A vaccume leak could cause that OR one of the hoses going 2 the gas evaperator canister OR a hose going 2 the Tank or filler neck.
The filler neck could be cracked at the tank
You may simply need the have the code reset. If, after being reset, the check engine light comes back on, then you have further problems.
Probably the filler neck is rusted through.I had the same problom on a 1996 Pontiac Grand AM.
Fixed the same on my Venture 2001 by changing the vacuam purge switch ...looks like a solenoid switch connected to and located near the vacuam canister ... easily remove.
Have vehicle scanned to determine the problem
It can be many things. Can be a blown head gasket, stuck thermostat, cooling fan not working properly, water pump problem, etc.
VTEC may or may not work when the check engine light is on. It depends on why the check engine light is one. If it is on because of a problem with the VTEC system, then, no, it will not work properly.
check the #18 fuse for the injector in the engine bay. My 2001 venture blows that fuse when the wipers are activated. Im in process of finding the problem.
Do you need to check two possibilites, one, check if the oil is from transmission or from the engine, if the oil is red,is from transmission and you need to replace radiator, if the oil if from the engine you got it a big problem, because the only way that the engine oil is inside the radiator is because the engine has a bad head gasket, that mean you need to repair the engine heads.
Have vehicle scanned to determine the problem and have codes cleared
Because the engine is not properly configured
It could be any number of problems. If you can hear the engine cranking but it doesn't start, you have a problem with either fuel delivery, ignition (spark) or compression. If you have all three functioning properly and the engine cranks, it will run. If you can't hear the starter turning the engine, it could be a bad connection, the starter, the neutral lockout switch or the keyswitch.
This could be a problem with the oil pump. Just because you have oil visible on the dipstick does not mean the oil is properly getting to the engine. Have the vehicle serviced as soon as possible to avoid engine damage.
it can be of all stupid things a improperly fasstened gas tank cap
The engine will run inefficiently.
Vacumn modulator could be at fault. In older cars both the transmission and the cruise control rely on engine vacumn to know what the engine is doing, if the vacumn strength is not properly relayed to these components then odd behiavior will result because the tranny and cruise control don't know what the engine is doing.
Problem with emission system or fuel cap not installed properly
I think that depends if you have a check engine light on because of it. If the speed sensor is not working properly, the engine will not use gasoline as efficiently so there may be an emission problem
If the check engine light is flashing off and on when the engine is running that means an engine cylinder(s) misfire has been detected . You need to have the vehicle scanned for any trouble codes to help diagnose and then repair the problem
The 1996-2006 Chevy Venture has a 3.4L V6 engine and requires 6 spark plugs.
The 3.4 litre V6 engine in a 2002 Chevrolet Venture has a timing CHAIN
Usually a problem in the emission control system or fuel cap not installed properly. Have vehicle scanned to determine the problem
The inspection light will come on when the engine is not operating properly. A check of the engine electronics is needed to find the problem that is turning the light on.
If you reset the computer then the Check Engine light comes back on, it just means that the problem still exists. You need to use a code scanner, find out what's wrong, fix the problem properly THEN see if the light comes back on. Often when the problem is properly repaired the light will go off by itself and you don't need to clear the code.
Most likely it is a problem with the gas cap itself. Make sure it is closed properly. Most likely it is a problem with the gas cap itself. Make sure it is closed properly.
there is actually no problem. it sputters because the engine has to start up and it may be the way you place the key inside the ignition. so don't worry because it isn't a big problem
possible due to Engine mounting problem or ECU is not responding properly. Pls. contact to your mechanic ASAP. Usman Ali
I have had this problem on a 1998 and 2000 Chevy Venture and it was due to the seal on the gas cap. It caused the sensor to remain on due to allowing too much oxygen into the mix. I had to take it to a dealer to reset get it reset. Hope that helps. My problem was the catalytic converter (around 150000 miles). I am one of those guys that hate bringing any problem I have with my vehicles to a dealer or a mechanic -- Period. If your check engine is on and will not go off bring it to AutoZone or Checker (CSK Auto) and use one of their 'free' scanner tools to read the codes off the van, find out was is wrong, reset the light and repair the problem. ___________________________________________________________________________ I had this problem recently on my 2001 venture. The problem was the bank one Ho2 sensor was bad. This triggers the check engine light. After replacing the sensor (which was about $68.00),The problem was gone . Just remember to clear the code.Edubs
