估计是某个SENSOR出问题了

Hi buddy,

I got the similar problem as you. I have a 1995-Mazda 626 Cronos,every time I mount on the highway at about 80km/hour, the engine light is on and back to off 1 minute later. I went to the dealer, they put a computer on and checked the code, but it was nothing there. I was told to use extra clean gas, I did, but the light was still on and off. This happened from one and a half years ago till now. I am just wondering what I can do.

I would appreciate it very much if someone can give me some suggestion!!!

不懂别瞎摆和。:flaming: Sensor问题灯是常亮不熄的。

照你所说,这绝对是一个危险信号!是机油和冷却系统有问题!赶快去Dealer检查。否则有烧缸的可能!

Hi 158,

I am Wangwang. Which car should drive in, funhouse's or mine? My engine light was on, then off automatically about a minute later. And this condition has kept for 1.5 years.

Thanks a lot!
 
去做个电脑检测,$49.99 大多数店. 7成是sensor, 像Oxygen Sensor, 是会有时让引擎灯亮, 有时灭的.

Hi Wangwang,

If you check your manual, you will find an advice. if engine check is on, drive slower than 50km/h, go to see dealer.

However, lots issue will triger engine check being on. Sometime it's not important at all. In my case, my enigne check had kept on for one year.

In funhouse's case, he only meets peoblem when driving over 100km/h. It's means that there is a big probability of a defect that exists in his cooling system. That's very dangerous.

Did you check his car? It's your business that you just avoid this warning, cause you know your car well. But are you sure he is 100% in your shoes? Be On the safe side, I strongly suggested him to see dealer. Am I wrong?

Thanks a lot!

BTW, funhouse, it only costs you $40+Tax to get the error code. Then you can decide fix or leave it.
 
Tks 4 U advice!

Thank you so much, guys! I really appreciate your advices. My car works well normally, and seldom exceeds 100 Km/hr, so the flag for engine service doesn't often appear. Does that mean the engine is ok for the lower speed? or it will not destroy my engine at this speed?

Besides the flag remains unless I shut down the engine.It seems different with Wangwang's. Bro 158, Could you tell me where the mechanic is? I heard the Canadian Tire is free for checking, is that true?

no free meal since 1900

我遇到同样问题,CANADIAN TIRE 35元,说速度表的SENSOR,有问题,但我的 速度表SENSOR 在DASHBOARD 下面,要3,4百更换,我就没理他。前段时间,偶尔出现了一两次。

我认为,CT并没有帮我找处真正问题所在!水平问题!

还请专家指点12!
 
if you go to dealer, they will not charge you for just check the code. at least Walkley Nissan didn't charge me for that several times. because it is a yellow light, it is not very severe problem. just keep your eye on it and check it in your dealership when it always on.
 
as I know, most common problem with engine light is mulfunction of O2 and knock sersors. You should do your job in weekly engine oil level check.
