P0014 is likely a camshaft solenoid valve, the p0449 is likely a evap vent valve or wiring, and a p1400 (sorry for this one) is likely a cylinder head. based on the codes you asked you have the 4.2l L6 motor.

check airflo sensor or potentometer,throttle pos sensor; if revs are to low when turning the wheel the power steering pump will draw power from engine, causing your other problems

SOURCE: P0300 code reading on Chevy aveo. Engine light

Pull out your spark plugs. Change them if dirty. There might be a problem with the fuel trim, thats causing spark plug to foul up prematurely. A stucked open EGR valve can also cause a multiple mispfire code(P0300) but then it would be accompanied by an EGR code(P402) which means excessive flow detected. Anyways if was indeed a fouled up spark plug change them as well as the air filter.

You need to check the cam phazer and see if it's damaged. Lots of the time it leaks oil into the connector and messes up the wires. Also I've seen the oil control screens come out of the phazer and go into the engine, which will also set the coeds. If I were you I'd pull the phazer out and see if all 3 of the oil control screens are there. My bet is one will be missing. Make sure to change the oil too. You may get lucky and it will have made it to the oil pan? Other wise I wouldn't worry too much about it. Most of the time it will not cause any engine problems. Good luck, oh and you do have to pull the power steering pump off to get the phazer out. But you can just take the bolts out for the pump and let it fall down so you can get the phazer out!

I have a 2006 Saab 97x 4.2i, check engine light is on the the codes that came up are p0014, and p1400. Can anyone tell me the problems


Please follow the link for info you requested on P0014
http://www.autocodes.com/p0014_saab.html

P1400 Saab
When you check engine light came on code P1400 the reason should be Engine Light ON (or Service Engine Soon Warning Light). However Saab manufacturer may have a different definition for the P1400 OBD-II Diagnostic Powertrain (P) Trouble Code. So you should chech it on our car models.
Saab P1400 Possible Solution : The crankshaft sensor signals the fuel injection computer or the ignition control when the cylinders are firing. This causes the ignition coil to provide a spark and the injector to inject fuel into each cylinder at the right time.If either sensor isn't working correctly, the car will run rough and the engine will be less efficient. In later car models, the car's computer can usually keep the vehicle running, but the engine warning light on the dashboard goes on to warn the driver.

2001 Volvo V70 XC won't pass state emissions! P0014 and P0172 codes kept registering, and the check engine light appeared intermittently. The Emissions print out said "Not Ready". Last week, engine...


You need a repair shop to drive the vehicle with a professional
scan tool, for at least 25 miles

That way all the Emissions Monitors will run clear

If you fail to do that,your guaranteed to fail inspection

If any codes come back,then the vehicle has to be component
test & repaired

It sounds as though there was some pushing & poking, done by
I assume, a shop & parts changed,tested or in need of replacing,
who knows

You also will have freeze frame data at the time the codes are set,
to help with the diagnoses,IF-- you have a good shop to work on it,
so far that doesn't appear to be the case

I don't buy your hopeful rational --IF-- the oil has not been changed
(often)over the life of the motor,wrong oil used or the cam actuators
have failed,as is sort of where all this conversation has gone or
explained to you

If the cam timing is not correct,then yes, the oxygen sensor codes
may set- BUT- I don't buy the fact they go away & never come back

We could be here a long time,so I suggest you keep your line of
questions going at a repair shop. Their not wrong or far off,you just
need to understand how things work together in a motor or maybe
not play well with other parts under certain conditions

You fuel filter may have go to the end of it's life and will need to be replaced. Start with the simple and replace the fuel filter, the filter should be replaced every 15,000 miles or once a year to ensure your fuel system is running 100%. the Aveo fuel- filter is located passenger-side rear, in front of the rear tire. Good luck and start with this, keep me posted and Auto Zone can scan your car for the DTC code that your check engine light indicates there is an issue and the fuel filter can be bought there and they can give you the step by step instructions to replacing the filter.

Engine light on 2002 Explorer. engine code P1400


This may have to do with a bad wiring. Check all the wiring associated with EGR operation. Whenever a computer throws a code about high or low circuit voltage, it is usually attributed to abnormal wiring.
