TrailBlazer :: 2008 - Secondary AIR System Switching Valve A Stuck Open (P2440 Code)
I have a P2440 code from warning light- Secondary AIR System Switching Valve A' Stuck Open. This started to appear when I took it into the dealer for other issue with transfer case whining when in 4x4. Can this code be associated with something the mechanic did , would they remove any sensors or wires, that may not have put back. Not happy. Are these trucks know for this code? Estimate cost?
View 4 RepliesChevrolet - Sonic :: Air Valve Stuck Open Code / Smoke Or Steam Coming From Under The Hood
So for the past week or so, I've been having problems with my cooling system. (May or may not be related to my air valve stuck open code, just thought I'd mention it.) First thing that drew my attention to the problem was smoke (or steam) coming from under the hood, I let the car cool off, and drove home. During this time I also noticed the heat stopped working. I went to get some coolant in another car and filled it up. Smoke went away, and heat started working again.
Later the same day I checked the reservoir and it looked low so I figured the radiator sucked all the coolant up, so I refilled the resivoir tank. I spilled a nice amount when doing that, and the steam came back. It cooled down again and no more steam, figured it burnt off. The next few mornings on my first drive of the day ONLY, I saw steam. Thought it was the condensation mixing with the leftover coolant that I spilled since it didn't happen at all until the next morning.
Today was the first time it started steaming at night, and the heat stopped working again, even though the reservoir level was mostly full. I let the car cool down, and then I added more coolant and the heat started working again, no more steam either. Looked under the hood once I got home, abt a 20 min drive, resivoir was nearly empty even though car was still warm. No visible leaks on the smaller reservoir hose but there are puddles under the hood.
I've read it could be a leak of course, but also the Cap could be preventing the right pressure to suck fluid back in radiator after expanding into the surge tank, or something causing the tank to boil over....
Car is a 2013 Chevy Sonic with 68,000 miles. Coolant has never been drained/refilled since I bought the car new in 2013.

I have a 2006 Pontiac Montana SV6 with 80,000 miles on it. Recently the dashboard warning "check gas cap" has started coming on. I have replaced the gas cap and cleared the code and it is doing it again. It seems like it is more likely to do it when the gas tank is 1/2 or less full but it also did it today with almost a full tank. The code from the computer said P0455, what this could be?
View 7 RepliesCamry :: Throttle Body Valve Was Stuck Open
About, one month ago my car shut off while driving(pretty scary at the time). I pulled of the road and attempted to start it again. Everything looked good there, but as I was making my way home from work it started to act funny. It would not acknowledge me depressing the accelerator. When I got home, I ate supper, then went to have a look.
The car would turn on, but not acknowledge me pressing the accelerator at all, It did however go up to 30 mph at a snails pace as if it was coasting down a hill. I plugged in my code reader, and it read that the Throttle Body Valve was stuck open. I took it off and tore into to it a bit. I noticed the gears inside the TB itself were corroded and the butterfly valve was locked up.
I replaced the part, and tried to turn my car on with the new TB. All the dash lights are in working order, however upon turning the ignition to crank the engine, the whole car system shuts down. No lights no nothing, besides the car door open sound. The car will remain like this regardless of the key position until I have reset the batter(take off the terminals and put them back on) to which the process repeats itself.
The code reader says no codes are stored because I obviously reset the battery. So now am at a standstill.I believe the old TB froze up, because I had to run in through 3 ft standing water during a storm, and then deployed shortly after(I'm in the service) for a few months while letting the car sit.
Pontiac - Leaks - Grandam :: EGR Valve Throwing A Code
I drive a 1995 3.1L V6 Pontiac Grand Am SE.
My mechanic told me that my EGR valve was throwing a code, so I took it off and cleaned it out and tried to fish out some of the carbon in the air intake tube. I used carb cleaner on the valve and the tube and I sprayed a little bit of air duster into the tube, but it made a funny noise so I stopped after about 1 second of spraying.
When I put it back on, I forgot to snap the wiring harness back onto the top EGR solenoid. I reconnected the negative battery cable and started my car. The gauges red fine. I revved my engine a few times and everything seemed okay. Then I turned off my engine and then turned it back on to listen for any rough idling (that's why I decided to clean the EGR in the first place). Then I turned it off.
When I got out of the car, I realized I forgot to reattach the wiring harness to the EGR. I disconnected the negative battery cable and it sparked a tiny bit. I reconnected the wiring harness to the EGR. Afterwards, I noticed that it had leaked some fluid (I'm guess oil?) into my engine. There was a very small amount of light smoke or steam (not sure which), but it stopped a minute or two later. I've attached a picture for reference.
Is it safe to reconnect my negative battery cable and try restarting my car????

