Question about 1993 Toyota Previa

2 Answers

Oil Light blinked instead of check engine

I did the old paper clip trick to check the code, because my oil light has been on, for a while, I know it needed something but not sure what, not the check engine light came on, so thats why i checked. Well, when the clip was in, the check engine light stayed on but didnt blink, the oil light did, twice, and then three blinks. What should I do, go with the code 23 diagnosis? Even when it wasn't the check engine light that gave me the code?

    and yes i checked the oil level, its full and clean. It does sometimes shudder and tries to die on me when I've been maintaining high speed and then slowing down to a stop, I throw it in neutral and lightly tap the gas.

I'm going to walk you through the "Oil Life Reset" step by step. ***BUT FIRST: It is important to know that this procedure is to only be performed after the oil change has been done.*** Take the ignition key and a "BIC" pen with you. Sit in the driver's seat and put the key in the ignition, Look at the gauge cluster and find a small black rubber plug (It is in the clear plastic lens), remove the rubber plug, Turn the ignition to the "Run" position (do not start the engine", Take the pen and stick it gently into the hole (that the plug was in), Inside the hole is a small button. Gently depress the button with the pen and hold it in until the oil light turns off. Now the "Oil life" has been reset. Remember to replace the rubber plug back into the service port. This will keep the internal workings clean. As far as the "Engine light", it has nothing to do with the "Oil Light". You can try resetting the ECU and see if it comes back on. To reset the ECU is just a few easy steps. Locate the fuse panel, remove the cover, identify the ECU fuse and remove the fuse, turn the ignition to the "Run" position (do not start the engine), leave the key on for five minutes and replace the fuse. You will see the "engine Light' flash a few times and then go out. The ECU is now reset. If I can be of anymore help please write back and I'll do my best. Good Luck.

Interesting. It could be that the circuits are shorted out inside the instrument cluster. The oil light should be on when oil pressure drops below 5psi. Oil level in the engine would not have a direct effect on the warning light unless the engine was empty.

When i start my car it dies on me a couple of times then it eventally starts, could this be the fuel pump?

Hi, It could be various things & like anything else try the process of elimination. To make sure it's not electrical(fuse or computer issue get Do the "Paper Clip Trick" :a simple paper clip bend it into the "U" shape- *Find where the diagnostic "Tester" is(Or go to Auto-Zone) They will test it free(Note where they plug in the Diagnostic tester-because YOU can do that test with a paper clip bent in the shape of a "U"...Then start your car -You will see a series of Flashes/Blinks(YOUR DASH LIGHTS older cars it may be check engine or oil light), *The first set of lights Flashing on Dash may be your engine code. *Then watch & count- EACH SLOW FLASH(Light on Dash or older cars it will be engine light/oil light) is "10" & EACH FAST FLASH is "1"...Your cars computer will show you what is wrong if it is electrical or computerized with a sensor. After it shows you a code it will DOUBLE FLASH- IF THERE IS MORE THAN 1 THING WRONG & and show you that 1st code double blink & start a different code...Write down a SLOW Flash/Blink as a short line & any FAST as a DOT...the add Slow=10 Fast=1 *Then go to a public library(you can do this before you do the test & Xerox the pages with the Diagnostic codes so YOU have them on hand if your car starts acting up). *Ask a Librarian to use THEIR COMPUTER as a GUEST- have them help you USE THEIR PUBLIC LIBRARY SITE: Then tell them you need to go to the PAID WEBSITE(FREE IF YOU USE THE PUBLIC LIBRARY'S SITE). It's Called ALLDATA.COM (This site has trouble codes,Diagnostic codes-exploded views & shows you prices of the parts & how to put on/remove parts). *It will ask for Your Cars Info: Year,Make,Model & Engine size. **Check connecting wires(make sure from battery to starter there isnt a cut(or frayed)wire. *Check your battery at an Auto zone for free to make sure it has enough cold cranking amps/paks. Check fuel filters & Air Filter, Check your Spark plugs(make sure they are gapped correctly(and aren't gunked up or in correct firing order & all working...Check your Oxygen Sensor(on exhaust manifold), Check for Vacuum leaks, check also & make sure your catalytic converter isn't full, Check your fuel pump to make sure it's pushing the fuel through. I know it's a lot- but it's a $$$ & get to know your car! Have a Great Day & Good Luck! Xx, JazzyCleveland PS<Remeber>.

