Question about 2003 Saturn VUE

2 Answers

I have a 2003 saturn vue 6 cylinder. my service engine soon light came on and my friend had a diagnostic tool and checked my computer and this code showed up, my friend reset it. it came back on after 12 days. my heater is working good and engine temp is normal. i have noticed that my fuel gage is not working properly..it doesn't go to full when i fill up, but i am still getting good gas mileage 19 mpg. want to know if i should rush out and get this fixed right away or could i just reset it again and again. the coolant level is normal...i was on the Jeep page so i found the saturn page and i am asking again for Saturn owners, thanks,

From the looks of it this is a very common problem with the 2002-2003 saturn vue. There was a Technical Service Bulletin from saturn about the problem, which means it happens alot but not quite enough to warrant a recall.

You need to replace your thermostat and it is a pain to do, the dealership will charge you about 2 hours flat rate to put it in.

Its not a huge deal to get it replaced right away, but the computer depends on the vehicle being a certain temperature and if it isn't then your performance/emissions will suffer.

SOURCE: p0128

the dash reading and what the power train control module see are different , also very short trips after engine start can set code , thermostat may be partially stuck open , very low coolant can cause code to set also

SOURCE: Saturn vue 2004 what is aECt connector and lines?

The ECT is the "Engine Coolant Temperature". There should be 2 sensors on the engine, one for the ecm (engine computer) and another one for the temp gauge on the dash. I dont have the info to tell you where they are, but near the thermostat housing and the cyl head is the logical place.

The service engine soon light will not be relate to the airbag light. You will need to have your obd3 Diagnostic Trouble Codes read Most auto parts stores will do this for you. This will also pinpoint the cause of your SES light. If your bags have not been deployed you can have the control module reset at www.myairbags.com for a reasonable price.

2003 saturn vue. replaced spark plugs and the


Did you use the recommended plugs or did you use a new style like E-3 or Bosch +4 or something similar. Sometimes using a plug other than the original type can cause problems. Check and make sure all the wires or plug connections to the plugs are secure. Check to see if a spark plug has a cracked insulator. If you used antiseize on the threads make sure none of it got on the spark plug electrode or it will missfire.

Hope these ideas help.

Service engine soon light, service light, reduce power etc.


It is most likely the Throttle Position Sensor has gone bad. But if the check engine light is on, the only way to tell exact problem, is to have a scanner placed on the vehicle to have the codes read.

Service engine soon light comes on and engine in vehicle begins to rattle and shake uncontrolably and service engine soon light blinks


The blinking light indicates a sevier miss fire. Get the codes scaned to determine which cylinders and we can go from there.
Auto Zone will scan codes free of charge.
Chances are you have an ignition coil or injector driver issue.
let me know.
