Silverado :: 2008 Z71 - Check Engine Light Came On
Aug 7, 2013
recently my check engine light came on, I had the codes read, the tech said that i had air getting into my fuel system, i replaced my gas cap. my light is still on, he also mentioned some kind of emissions sylinoid may need replaced, or a vent valve idk.
I recently drove up to Sandusky OH for the weekend, my light didnt come on til i refuled with gas containing 15% enthenol. the engine is running fine, no miss, has good power. I ran it down to a 1/4 of a tank and filled back up and the light is still on.

I have a 2003 silverado 1500 4x4. The check engine was on along with the abs light. I went to advance and let them tell me what was going on. I don't know the specific code but it said the passenger front abs speed sensor was bad so I replaced it along with new brakes, rotors and calipers. Now the abs, check engine and red brake light is on. There is also a message telling me that the brakes need serviced. I went back to advance and let them tell me once again why those lights were on and it was still the passenger speed sensor bad. What could be going on with it? Before it was replaced the red light never came on but now it is.

1996 Silverado 350 engine. When I turn ignition key on, all system check lights come on as they should except "check engine soon". If I connect code reader the light comes on and will come on the next time ignition is turned on but only one time. The second time you try it, it does not. What would cause this?

Ok so I just replaced my mass air flow sensor about a week ago. My check engine light just came back on and when I scanned it it said mass air flow sensor. What could be causing this to happen again? The codes are P0102, P0440, P0440.

First of all, its 5.7L V8, it's been very well maintained, I've had my fair share of problems but nothing that has been that serious, except for the "check engine" light for the O2 sensor.
For about the last 4 months i've had the problem of the truck sometimes jerking while on the road. Once i started to speed up it seemed to not speed up which when it did, it jerked a bit. That was in the beginning.
AS OF NOW, the jerking has stopped but every now and then when i pull out of the garage and start to turn onto road it turns off, but all the status lights are left on. & when turn the key to turn it off and restart it starts again every time. Ive noticed that i was better off with the "check engine" light on then now because every time it is off it has these problems.
Also, when I barely start to tap the brake, again not all the time, sound skips on the radio. & this always happens when i tap on the brake & this happens more frequently when the "check engine" light is off.

I just bought this used truck, 2005 Chevrolet Silverado 1500 extended cab. I noticed some shaking while in idle when I got it back home. The check engine light came on a day or two later, and I recently had a diagnostic test ran on it at the local AutoZone. It came up that I had a P0135 o2 sensor (bank 1 sensor 1) malfunction and a P0101 Mass Air Flow Sensor signal performance issue. The check engine light comes and goes. I stopped by Walmart for about 10 or 15 minutes and when I got back into the truck, the issues reoccurred. For about a minute, the check engine light actually started blinking! And then went away and started running normal again. Its upper confusing. I bought some MAF cleaner to use on it tomorrow and figured that wouldn't definitely clear up my issues, but I'm still wondering if the MAF sensor is enough to warrant the CEL to blink like that?!

I have a 2001 chevy silverado 3500 6L gasoline engine.
I have been getting a P0307 random multiple misfire #7 on and off for a few months now, occasionally the P0300. Check engine light comes on when I am going up hills, often under heavy load and sometimes when the truck is cold in the morning and the truck starts to run rough until the code clears, which it does pretty quickly usually. I have replaced coil, crank sensor, cam sensor, fuel injectors. If I unplug the battery overnight the code will be cleared and the truck will be running just fine the next day.

I have a 2001 Silverado and for some reason all the dash lights on come from check engine to the abs light gas gauge goes to empty then back to normal 9 times out of 10 these lights come on. It has done this for a while and doesn't effect how it drives, I am possibly wanting to sell it and cannot explain hat it runs fine with this problem. Where do I start to figure this problem out .

I have a 1998 chevy silverado z/71 4x4. I had a water leak and had the intake manifold gaskets replaced. Ever since then, the check engine light comes on and it soots up the o2 sensors and the 4 plugs on the right bank. It may run good for a month or so and then it starts all over again.

Just had my lexus dealership do the ELF recall. While it was in there I had them check to see why my check vsc light comes on randomly which sets off the check engine light.
They came back and told me that my water pump is leaking, what are the future problems of a leaking water pump?
They said the check vsc light is coming on, in their words is "found center y pipe, gaskets leaking at front pipe, may still need to replace converter pipe." So what does that mean and what do I need to do?

