cat fail and low coolant temps.
very odd mix there. did you pull connections, key on???????

it means they all fail a test.
DIY? or just curious?

login to alldata.com
the question is , which is the most important.
all are cept 420, (last that, and bet goes way. later.)

reset the ECU, and see which come back.?
check all fuses.
then post codes that repeat, after fuse checks.

does the engine get fully hot running, 180F minimum?

Check engine light on, code # p1676 and PO 113


I don't show a code 113 for a Buick, but the code means the signal from the air temp sensor is high, which means the air temp is below zero or the sensor is faulty, or a problem with the wiring to the sensor.
Code 1676 is a problem with the canister purge solenoid which is how the computer vents the fuel tank. Could also be a problem with the vent for the tank.

Engine light on


You need to read the computer fault code to determine why. Take the car to any auto parts store (O'Reilly, Autozone, Napa, etc.). They will read it for you for free. They will give you a code that starts with PO something. Ex: PO435, PO317, etc. The code can then be translated to what is wrong with your Camry. It only take a copule minutes to read the code. They should also have the chart that tells you what the PO code means (what's wrong).

Went to TirePro to check engine light which is on. they ran diag and got 2 codes: one was po-700 something about the tranny isn't functioning right? Seems fine to me...what could be wrong?


P0700 means Transmission Control System Malfunction (a very general transmission failure code) I wouldnt be able to determine any thing from this code. maybe just a loose plug connector. Is the engine light staying on??? Cheers Ben

My engine light went on and ,I got codes Po 732 and Po 733 ? please advise what this means.


Transmission related. if shifting o.k. try erasing & see if they come back, if they do, get transmission checked . Better to check sooner than later on a transmission related problem, otherwise could cost big $. Don't be afraid of second opinion if not happy with first diagnosis.
