Question about 2001 Saturn SL

1 Answer

I have a 2001 Saturn SL1. While driving, the electrical seems to just shut down. No radio, dash lights, etc...for a few seconds, then it would come back on. Now when it does this, the car dies. I've got a trouble code for the egr valve. It's got a new gas cap, new alternator, and starter. The battery/alternator test says both are fine. Any thoughts?

    Well, in the end, I wound up having to replace the EGR Valve. Problem's fixed. Car's running great now.

    The keyed part, or the electrical switch inside? Everyone I've talked to (parts house wise) swears up and down I've got a microchipped key, but I don't. I've had replacement keys made, and that's what I use on it.

    The keyed part wont make the car shut off. If you gently turn the key, either way while the car is running see it it hiccups or shuts off. Your key is like anyother key, no chip. People at the parts store are not people you should be getting info from. Last week they were flippin burgers, this week they sell car parts from a computer screen. Talk to Dealer Personnel who are familiar with YOUR car.

    Well, scraped out the EGR valve, and got a diff code on the EGR valve. Sprayed out the EGR valve, and got yet another code about the EGR valve. Replaced the ECTS, and problems solved.

  • Ted Schore Sep 16, 2010

    Whats ECTS?

  • Ted Schore Sep 29, 2010

    ECT Sensor.... is the correct term. But thats not going to make the engine shut off along with the radio, dash lights. So what codes are you getting for the EGR valve? A bad valve could make the engine idle rough or stall at idle, but not shut off driving down the road.

  • Di Oct 03, 2010

    P0404 (?) was the most common code I got. I wound up replacing the EGR valve in the long run. After about 4 days of carefree, problem free driving, that code popped back up. So, I broke down, and just bought a new valve. (That's been 3 weeks ago roughly.) I also (about 4 days ago) found that my positive battery cable had corroded nearly all the way through, and have since then, fixed that.

SL1 wont start sometimes

Sounds stupid, but could be bad battery conection. The car gets enough amperage to run the acceseries but not enough amperage to start the car. Clean and tighten the terminals. It cost nothing and will eliminate these connections as the cause if the problem persits.

2002 Saturn SL1 - won't start, turn over, starts fine with jump

Have the alternator and battery checked. The battery may not be holding a charge. The alternator may not be charging the battery,it should put out between 14 and 15 volts,any less the alternator is bad.

"Service Engine Soon" warning light

The "service engine" light come on in about 80% of older cars quite frequently. Usually, it means nothing being related to some emissions component or similar. You can shut it of with a rented (for free,) tool at Autozone. The tool is a code-reader, and can also tell you what the specific cause is, as well as instruct the on-board computer to simply turn off the annoying light. Odds are it'll come back if you don't fix whatever trivial B.S. it is complaining about. Best advice: Unless it's something major, just live with it like everyone else. - Good Luck, John
