93 toyota camry check engine light is flashing 2,4
Stuck paper clip in diagnostic slots as suggested and got 2 flashes followed by 4. Also, overdrive indicator light is flashing. Having trouble w/ o/drive in cold temps until tranny warms up on highway, then she'll shift. What's up? Can I fix? thx, smpdog ps: it's a 4 banger, won't let me put that in product section below text box
I bought a used Toyota 4-Runner and the check engine light is on...I took it to Advance Auto and they said they are not able to run a code check on models older than a 1996 any suggestions?

on gm vehicles that are 1993 and older with an ecm,it is possible to diagnose check engine light using a paper clip.just below driver is a black box that has either 6 or 12 slots.put paper cilp one end in slots a and 1in slot b then watch check engine light.count flashes ,should flash once then pause then it will flash 2 times indicating a code 12 it will flash thic code thee times indicating computer is working after the code 12 it will flash the trouble codes.
It means there is a detected problem in engine control that has set a fault code.
The easiest way to deal with this is take it to a repair shop/dealership with the proper scanning equipment and they can extract the faulty code and perform the repair.
If you would like to try it yourself, if you can understand the following,m then get the codes and report back.
\Insert a jumper wire or paperclip between ports T1 and E1 in the diagnostic connector located underhood. ONLY those 2 ports.
When inserted with key on, the check engine light should begin flashing. If it does, it is working. If it doesnt, then you have the wrong pins or the system isnt in idle ground/code pulling condition. The throttle must be closed and the idle tracking switch showing CLOSED before the computer will start flashing codes.
If what I have just said makes NO SENSE, then you really should seek the help of an experienced technician. If what I just said gets you weird flashes, count them. when you 1st turn the key on, it will flash a nimber of times, then at some point a pause, then more flashes, then a longer pause and more flashes. The short flashes are to seperate digits, the long flashes are to seperate codes if there are more than 1. So for example --- pause -- long pause ---- pause ---- would be a code 32 (3 pause 2) and a 44 (4 pause 4).
If you can use that info, post results and maybe I can help. If not, having it checked by a professional may be a better choice.
I would check for fuel,(pressure and injector pulse), spark, and compression, before checking any codes. Lack of any of these basics can result in codes, and then you waste alot of time chasing a symptom, instead of the actual problem.If more people followed basic diagnostics, which always come back to these three basics, rather than chasing codes first,they would find no starts much more quickly.
You have the On Board Diagnostic 1 system which applied to most vehicles through 1995. In 1996, the OBD 2 system took effect.
So on your Toyota, the way to read out your codes is with the check engine light itself. When you make a connection with a "jumper" wire and turn the ignition key to on (but not start), the check engine light will flash a series of codes. The connection to make is in a small black box under the hood called the "test connector". The box will be labeled "diagnostic" or "diag". The cover flips open and on the inside of the cover there is a chart showing what each test terminal is for. Using a small jumper wire or a paper clip, connect the two terminals TE1 and E1. Now grab paper and pen and sit in the driver's seat and turn the key to on (not start). The check engine light will start flashing the code(s). The two digit code(s) will repeat until you turn off the key.
A sample code of "35" will look like three flashes at about 1 second intervals followed by a 2-3 second pause then 5 flashes at about one second intervals. There will be another 2-3 sec. pause between codes. Write down all the codes. Turn off the key. Remove the jumper wire from the test connector. You can look up the codes on-line or here or a dealer or parts store should be able to tell you the code definition.
hope this might help.I've used on other makes of vehicles a paperclip and unfolded it and stuck it in where they get diagnostic readings from until check engine lights starts to flash. then bought book to car and read flashes of check engine light and book told me what they meant
i have a 93 toyota camry and going down the road just giving it a little gas it will shut down. it will run great setting their but get to go no more then 20 mph driving me crazy can afford to get a pro but i need to know how to do the check engine light obd two will not do it help going crazy
Open the hood. Locate a small grey box by the firewall, roughly 1.5 x 1.5 inches. It has a cap that will lift up, but it will not come off. Under the cap, located the terminals E1 and Te1. Using a standard paper clip, "jump" E1 and Te1 together. Turn the key on. Obnserve the check engine light; it will flash, pause and flash again. Count the flashes.
Examples: 2 flashes/pause/4 flashes is code "24"
1 flash/pause/5 flashes is code "15"
Get the codes & get that info back to me so that I will be able to assist you with your issue further.
