Check Engine bulb finally burned out... Ha

For the many years I've owned my '01 XJ the Check Engine bulb has been on almost non-stop. First was when my Pre-Cats burned out which was causing issues w/my O2 Sensors, etc... after ~ 1 year I finally broke down and changed all that out...

For the last couple of years I've been P0456 - Slight emissions leak, which I thought I'd resolved recently after finally buying a smoke machine and finding a small leak in the hose near the canister by the gastank. Fixed that and replaced the old gas cap w/a new Mopar cap... now my CE light was intermittently on/off/on/off... until finally it just was OFF!!

It didn't come on when I first started my XJ so I hooked up my OBDII scanner and yep, still had that stupid P0456 code... but the bulb was finally burned out. HA

I also had a bulb in the center part of my gauge cluster burn out a couple months back... so I suppose it's time to replace them all. Perhaps a good time to upgrade to LED's?

I have seen links and posts about LED gauge bulb replacement so I suppose now might be a time to do that. Any tips / tricks / pointers / regrets / links you can provide are greatly appreciated.

Knock on wood... my '01 XJ is still chugging along as my DD!!

Thanks all.

I love it when my Jeep fixes itself.

On mine it is the washer fluid level bulb that has mercifully burned out.

That's funny! I sort'a feel the same way about replacing the CE bulb...

Here, that's the first thing the emissions people look for, no light, no inspection!

I disconnected the washer warning sensor. the washer warning light was very irritating to have on at night. A low washer level is hardly worth a warning light.
A good part of my life I drove a car that never had a washer, and another that had a hand operated washer of limited effectiveness.

They have them in '90 XJ's?
I just thought it was a '97 and up thing cause of the washer reservoir being buried in the fender where you can't see it.

Well, my '92 has one. First thing I ever fixed on it after buying it was to replace the sensor in the reservoir that controlled it.

My 86 had a low washer light. Funny thing, the truck didn't have a computer, so the CEL was a dead socket on the cluster. It never had a bulb.

In my 92, the computer didn't have anything to do with the low washer light - just a microswitch tied to a foam float on a little assembly mounted in the reservoir.
