2002 Saturn Vue V6 Loss of Power

My 2002 Saturn Vue currently has the service engine soon light that stays on. On occasion, the Reduced Power light comes on and it's like the Vue stalls out when this happens. I turn the car off, and then turn back on, and it's like nothing had happened. Is there a typical issue that occurs when this happens? The car seems to run fine otherwise.

    I have the same problem on a 2000 Saturn LS2. Is a revised throttle body/actuator an expensive fix?

  • tcpizzi Feb 19, 2009

    Same problem. No one knows how to fix it. I have 140,000 miles on the car and it has run great until recently. Will Saturn fix it?

    3 weeks ago timing chain went after reduced power light came on, dealer replaced the chain and then called me and told me the head was bad and valves. Cost me almost $3000! I drove away and service engine soon light came on, then reduced power light came on, took it back again and they claim code said sensor behind the converter was bad will cost about $260 to replace. Then they told me the serpintine belt and bearing for the pully needed to be replaced about $800. They should have checked the head before replacing the chain! Now the vue runs real rough, they tell me it is like an old person and with age things go wrong! I hope GM goes bankrupt they deserve it!!!

    I have the same problem with my 2002 VUE. I've been waiting since December for a throttle body, but the date of the part arrival keeps changing. It was February, then April, now it's May 15! Does Saturn ever have the intention of manufacturing a new part? I think they are stringing me along until GM figures out what to do with the company. Until now - I've never had a problem with this vehicle and loved it.

Yup. The throttle body connectors have a history of failing on these cars. Replace the throttle body and the wire connectors that go to it, and you're back in business. Not terribly difficult and you can get the parts from any dealer. Saturn actually has a bulletin out on this problem but they won't cover it unless you're under warranty - no recall for this.

    I had the same problem and the parts were around $500.

    I have the same EXACT problem with my 2002 Vue and its been like this for over 2 years now, my friend told me that there are 2 different parts to the throttle body, do you happen to know which one we should replace?!

  • cgrizzel Sep 07, 2011

    My vehicle was actually shutting itself down. The part was on backorder at the time, so I put a posting on craigslist that I needed a throttle body, and someone had one. They took it off of a bad motor (that had a different issue). My local mechanic replaced the part, and fixed the problem. I would recommend taking yours to a mechanic to have it diagnosed.

Saturn has a revised thorttle body/actuator assembly and what looks like some wiring revisions for the connector.

Posted on Jan 04, 2009

Testimonial: "Wanted to follow up to let you know it was the throttle body. Got it replaced (had to find a used one, as they were on backorder), and works great!"

  • slifersrus3 Dec 26, 2010

    Where do you get the parts?

  • cgrizzel Sep 07, 2011

    Hoping you found a part by now. They were on backorder at the time with no end in sight, so I got one off of a used motor.

How do i reset the oil light on a 03 saturn vue? i did the turn the key and press the gas peddle 3 times and that didn't work.

The procedure you used is for the 2006 > Vue, and will not work on your 2003. For the 2002-2005 Saturn Vue V4 or V6 - Under the hood you will see a black fuse box behind the battery. Open it up and you will see a red button, it is small and looks like a fuse but on the top it will say Oil-Res. Turn on the ignition & press and hold that button for about 10 seconds. You may want to have a friend sit in the driver's seat and watch for the indicator to start flashing, which indicates you've activated the reset. Turn off the ignition and that will reset the Oil light.

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.

Reduced power for real!!!!

There is a fault somewhere on the vehicle which has triggered the engine management system to limit engine power to minimize damage.If you have breakdown cover and live in the Uk then call them.You need a computerised diagnosis of the engine.If you live locally then mail me at [email protected] and I will assist you further.

Reduced power light came on

reduced power messge is not caused by oil pressure. i assume this a 3.0L v6. this engine has a electronic throttle body which is a electric motor that operates the throttle plate that takes the place of a throttle cable. in cold weather the pcv (positive crankcase venelation) system accumulates moisture that will form on the throttle plate, in cold weather the water freezes and causes throttle plate to stick. when the ecm detects any malfunction whithin the throttle control circuit it is put in to reduced power mode that limits throttle position. usually resets after ign. is cycled. there is a service bullitin to re-position pcv hose behind throttle plate to reduce moisture bulid-up on throttle plate. your saturn dealer can perform this service.

Your vehicle’s computer system has self-testing capability. When the computer senses that there is a problem with some of the components it stores the correspondent trouble code(s) in its memory and lights up the "Check Engine" or "Service Engine Soon" light to tell you that there is a problem and you will need to have the car diagnosed and repaired.
