Disconnect your battery. touch the neg. and positive cables together for a second. let it sit for at least an hour. that should reset everything. as far as reading codes you would need a scanner. on OBD-1 cars you could use a paper clip and flash the codes. but on OBD-II you need a scanner

Hi, depending on what the problem was, it may take a day or 2 of driving for the code to clear. If it doesn't clear on it's own, odds are the issue was not completely fixed. You can always have the codes cleared with a scanner. Most parts chains will do this for free. However, the light will come back on until the problem is resolved. If you can tell me the code you had and what was done to correct it, I can advise you on why the light might remain on.
Thanks for using FixYa.
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.
Start with the simple and replace your fuel filter, air filter and clean your MAF sensor. You can buy and MAF sensor cleaner at Auto Zone and the fuel filter also. While your there Auto Zone can scan your Saturn for any DTC codes that my be causing your engine performance issues, Auto Zone scan free of charge and if there is any DTC codes. They can give you the information to what needs to be done to get your Saturn running 100% again soon.
Thank you for using fixya and good luck. Keep me posted.
This code is set when there is a variance in speed from the transmission input and output shafts. It can be a simple sensor issue or a more complex internal problem. There are several recalls for VUE transmissions but I do not think yours falls under this problem. Yours sounds more like an internal belt issue which Saturn has a technical bulletin for as shown below. This usually requires replacement of the case cover and filter and sometimes the belt depending on the damage. This is the bulletin that has to do with your code; Bulletin No.: 04-07-30-024E Date: June 09, 2006 TECHNICAL Subject: No Movement in Drive or Reverse with or without DTC P0741, P0742, P0841, P1756, P1758, or P1882 (Replace Case Cover Assembly and Filter) Models: 2002 Saturn VUE - Retrofitted with a 2003 or 2004 VT25E (VTi) transaxle (RPO M16/M75) 2003-2004 Saturn ION 2003-2005 Saturn VUEwith VT25E (VTi) transaxle (RPO M16/M75) Supercede: This bulletin is being revised to add additional Correction information. Please discard Corporate Bulletin Number 04-07-30-024D (Section 07 - Transmission/Transaxle). Condition Some customers may comment on the vehicle not moving in the "D" (Drive) or "R" (Reverse) gear selection positions. In many cases, the transaxle will also produce an audible grind or whine noise when attempting to operate in drive or reverse. The Service Engine Soon (SES) telltale may be illuminated with DTCs P0741, P0742, P0841, P1756, P1758, or P1882 set. Cause This condition may occur when the VT25E transaxle belt has malfunctioned.
Code P0378 means, DTC P0378 Timing Reference High Resolution Signal B Intermittent/Erratic Pulses. DTC stands for Diagnostic Trouble Code. I highly doubt it has anything to do with the actual timing of the engine. Chances are there is a problem with the camshaft / crankshaft sensor (which measure engine timing). Without a scanner that shows individual sensor inputs there's no real way to know. I would try replacing the sensors (they aren't incredibly expensive), this should take care of the problem and if not the only other option is to take it into a repair facility.
