1993 Camry Check Engine Light

I jumped the TE1 and the E1 pins on the connector, the check engine light flashes 5 times, pauses, and flashes 5 times again, it continues and the o/d light flashes repeatedly.

i suppose it is code 5 or 55 not sure, and not sure what they mean, any help is appreciated.

    Is there possibly another code like code 5?

    Would there be a noticeable difference in performance for
    the knock sensor?

    A while ago the brake vacuum switch I believe was replaced.

    I was told this was what caused the check engine light to
    come on.

    No where has the ODBI device to clear the code.

    Is there anyway to do this myself?

    I haven't really looked into this too much as it seems to be a but too technical at the time, I will look into it more alter when inspection time comes around but for now the car is running great. I also read about connecting the two sensors wires together at the computer to trick it, I might consider that later on as well.

  • Luvlexus101 Nov 28, 2008

    I had tried that, the light comes right back on, the interesting thing is that when the car is started initially the CEL does not come on it takes about 15-30 seconds for it to come on. I don't know if this is relevant but when the the pins are jumped the overdrive light flashes rapidly. Also another outstanding issue that I have also posted on this site is the door lock switches dont really work anymore, driver side does not unlock, passenger side does not lock doors

    DTC 55 is indicating a failure with the knock sensor, or the wiring to the knock sensor, on the RH bank. It is rare that they fail, I would take a good look at the wiring harness, the sensors are under the intake plenums. Hope this helps.Please feel free to comment back if you need additional info.

    Thanks for choosing FixYA.

    Check Engine Light Came On Code P0411 What Does This Mean

  • Anonymous Mar 20, 2014

    There is a miss and sometimes the engine light will flash other times the light will just remain on. We have replaced the coils and it fixed it once but is doing it again. Would it be the coils again or another problem?

Therre is no DTC code "5". The DTCs start at 12. If the knock sensor (there are actually 2) was bad, you would have an acceleration issue. The knock sensor changes the timing of the spark to eliminate detonation, or "pinging". Do you have a "Ping" condition/valve rattle on acceleration?
To reset the light, open the hood, remove the 15 amp EFI fuse for 5 minutes. Replace it, and start the car and drive it until it reaches operating temperature. If the light comes back on instantly, you have a bad sensor or a bad wire.

    You do NOT want to connect the sensor wires together. This will cause you more grief than you want, ie a new engine control unit. Before you do anything else, try this: Go out, open the hood, and open the fuse box. Remove the 15 amp EFI fuse, and leave it removed for 1 minute. This will erase your DTC 55. Replace the fuse, and drive the car. If the Ck Eng light does not come back on, you just may have had a spot of moisture or something that would cause a knock. Try that & let me know what happens. The upgrade of my rating to a FIxYa woul dbe greatly appreciated. Thanks.

    The OD light is supposed to flash.

    I read that post about the door locks. Did not get to post because of the holiday and BUSY here...You prob have a bad door lock switch. Post the question again, direct to me, with your e-mail, I'll send you a wiring diagram.

    Thnaks for the FixYa. Much appreciated!

Brainbox light comes up on the dashboard after driving few kilometres. I change it with another one but still the same problem. Toyota camry 1994 model.

Well, that's the check engine light I think. It is saying something is not normal. You can read out a trouble code to give you an idea of why it is on. Turn the ignition on, but engine stopped, and with a piece of wire bridge terminals TE1 and E1 in the service terminal box, at one rear corner of the engine compartment.

The check engine light will then blink. A steady blink 4 times per sec is "all normal".

Trouble codes are 2 digits, and these will be blinked - first digit - pause - second digit - repreat.

So the oxygen sensor fail code (a common one) is 21, and will show 2 blinks - pause - 1 blink - repeat.

There are 22 of these codes

Toyaota Camry 1994 engine won't start, Engine light on

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.

Check engine light just came on 1993 toy camry

First you need to find out what the fault code is that is making the check engine light come on. To do this, locate the diagnostic connector under the hood. It will be a black rectangular connector approx 50mm X 25mm with Diagnostic written on the cover. Open the cover and on the inside of the cover will be a diagram of the connections and their different labels. Locate pins labelled TE1 and E1. Switch on the ignition switch without starting the engine and with a small jumper wire bridge between pin TE1 and pin E1. Observe the check engine light on the dash and you will notice that it will be flashing. Read the diagnosis code as indicated by the number of flashes that this light makes. Each code will be displayed by first blinking the first digit of the code, then a pause and blink the second digit of the code. For example, Code 52 (knock sensor signal) will flash 5 times, pause and then flash 2 times, then a longer pause before it goes onto the next fault code if there is another one. Once it has gone through all the stored fault codes it will go through the sequence again starting at the first fault code again. Due to the many different fault codes that can be obtained it would be better to post another question for the fault code obtained. Good luck!

94 Camry was running fine, suddenly became sluggish

How did you try to obtain the codes? Did you short pins E1 and Te1 in the grey connector under the hood?

When the light comes back on, short the above pins, and get back to us.

Without seeing the codes, I would venbture a guess that you first consider a good tune-up, and use Toyota plugs only. Any other manufacturer will not work very well. I see this every day, new plugs, and the engine runs poor. Toyota plugs fixes it right up. The heat ranges are diffferent in Toyota plugs.

1993 toyota camry turn check engine light off

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.
