View 2 RepliesChevrolet - Silverado :: 2009 - CEL Came On For Code P0442
The CEL came in on my friend's Chevy Silverado .....so he took it to the dealer for diagnosis/repair. After paying for the diagnosis and repair (supposedly he needed a new gas cap) he was good to go. A few days later the CEL came in. I have a code reader so he asked me to check the CEL code. It's P0442. The same code that the dealer sited. Since we know it isn't the gas cap what are the other most likely suspects? He says the truck runs fine. No drop off in MPG, no misfire, etc.
View 2 RepliesSilverado :: 2003 With Code P0307 Misfire / CEL Flashing
I'm having an issue with my 2003 Silverado, current engine is LS1 from a WS6 Trans Am, mostly stock, stainless headers, no cats, stall converter. I replaced fuel pump a few weeks ago and last week i took a road trip and when I hit the interstate the CEL started flashing. I pulled over and used my scanner and saw that it was P0307. I cleared code and continued on. The only noticeable problem was that it was not shifting into overdrive. After a while the light quit flashing and eventually it shifted into OD.
This happened several more times on a 750 mile trip. I had a mechanic friend check it over and he couldn't find anything, wasn't throwing codes at that time. He check sparked plug, swapped the coil to #5 and still had the issue. Didn't get a chance to check the fuel injector. The trip home it did the same thing. IF it were indeed a bad injector, wouldn't the problem be ongoing instead of coming and going? Took to local chevy dealer thinking they could diagnose it but since it didn't throw a code they couldn't find anything.
Silverado :: Getting Code P0523 - Engine Oil Pressure Sensor?
When my check engine light came on I hooked up the tool to see what code I would get. This is the code I'm getting which indicates a problem with the engine oil pressure sensor/switch circuit high voltage.
Question 1: is this a simple fix and about how much do you think this would cost at a Jiffy Lube or Walmart type place?I'm also concerned because the MIL is no longer on. I'm wondering if I could have cleared it off using the tool. This morning the engine light was no longer lit and my oil pressure guage is reading no pressure at all now.
Question 2: could it be possible to have no pressure? or like the code indicates it's just a matter of the sensor not reading the pressure?
Question 3: is it safe to operate the vehicle? I'm not going to have any money in my budget for at least another month.

I have an 04 Silverado Z71. I am getting error code U1000 on my Scanner. As well as a torque converter code and a front axel code. I can not start the truck. Its as if its in a safety lock out or something.
I talked to a service tech at the lock gmc dealer and he said the U1000 code was definitely the reason it wont start. Possible bad ECM somewhere in the system.
Where can i find a full wiring schematic for my truck ?
Silverado :: 2003 - Intermittent CEL Code P0304 / Misfire On Cylinder 4
My 2003 Silverado 5.3 has an intermittent CEL. I plugged in the reader and found code P0304, misfire #4 cylinder. I changed the coil, swapped the spark plug and wire from #2 cylinder to see if the code would follow. Nope, didn't follow. I swapped the injector also, same results. My daughter decided to borrow the truck and drove it so low on fuel that the low fuel light came on in the drive way. I added about 4 gallons of fuel and now the light went off. I started the engine after a jump start, and the engine really runs rough and now won't stay running. I am thinking that the fuel filter is probably needing changed because of how low the fuel.
I haven't checked the fuel pressure yet and will do that today. Now, what really puzzles me is the intermittent part. Sometimes it will run with no problem, but then the CEL will come on and the fun begins. The Chevrolet dealer says it's caused by the valves turning in the head and when it reaches a certain spot, it detects the misfiring #4 cylinder resulting in the CEL. If I pull in the driveway with the engine missing, go back out in a short time, start the engine and it runs fine. Same thing if it's running fine and I can start it and the CEL blinks and it begins missing, but may stop and run fine. I am stumped and not so sure about the turning valves.

