I have just had the oil changed on my 1999 Silverado, and despite re-setting the message center and disconnecting the battery, the 'Check Engine Oil Level' message does not turn off ! Could this be an oil sensor problem ?
Has anyone else experienced this ? It's going to become annoying if I can't turn that message off. Any suggestions please.

1. locate oil pressure sending unit
2. inspect wiring
3. remove connector, clean with electrical cleaner, reinstall
4. if still error message, replace sending unit. good chance you have several, not uncommon.

Thanks ukrkoz, that could be the issue as I lent the truck to my son a couple of months ago and I don't know where he took it, but the engine compartment is covered in mud and dirt etc. I have been meaning to clean it.
I am having all kinds of message center issues...4WD Service (I found out that it is only the switch that is faulty though)....my ABS is acting up. The truck sucks. Never buy a vehicle from a friend !

simple things sometimes go long ways, hope it'll fix the issue.
service 4wd is scary, but only 60 bucks and 5 minutes labor job.
ABS might be due to the same mud/crap everywhere situation. you could either try to clean sensors from the outside, or remove hub and clean it. sounds like your truck needs a good steamcleaning, he-he. i'd just take it to pressure washer, get on ramps or lift, and wash all i can.
no, you CAN buy from a friend. just not a clunckerado. those are not good quality made vehicles. oh, sorry, i understand that SOME of you have them running well into 300K miles without any problems. exempt only confirms the rule, though.

The truck was in Texas for a while, so you never know what crap it picked up in that state. I'm going straight to one of those do-it-yourself car washers on the way home ! I also have a 1994 GMC Sierra (basically the same truck) and it runs great and has never given me the problems the Chevy has. Live and learn I guess.

mine was assembled in canada, maybe that's why. i had taurus assembled in mexico, it was total disaster.

anyways, i'd rather have you rent pressure washer, so that you can get truck on ramps and wash hubs throuroughly, it is very hard to do in one of them public places. of course, you can take ramps with you. good part is - they have engine cleaner in those washeries, and you'll need plenty of that to start with.
also, check for loose/torn wires for abs sensors. but in general, they say that grease/tar/caked mud on rotors can cause sensors to not function. but then again, abs is notorious for going down fast on silvies either. scan it at parts store for error codes maybe?
good luck.

Hi,
Before you pressure wash a modern engine you should be aware that there are many sensors & electronic components that can & will fail when exposed to this. There "was" a time when you only had to cover the alternator, coil, carb. ect., with some plastic. A friend's brother washed his 01' chevy as you described and had to have a wrecker tow him right from the car wash bay.

he does not need to wash engine. he needs to wash radiator and hubs.

now, without stepping on anyone's toes, i have pressure washed EVERY engine on EVERY car we ever owned, from 84 to 2006 models. had trouble only once, and it was easy fix either, i just started covering distributor on that car with plastic bag.
every modern car has all connectors sealed not only with silicone rubber seals but, also, with dialectric grease. esp on trucks, as their engine bays are wide open to elements from underneath and they are designed to run through puddles, mud etc. and not only modern ones - watch TopGear, when they had 3 old british cars FILLED WITH WATER - and they would still turn the key and drive it. without any electrical damage and with drivers inside the water filled cars, breathing through snorkels.
