SOURCE: saturn vue 2002 aed v6 not passing inspection test

sounds like a dirty mass air flow sensor.if you have in deed replaced it i would check the voltage going to the sensor.perhaps its a faulty connection between the power controle module and the sensor socket.if that dosent work i have a few more tricks to try get back to me and i will help further. poppinwheelies@sbcglobal.net

SOURCE: 04 Sedona 3.5 cyl #2 misfire replaced coil,back again 5 mos later

How many miles on the plugs and wires? Misfire can be caused by either plugs or wires, after that check the injector for that cylinder. Let me know what u find. Curt

Sounds like it may be running a bit lean - do basic checks for air leaks in the induction system (such as leaking manifold gasket, loose hose fittings to air flow sensor etc).
Condition of HT leads also worth a check.

P0172 - System Too Rich (Bank 1)
Basically this means that an oxygen sensor in bank 1 detected a rich condition (too little oxygen in the exhaust). On V6/V8/V10 engines, Bank 1 is the side of the engine that has cylinder #1.

Note: This DTC is very similar to P0175, and in fact your vehicle may show both codes at the same time.

Symptoms: You will more than likely not notice any drivability problems, although there may be symptoms such as a misfire. This is the next code explained.

Causes: A code P0172 may mean that one or more of the following has happened:
* The MAF (Mass Air Flow) Sensor is dirty or faulty. Note: The use of "oiled" air filters can cause the MAF to become dirty if the filter is over-oiled. There is also an issue with some vehicles where the MAF sensors leak the silicone potting material used to protect the circuitry.
* There could be a vacuum leak.
* There could be a fuel pressure or delivery problem

Possible solutions include:
* Inspect all vacuum and PCV hoses, replace if necessary
* Cleanthe MAF sensor. Consult your service manual for it's location if you need help. I find it's best to take it off and spray it with electronics cleaner or brake cleaner. Make sure you are careful not to damage the MAF sensor, and make sure it's dry before reinstalling
* Inspect fuel lines for cracks, leaks, or pinches
* Check the fuel pressure at the fuel rail
* Check the fuel injectors, they may be dirty. Use fuel injector cleaner or get them professionally cleaned/replaced.
* Check for an exhaust leak before the first oxygen sensor (this is unlikely to cause the problem, but it is possible)


P0301 - Cylinder 1 One Misfire Detected
A P0301 code means that the the car's computer has detected that one of the engine's cylinders is not firing properly. In this case it's cylinder #1.

Symptoms may include:
* the engine may be harder to start
* the engine may stumble / stumble, and/or hesitate
* other symptoms may also be present

Causes: A code P0301 may mean that one or more of the following has happened:
* Faulty spark plug or wire
* Faulty coil (pack)
* Faulty oxygen sensor(s)
* Faulty fuel injector
* Burned exhaust valve
* Faulty catalytic converter(s)
* Running out of fuel
* Poor compression
* Defective computer

Possible Solutions:
* If there are no symptoms, the simplest thing to do is to reset the code and see if it comes back.
* If there are symptoms such as the engine is stumbling or hesitating, check all wiring and connectors that lead to the cylinders (i.e. spark plugs). Depending on how long the ignition components have been in the car, it may be a good idea to replace them as part of your regular maintenance schedule. I would suggest spark plugs, spark plug wires, distributor cap, and rotor (if applicable). Otherwise, check the coils (a.k.a. coil packs). In some cases, the catalytic converter has gone bad. If you smell rotten eggs in the exhaust, your cat converter needs to be replaced. I've also heard in other cases the problems were faulty fuel injectors.


Keep in mind that the "misfiring" are not only for bad O2 sensors, check the other componentes that I tell you before.

Keep us updated.

Check your coils on the top of each plug if it Is an ecotech. I had this same issue with my 2004 Saturn Vue. Replaced the coil pack n I was rolling down the road again

Mis fire code po300 po68


300 is random misfire and 306 is cylinder #6, I would check the coil pack on #6. If it has separate coils per cyliner, swap the coil, see if the misfire goes to that cylinder. If it does replace the coil.
If it has three coil packs you can still swap the coils. If that doesn't fix your problem, then you will have to check the injector with an ohm meter. resistance between the prongs should be between 11 to 15 ohms. check another injector and they should be relatively close. Let me know
Good luck

2009 saturn aura random misfire cyl 1 codes p0014,p0201,p0300


okay there are a few things that need to be checked here, seems like you were testing the wrong things, lets start with the po300, this code is for a misfire a random one which means any cylinder at a certain time has misfired which is due to the next two codes listed, the po014 which is the exhasut camshaft postion sensor system performance and the po201 injecotr control circuit for cylinder #1.

Have the injector ohm ed and the connection and wiring checked, this problem may be a bad injector or wiring to cyl # 1 and the cam sensor needs to be tested also on bank 1exhaust side. good day

2002 saturn vue cylinder 1,3,5 misfiring when swapped coil pack it went away now cyl 2,6 misfiring.


having PO 304 = Misfire cylinder 4,PO 306 = Misfire cylinder 6, as I read above you have done the most. The thing that you have missed is to check whether the Catalytic Converter is faulty or not. To get an idea check whether you have a smell like rotten eggs at the end of the exhaust,you start having problems with cat and needs replacement. My advice before you go for a cat replacement is good to visit an MOT center and check your emissions and then you decide,

Ok i got a 2002 saturn vue..code was saying bank 1 bank 2 running lean..the vue runs perfect ,sometime at park it would idle hi.anyways i have replaced the mass air flow unit..turn off light,comes back on...


I had exactly the same problem .Mine was corrected with replacing the O2 sensors .The sensors cost less than $30 each but cost about 20 mins labor per sensor .So if you got an honest mechanic the total cost will be around $130 .
