Topic: 车上“CHECK ENGINE” 的黄灯亮了，还差十天换机油(上次换后跑了4000KM，2个多月)，会不会是该提前换油，不过开车没感觉异样，可千万别有什么大的隐患。各位DX有无类似经验，多谢！！！ @埃德蒙顿华人论坛:埃德蒙顿枫下论坛 The Rolia Forum of Edmonton

u'd better make sure when it comes on and the at what speed it comes on. for my example, my Engine Indicator Light comes on after 10 mins' driving at highway...hoho, coz the O2 Sensors is too old ... -trafford(transmigration); 2001-11-18 {39} (#265993@0)

it depends. the original O2 sensor is very expensive, for example MAZDA O2 sensor is about 190(r/s) and 220(l/s). go to Canadian Tire to check ur engine. it will cost u about 88.20 at most. -trafford(transmigration); 2001-11-18 (#266165@0)
forgot to tell the universal O2 sensor is just about 100 bucks more. u'd better check ur car at a professional auto center, such as Canadian Tire AC.Then get the check result and ask for a Chinese auto service company to c whether they can fix it and maybe u can save ur money. -trafford(transmigration); 2001-11-18 {128} (#266172@0)

也该换了。 -alohamac(aloha); 2001-11-18 (#266032@0)
Usually it has nothing to do with oil change. Other more important parts. You'd better drive carefully and have it checked ASAP. -poohbear(nothing); 2001-11-18 (#266089@0)
I changed oil yesterday, After 30 minutes' driving, the light is off now, only because the engine oil is too dirty, thanks for your guys help. -cacross(cacross); 2001-11-19 (#266745@0)
I heard many people like to change O2 sensor if check engine light was on. It sounds like the only reason? No, You will find CEL come back after you do that, also an O2 sensor is expensive. Try to diagnose the car before you do something. -readingcode(Reader); 2001-11-19 (#267152@0)

in my case, i checked it in Canadian Tire Auto Center, they told me my O2 sensors are too old... :(( -trafford(transmigration); 2001-11-20 (#267788@0)

Maybe. I checked many O2 sensors, only 1/10 of them needs to be changed. If you have money, try it as your experience. -readingcode(Reader); 2001-11-20 (#268007@0)

faint, i mean the driver should make sure what happened to his/her car if there is any indicator light comes on. it's no of business of money. -trafford(transmigration); 2001-11-20 (#268087@0)