View 4 RepliesBuick - Lasebre :: 2001 Not Starting Properly - Check Engine Light On And Shows EGR Valve Stuck Open
My 2001 Buick Lasebre is not starting properly. I have to pump the gas several times before it will start; then when it is started at low speeds or idle it wants to stall. As long as I can some how keep pushing the gas peddle it wont stall. On the other hand when I am driving at higher speeds, anything above 40 or so it runs perfect. The check engine light was on and shows EGR valve stuck open. I have replaced the Mass airflow sensor, fuel filter, and the EGR valve. I had the code cleared and a short while later my check engine light came back on with the exact same reading. I bought this car only a week ago and was not expecting to have to fix a car I just bought and ran fine while test driving it. I have read may different forum that say that it could be anything from my fuel pump to vacuum hoses, to some other sensor.
View 19 RepliesCamry :: Thermostat Seems To Be Stuck Partial Open - Replacement?
I have a 2003 Camry 4 cylinder and the thermostat seems to be stuck partial open. Gauge does not reach what was normal operating level before. Has not thrown P 0128 code yet. I was thinking changing the thermostat. When checking on replacement it shows 2 gaskets, one paper or rubber gasket with holes and an one o ring. Is this correct and if so where does each go when installed. Looking at the housing it does not look to be to hard a job.

Code is for tcc stuck on. Code p0741 is tcc stuck off. So, it's a sticky solenoid. Which means it may start out sticking occasionally and progress to sticking more often and finally staying on/off permanently? If u get the code/symptoms 1 time, does it usually mean it will happen again, soon?

A couple months ago I was hearing a hissing noise under the hood throwing the same code replaced the Valve cover, after there was no issues. Yesterday saw I had CEL and I was throwing P0174 code and there is a similar vacuum leak sound coming from under the hood but the Breather in the valve cover is not sucking in air. The Oil cap comes off but the engine starts to bog, what it could be now?
View 2 RepliesFord 6.0L Power Stroke Diesel :: Code P2623 For Stuck IPR Valve
My son is joining the site as we try to diagnose his first diesel. We checked fuel flow, and the bubble test. We held the valve down in the oil filter and watched it fill up in about 10 seconds and see it register on the dash gauge.
My Scan Gauge say it pushes 180 RPM while cranking, but it only gets about 225 on the ICP sensor and the IPR instantly maxes out at 84. It has thrown a code P2623 for a stuck IPR valve.
I hear a hiccup in the crank, but I'll let y'all listen and tell me. Will post YouTube link of it.
What are the chances of it being just a hole in the IPR screen or bad valve? I'm afraid we have a HP leak and need to do the air test to find it. I've never done that test and barely hear (rock concerts), my son hears but doesn't know what to listen for.

View 6 RepliesPontiac - Montana :: 2001 - Overheating / Low On Coolant
I have a 2001 Pontiac Montana that was overheating. It was low on coolant, and using coolant. I took it to a mechanic who checked it out and found exhaust gases in the coolant. He initially told me that it was a bad head gasket. After doing a bit of research, I am told that it could also be an intake manifold gasket. I know I am losing coolant, but I cannot tell where. I don't think it is going into the oil, as my oil level does not go up. I do not see coolant leaking below the vehicle, so perhaps it is going into the exhaust? Or leaking slowly on top of the engine where it is burned off before it can go on the ground.
Is there any test I can do to determine which gasket is bad before tearing into the vehicle? I thought about sending an oil sample off to determine if I am getting any coolant in the oil, but I don't know if that would be useful information at this point.
Pontiac - Montana :: 2006 - O2 Pre-heater Sensor Came On

My husband has been trying to google how to fix it and can't come up with anything. It doesn't even come up as to where the part is located.
