View Full Version : Check Engine Light

11-15-2010, 11:19 AM
I was driving to work today and my CEL came on. Is there a way I can figure out the code on my own? I don't have many tools, but have heard you can count the number of times a certain light blinks. Any thoughts or recommendations would be appreciated.

I'm assuming that being your truck is a 97 that you have obdII. I've never dealt with an 80 so I guess I could be wrong there. Anyway, if it is obd compliant you can just take it to autozone and they can check it for free. There might be a way to get it to flash the code as well, not sure.

If you are in the Aurora area you can swing by my place and I can get the codes with my scanner for you.

If you had an FJ62 you'd be counting blinks... but your 97 has a much more upgraded system called OBD2. So you need to get a reader... just go to Auto Zone or Advanced Auto Parts and they can read it for you for free. Then post up here what the number is.

Or, hook up with about half the membership here who has their own readers... I've got one in the 80 at all times, but I'm not around this week and kind of far from you.

I'll put my buck on P0401 though, for the pool.. :)

edit: satchel types faster than me.

Thanks guys!!! I'll do that over lunch and then post up.

Nakman, are you on the northside? I live in lakewood, but work in broomfield.

There is a checker or autozone up on mcaslin just north of 36 that I know of. Just make sure you use the diagnostic port under the dash, by your left shin. I tried using the one in the PS engine bay the first time, doesn't work so well :lmao:

OBD2 codes are universal. Once you have the code, you can find out what it is HERE (http://www.troublecodes.net/OBD2/). Or just post it up. Likely the guy at autozone will tell you what it is.

yeah Nick I'm north side but I'm traveling all week, will be back Friday though if you don't get this figured out by then.

Last time I was at Checker I overheard them refusing to pull a code for a guy.. so I'd maybe try one of the others first. :confused:

If you come down south I've got a code reader as well :thumb:

I'm with Nakman on the code but I've only ever had 3 ever pop up so far (all on the 80): P0401, P0171, and P0133

Or you could use this as an excuse to buy a scan guage or ultra gauge! :D

Any Autozone, oreillies, and pepboys can scan your computer for free. Just pull up and ask. I also have a code reared. C470 & 285

Wow thank you to everyone for the offers of help and to use your code readers!! My day sort of blew up, so Iíll try to hit autozone after work. Iíll let you know what the code is. Should I not be driving the truck till I get this fixed? Everything seemed ok (engine temp, oil levels, ect were normal) but please let me know what you guys think. Thanks again, I definitely owe you guys a round or two.

No worries at all about driving the thing.. there are some conditions that will make matters worse if gone unattended but you're working on it, don't give it another thought.

it's code P0116. which i was told relates to the ECU managing the engine & coolant temperatures. They said there are 2 parts that relate to this. One is a temperature sensor and the other is the ECU. All the parts are working ok and they recommended clearing the code and seeing if it reappears. They did say that if it came back I would probably have to replace the ECU if the other temperature sensor was still testing ok. I was also told, that there was an update from Toyota relating to this issue in the 97 land cruisers and recommended replacing the ECU with this new update.

Has anyone else run into this code or had the ECU replaced? Iíve called around to check on prices to replace the ECU and itís something that I canít afford to have a shop do right now so if it comes back Iíll need to look at doing this myselfÖ Please let me know what you guys think and THANKS as always your thoughts and recommendations!!!

Toyota Tis P0116=

P0116 is a new one to me...I'd probably do a quick search of MUD too though just to see what others, if any, have found with this.

I have to imagine that a new temp sensor has got to be a lot less expensive than a new/used ECU so even if the tests showed the sensor is ok, I'd probably replace it. Sensors can get flaky and be fine when tested only to be flaky at other times (i.e. when heated or cold etc.). One of my O2 sensors tested fine on the 80 90% of the time before it threw a code...

As for the work...No need to take the 80 to a dealer. Lots of help in the club whether free amatuer help or reasonably prices professional help :) - We can give you names/suggestions based on where you are and who has the time to help you out. I've gotten to the point where unless the work is something I'll likely have to repeat in the future (front axle service, brakes, etc.), I would rather pay someone in the club to fix the issue and be done with it and most likely never have to deal with it again.
