Possible lead wire for the fan shorting out. These problems may or may not be related. As the first contributor said, there might be a wiring problem in the fan switch to the fan motor circuit. Look for a wire rubbing on something else and look for the insulation on the wire to be damaged. Or the switch itself may be bad. I've seen them fail in the shorted (always closed) mode which will make the fan run all the time. This is probably not good on the fan motor as they are not meant to be used continuously. I can't recall right now what that switch looks like, but if you can get the wiring plug off the back of the switch and can get to the terminals that it plugs onto, you can put an ohm meter across the terminals. (do this with the engine off and stone cold) If the needle deflects, the switch is probably shorted (IE; bad) and needs to be replaced. OR, you can just try to CAREFULLY unplug the fan from the switch while the engine is running and the fan is running. If the fan stops, you can pretty much conclude the same thing...bad switch. NOTE: I don't really recommend this procedure. Fans can hurt you! Try to do this from UNDER the car if you can, so you can keep your fingers and clothing ETC away from the spinning fan. Also, this test presumes that the fan is still running all of the time. As to the Check Engine Light, be sure your fuel tank cap is real tight. If it's loose, it can cause the CEL to come on. Failing that, take the car to Auto Zone or Checker or wherever and have them put a code checker on the car's computer. They usually do this for free! It should give you some idea why the light is on.
If the AC is on constantly, the fan will be on constantly. If that's not it, it mught be the fan relay or the temperature sensor.
A 2001 Pontiac Sunfire 2.2 engine is a zero tolerance engine which will suffer catastrophic damage should the timing system fail. Because of the tight tolerances inside the engine, even being out of alignment a fraction of a second can cause the valves to slam into the pistons.
This is an indication that there is not sufficient oil in the engine ! Driving could cause the engine to cease, in the worst case it would then be scrap.
No, not unless you got some bad fuel with moisture in it.
THATS usally cause by the engine using oil-because of bad oil rings etc.
Engine is running extremely rich.
check if your battery is low than usual ..might be alternator problem
The most likely cause of this problem is a faulty engine coolant temprature sensor It will send a fault code to the ECU which will then illuminate the engine management light. It will also send false information to the ECU making the ECU believe that the engine is hot this will result in the cooling fans running constantly or coolant leakage.
If the engine was severely overheated, yes that can cause engine failure.If the engine was severely overheated, yes that can cause engine failure.
running with out engine oil
If the engine is not noisy then you have pressure. The cause is probably a failed oil pressure switch.
Overheating an engine can cause the engine to see up resulting in a complete engine failure. Overheating the engine can cause the head gasket to fail.
The most common cause of engine lockup is a lack of oil. Also, an engine overheating from lack of coolant can cause an engine to lock up.
feeds no coolant to your engine, then air gets into your engine which will cause it to seize up and shut down, car will constantly shut off when temperature gets to high(dosent take long at all). will blow your gaskets and engine this way
The v6 engines have valves burn out constantly, which will cause both the damaged cylinder and the one across from it to misfire.
Mechanical breakdown of the engine can sometime cause transmission delay in the engine.
A faulty temperature sensor can cause the ECm to think your engine is overheating, this turning the heat light on constantly. You should make sure that your engine isn't in fact overheating though.
yes this will cause engine to run hot
No, low gas cannot cause a Check Engine light to turn on. There would have to be a problem within the engine or the engine wiring for that light to come on.
A loose engine mount would not normally cause the engine to fall out because each car has several motor mounts. A loose mount could cause the motor to be off of balance.
No, a rusted flywheel will not cause the engine not to turn over.
no oil in engine or water in radiator will cause engine to seriously o/heat! and eventually seize! major engine damage!!
Not having one, will allow particles in and effect your engine and cause damage and cause your engine to stop running. It can also be dangerous and cause an engine fire.
you need to tune the carburettor
Yes, sometimes a faulty ignition switch can cause the engine to not fire. Also, a bad spark park can the engine to not fire.
