Service engine soon light on 2003 Saturn Vue

I believe those are misfire codes on your cylinders. Tune up may be needed.

for the engine light to come on there will be codes stored
It is that the mechanic is not using the correct scanner with the right protocol installed to read them

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.

The CEL (Check Engine Light) will not go out until you hook up a OBD II scanner to your vehicle and erase the code. If it comes back again after you erase it than either the original problem still exists or you have a new problem. You can go to your local AutoZone store and they can hook up a scanner and erase your code for free.

Not sure, I would try with an OBDII scanner. Available at autoparts stores or online at JCwhitney. Good luck.

The car computer has detected a malfunction. You need a tester that wiil give you the OBD2 code corresponding to the malfunction.

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.

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.

I have a 2003 saturn vue which repeatedly gave me the P0128 code. I replaced the water pump, and ultimately had to replace the thermostat. The water pump is a $40 part, the thermostat is a $25 part. Problem is that its a 4 hour job by chilton timeframe. If you have the know how you can do it yourself on a saturday afternoon, however if your not familiar with playin with a Saturn, better take it to a professional.

Its on the drivers side of the engine below the intake manifold. Why do you want to replace it? I have worked with the VUE since day one and I have yet to see a bad coolant temp sensor. If you are having trouble with the engine temperature or the amount of heat in the car a very common cause is the thermostat sticking open and not alowing the engine to reach operating temperature. The most common telltale to this condition is usually the service engine soon light is on with a p0128 code stored in the PCM.