My truck is an 2003 2500hd with the 6l engine and 89k miles. From time to time I'm getting message "reduced engine power". Usually at the morning after 10-15 minutes after starting. I have to pull over, shut it off, wait few seconds then restart it. The ses light goes off usually by end of the day ( or after few hours ). When scanned by chevy tech showing code P1516 Throttle Actuator Control (TAC) Module Throttle Actuator Position Performance. I have new battery with new main cable. TAC Module was cleaned.
View 14 RepliesSilverado :: Engine Power Randomly Reduce During Driving - P1516 Code Returned
Truck is a 2003 1500HD Silverado with the 6.0L 364V8. Last winter I started getting the P1516 code and reduced engine power randomly during driving. After dealing with it for about a month I did some research and discovered in most cases it was either the wiring/plug or the TAC module itself. After going over the connections I couldn't see any visible breaks..etc but I decided to go ahead and change out the connector and about 6inches of the wiring.
After replacement the code hadn't come back until today, probably atleast 9months ago was the last time it did it. Today the code came on four times during a 10minute drive. Before it would come on once during the drive, i'd clear it with my scan gauge, and it would not do it again the entire day. I checked all my connections once again and everything is intact and there is no visible breaks and the connector is clean. I'm starting to think that it was just a coincidence that this problem quit when I replaced the connector, and was wondering if colder weather could have weight on this issue?
After poking around the posts on here and other sites I found that many ended up replacing the TAC module which is on the throttle body. After looking at mine the only way I can see replacing that is just buying a new throttle body with the TAC on it, can't seem to find just the TAC part by itself anywhere. So if I were to order a new throttle body how hard is it to remove/install? and do I have to do a relearn process or is it plug and play?

Silverado :: 2008 Remote Start Not Working
About a month ago, I hit a flock of turkeys in my 08 Silverado, dented my hood above the grill next to the driver side headlight, took it to the garage to have it fixed, now my remote start isn't working. It worked the day that I took it over to have the dealer fix the damage.
All it does now is my lights come on, and I hear the clicking noise under the hood but nothing happens. I also already tried resetting and relearning the key, that doesn't work either. what could be wrong?
Silverado :: 2008 - Brake Lights Staying On
My son's 08 1500 2WD truck has had problems with the cruise control not working correctly. Think I found out why, was following him today, and his brake lights came on. He was on an open road, no traffic, so I called him and asked if he was riding the brake with his left foot. He said No. Told him what I saw, and when he came to a red light, I told him to stab the brake 2 or 3 times, then let up. No change, brake lights stayed lit. He pulled into a lot, and unplugged the connector on the brake pedal arm. Then he turned on the key, brake lights were still on. Connector has 4 wires, I guessed one circuit for brake lights, one for cruise? Or is one for the transmission interlock solenoid that prevents shifting out of Park until you press the brake pedal? Getting ready to go check things with a voltmeter.
View 6 RepliesChevy - Silverado :: 2008 2500HD Front End Clunking
I picked up a very clean 2008 Silverado 2500 HD. W/60K miles. The vehicle has been very well cared for as I know the orignal owner. I have zero complaints with the truck other than an annoying front end clunking. Its very reminiscent to the intermediate shaft issues of my 2003 2500HD.
Basically when hitting very small road imperfections, I can feel/hear a clunking in the front suspension. I can also duplicate the issue by rocking the truck left to right with the steering wheel while going 20-30MPH. I figured, stabilizer links. I put the truck up in the air, & can't find a thing wrong. Links are tight as well as the ball joints & tie rod ends. Were these trucks know for a common clunk like this.

Yesterday I was driving my truck and went to activate the cruise so I pressed the button to turn it on and hit set but nothing happened. The on light was lit but the cruise indicator didn't light up in the speedo. I got to where I was headed, shut the truck off and on my way home tried this again to have the the cruise work normally. Cruise acting up and not work on occasion? I've never had the cruise control act up before so is there something I can check out? Bad connection or something?
