My name is Cole, I love my truck and my Jeep. But I am going to shoot straight out of the gate with a question. For starters, I have a 2002 Silverado 4X4 it has 142,000 miles on it. But, the check engine light cut on the other day and I stopped by the local Advanced and had the code read. I am not to savy with all of the codes but essentially the gentlemen told me that the problem was probably my gas cap. I purchased and new one and it worked. The light went off and I had no problems until this morning. I drove the truck to work and the light was not on. I parked, went into the office for a few hours and when I stepped out for lunch and started her the light came back on. I am just curious if any one out there may know the problem. Thanks!

Hello Clemson69 and Welcome aboard!

 

Take your gas cap off again and re-tighten it......obviously...and I'm sure you've done that already. :(

 

If that doesn't work this time, you'll have to have the code read again.

 

AutoZone stores used to give out free code books with instructions on how to read them and what they meant and a GM shaped key (for inserting appropriatley into the diagnostics connection pins, of course).

 

At least they USED to. Haven't been in quite awhile, so I'm not postive this is still the case.

 

If they still give these, at least you could track things down. Your truck will remember for several starts what previous code faults were, so you can still check even if the light resets.

Welcome!

 

If the code is for the gas-cap, you'll have to have it reset again to clear the code. It will clear on it's own, but takes a while (50 starts ???).

      Oil Consumption

      By Chuck FB · Posted

      Ok that confirms the extra quart theme they are still going with which must mean they have noted some initial use more so then some engines and probably the bigger factor in all of this probably isn't the engine so much as its the insane distance or OLM that lulls a lot of the driving public into driving their new vehicle off the lot and not even doing one short interval oil change because the manufacturer doesn't say different and if the dealer follows that logic as well. Selling the rarely needing to be serviced concept seems to go over well with the public that wants to get away with as little as possible for dollars spent on the vehicles maintenance and I bet there are 3.0 engines just like other vehicles out there that never have their oil checked by the owner which goes back to why they probably felt the need to add that extra quart to avoid a costly theme.    Speaking of cutting filters open, it was probably over two years ago now that a youtuber who buys vehicles to do longer term reviews and pulls a fifth wheel through the mountains of Colorado on summer trips and that becomes part of the testing. Anyway he had a GM HD with the 6.6 gas and a Ford 250 with the 7.3 gas at the same time and of no surprise the Ford had more power etc but somewhere along the way in the few thousand miles he put on the truck, he changed the oil and was seeing glitter and cut open the filter and yeah, things were not looking spectacular. The truck about that time or soon after seemed down on power compared to what it had been and then threw some engine code, I expect the cam/lifters were failing and so he brought the truck back to the dealer and made some deal to get out of it as he knew it would sit for months waiting on a new engine as they were so backlogged at the time. He kept the GM for some time after that using it exclusively until he sold it after buying his next vehicle to do a review on. Definitely the filter can tell a story when things are starting to go sideways, but it would be a sickening feeling to cut it open and be faced with an ugly mess like that and be running a magnet through the pleats and the oil on the dirty side of the filter and see all the fines sticking to the magnet.    The dealer may have some ideas based on experience as to where that coolant smell is coming from, I would imagine if they can't find it but its smelling they would put dye in it to they could give it a run cycle and use the black light to see where it pops up, if its a hose connection, water pump, rad or even a head gasket etc.

      frustrating P0446 code

      charm.li (website) has the vehicle-specific diagnostic procedure for that code, you can use to find what the cause of it is.

      Oil Consumption

      By KARNUT · Posted

      It’s at the point of amusement. I’m retired I have time. It’s fun seeing people try to convince me I’m using oil. I’m buying oil at the prescribed time. It gets drained and new goes in. Do I add in between, no. My oil doesn’t even get dirty in 5k miles. I don’t even see any drop on the stick. I check in the same place. All is well.