I have a 2008 Mazda CX-7, I take it in routinely for oil changes. somewhere between oil changes, there was an oil leak that had developed. no warning lights came on - no check engine light or oil light but the levels were low. I don't know how long it was leaking for, there was never any oil in the driveway or garage.
Any way, I took it to my dealer when diagnosed it with a dye test and told me that I needed to replace the oil filter, gasket and the entire oil cooler to properly fix the leak.
My question is for an opinion as to how urgent this repair is or if I should try and take it to a local mechanic, not my dealer. I have to say my dealer's service is less than desirable anyway. I have been checking the oil levels since I had it in on the 20th of January and it has not gone done. there are small spots on occasion on the driveway but nothing too major and I have not had to add oil to it since I had it looked at.

I was wondering if this seems reasonable. I just bought a used 2008 Prius top trim package with 107,00 miles on it this last month. The first day I owned it a check engine light was triggered. The guy I bought it from hooked it up to his computer and cleared it to then try to trigger it again. This happened when I first turned on the car. I started backing and then it turned on. I didn't know what caused it as we couldn't trigger the response again. It's been a few weeks now and 1 trip to the shop for some repairs. There have been no problems what-so-ever since then and my Prius just started getting close to the 50 MPH as advertised after a tune up.
Today when I'm driving, as the seller did mention before could happen, the right headlight turned off. As he had told me before, just turning the lights off and turning them back on will get it working again. I did this and as soon as I did the check engine light came on. I go back to the night I originally had it happen and I was probably in the process of turning on my lights.

I have an 05 silverado 1500 crew cab z71 and i have a little bit of an issue with my Check Engine Light being on. The problem is when I tried to pull the code from the computer it wouldn't even read that it was plugged in at all. I talked to a buddy of mine and he said that could possibly be the reason its on.
What I am trying to figure out is what i have to do to remedy the situation so that i can actually be able to pull codes in the future. My truck inspection is out and need this light fixed.
Also every once in a while my battery light comes on and it says i need to service my charging system also because I have never seen it before.

So around September I changed my oil to mobile 1 extended performance full synthetic. Since then my check engine oil level light has came on twice, today being the second time. Both times it was at the add mark. The truck does not leak ANY oil, what might be going on?

I have an 08 tdi - this is the 5th time that the check engine light has come on, and again it is the exact same problem. they have replaced the sensor twice, and every time it comes on, they just clear the code and set me on my way.
VW of Fairfax, has my car, as it's all 1 mile from my house, but their service guys suck, refuse to give me a loaner, tell me to wait an hour, and 5 hours later, call me to let me know they have escalated the issue, but that i can come get my car and it's safe to drive on. I do not deny that a exhaust temp sensor is going to prevent me from driving, but I do not like or think it's fair that if my check engine light is on, i should be driving the car.

My son had his engine replaced with a new engine due rod through engine. new engine had 4,000 miles. mechanic installed and check engine light was on. code showed o2 sensors needed to be replaced. these were replaced 2x and light still would not go off. It was taken to the dodge dealership in March 2011. ecu was found to be bad and was replaced. ecu continued to show bad o2 sensors. dealership replaced with manufacturer o2 sensors. code then showed "lean engine". The dealership could not even begin to tell us what was wrong unless they did more diagnostic testing for another $300 - 400 and that was not to fix the problem! Decided that was ridiculous. Took to an outside mechanic. Testing was done and showed that the fuel pump needed replaced. This was done. I don't believe anymore codes are coming up (this needs to be confirmed) but the engine light won't go off.

I just bought a 2008 Hyundai Accent about 2 weeks ago. It has 65,000 miles on it. One week after purchase the check engine light came on. The dealership looked at it and said it was just a leak from the gas cap. So I purchased a new gas cap and the light is still on. I had the guys at AutoZone hook it up to their computer and they said the same thing. They also said that if the light is still on after putting on a new gas cap it could be the fuel injector or a vacuum leak. It has been less than 30 days that I have had this car. What is my next step here?

I have a 2008 Toyota Yaris Hatchback S. it has 99008 miles on it and while trying to drive up my drive way (which is covered in ice and snow) I got stuck and before I realized I was stuck my check engine light was flashing. As soon as I stopped the car the light turned off. I was wondering what I should do.

I have a 2008 Prius that I purchased used last year. It has just shy of 139,000 miles on it. Recently the check engine light came on, and I dropped by AutoZone to have them pull the codes. They are as follows:
C1241
P1121
P3193
I haven't been able to find a full explanation of the codes online, so I need to know what they mean, how much it would cost to fix, and how urgent the repair is. I will be going on a 5 1/2 hour road trip next week, so I want to make sure I'm not going to break my car (or myself!) by doing so with the engine light on.
