Check Engine Light never comes on

[rsthomas]

Hello,

My check engine light never comes on(apparently). Seeing no problem I took it to DMV for inspection and they failed me emission due to some ODB Codes. I had it repaied for $450 and took it back to DMV and all the codes are cleared but the Check Engine Light itself is not on. Usually when we start the engine it comes on and goes off if there are not any problems.

I am trying to see if I could fix this myself ( save some $$$). I think the check engine light is on the bottom of the odometer along with ABS light .. the ABS light comes on.

Could this be due to the ECU-B fuse blow? or the light bulb itself ?

Any help is appreciated.

Thanks

what was the problem in the first place? (the problem that cost 450)

you did not pass after second visit to dmv?

i thought dmv only checks for working lights, seat belts, license plates etc... not obd codes

what is the exact reason for no pass? obd codes? check eng light on?

EGR Valve and O2 sensor was replaced.

No my car did not pass. It is a bit funny, first time they didnt check it, second time they did. The guy said the Check Engine Light is disconnected. There is a FAIL under Check Engine Bulb.

Thanks

well you need to pull the speedo from the dash and change the bulb, look for any cut wires, you can search on here for how to change it.

Thanks and I will try that.

Is the fuse only for this 'Check engine light' ? or for all the lights on the speedo? I was going to try to replace the fuse.

Thanks and appreciate everyones reply here.

No dedicated fuse.
Just pull the dash board, then the instrument cluster. Disconnect it, look at the circuit board on the rear of the cluster for any loose/broken connections, and also pull the CEL bulb to inspect.

You may want to visit Autozone to read out remaining codes for free.

I don't know what year, but the OBD-II scanner can also tell you if the light should be on.

Theres no fuse? Thought I saw the box diagram that had a check engine symbol in it. Hmmm maybe it was a corolla or something.

Yeah, take out the instrument cluster and check out the bulb for the check engine light. They hardly go out, but got to check everything, and check for any frayed or damages wires that are connected to the cluster. Also, good luck removing the cover dash thinge that is covering the instrument cluster. Oh, camry makes it difficult but corollas make it so simple.

I'm curious how many miles your car has.

*If* the problem is a burnt out bulb, that's a simple fix. As mentioned by another poster above, all you'd have to do is remove the frame around the instrument cluster, then remove the cluster itself. Then you can just twist out whichever bulb (from the back) needs replacing. A pair of bulbs is a couple bucks at any auto store.

If it's the wires themselves, then you may need to inspect those.