94 olds cutlass ciera service engine soon just came on what should i do

If the service engine light is on, this is in a way a good thing. This means that your vehicles computer has detected a problem and the computer has stored this information for you. Now the trick is how to get that information from an older system like you have (they changed the system in late 1996). You need to find the data link connector which should be under the dash on the drivers side of the vehicle and I believe yours (don't quote me on this) is on the right side of the steering column by the brake pedal or even mounted on the bottom of the dash (same area though). Below is a picture of what this data link plug looks like. Now have a peice of paper and a pen also a paper clip (one of the bigger ones are better. Now take that paper clip and kind of bend it into a "U" and insert one end into the letter "A" spot on the plug and the other end in the "B" spot on the data link plug. After you "jump" A and B turn your ignition switch to the on position without starting the vehicle and look at your check engine light.. Here is where the pen and paper come in. The check engine light should start blinking. The begining or starting blinks should goes as "blink" (one blink) - Pause - and the "blink blink" (2 blinks). This is a code 12. A code 12 means the system is working. It will blink a code 12 three times. After the code 12 there will be a litttle longer pause and then another code(s) should start. this is where the counting comes in. so after the code 12 and the pause, if it blinks 4 times - pause and then 2 times, this is a code 42 ( am using a code 42 just as an example). It will blink the code 42 (or whatever code) 3 times and then move on to the next code. There may only be one code but if there is more they will go in order. When it goes back to a code 12, the diagnostic is complete. Write down what codes you retrieved and these codes will lead you to the direction of the problem and there are testing procedures that go with each code. Until I get those codes, I am unable to help you any further. Once you get code(s) you can reply/comment here what they are or feel free to email me directly at with your vehicle information (make, model, year and engine size) and I will be happy to try and help you diagnose what the problem is such as a sensor or whatever along with tesing procedures so you're not just replacing parts that are not needed. I know this was a long explanation but it's the only thing to be done at this point. Hope I was able to explain it to you so you understand and I was able to help.

My check engine light came on (blinking) I know that I am behind in oil changes, and I checked my oil, it is low. Will this cause the light to blink?

Your check engine light---indicates a possible system failure,nothing to do with oil
You have it checked for codes,diagnose the issue and repair

Your oil should never be low.
If you go as much as 5000 miles on an oil change and really drive it hard,you may loose a 1/2 qt in 5,000 miles

On-off with ignition 3 times and you will get error code in odometer. Check the code from the internet gods, it will tell you. Probably small evaporation leak detected from loose gascap. Try removing ground from battery for 10 min,then replace. It should go away. If comes back, something more serious perhaps.

2002 Jeep Liberty: Battery cable loose wire was

first, though you mentioned no oil leaking, is there oil in the engine?
Next, if engine runs well and is not ticking or tapping, have the codes checked...most larger parts stores do this free. Once you have the stored codes you can look up what system is malfunctioning.
If engine is making any noise at all or there is no oil in it, DO NOT START OR DRIVE IT...make sure whoever did the oil change knows about this now...If someone forgot to put oil in, they may be buying you a new engine!
At this point it may be something simple but can also be very serious.(hope not)
good luck

Service engine soon

The "Service engine soon" light pertains to oil change frequencies only, there is no code, it will come on at given milages to remind you to change your oil. To reset there should be a small hole in the face of the instrument panel. Remove the tiny plug and push a paper clip into the hole with a slight force until you feel a click. This should reset the light for another 3000 miles. If it does not have the hole than it must be reset by the dealer. Thank you, Dana
