#1 of 41 4Runner VSC trac, check engine light
Jun 27, 2007 (8:34 pm)
I have a 2003 4Runner with about 50k miles. All at one time, the check engine, VSC Trac and Trac Off lights all came on at one time. the car seems to drive fine. Do I need to get it serviced? Anyone else come across this?

We have the same exact problem with our 2002 with 52K miles. It happened to us on a road trip to the mountains from the beach last week. The problem seems to re-set itself after a while but then yesterday it came back on again. I think it is problem a sensor but would like to know which one and where it is located on the 4Runner.

I had the same thing on my 2004 4Runner at just 2800 miles. I took it back to the dealer under warranty. Looking at my invoice, regarding the check engine light, the tech notes say:
OL2 sensor heater control circuit low.
Wiring harness to 02 sensor shorted to body.
Repair wiring harness.
Regarding the VSC and Trac Light:
Decel Sensor undone.
Recalibrated decel sensor.
I hope this helps.

I had the same problem w/ my 03 after disconnecting the neg. wire to the battery to clean up. Both lights turned off after driving around for one day. However, the automatic roll down for the rear window doesn't seem to work anymore. Any suggestions? Thanks.

I have a 2006 with 20k on it. I had the check engine light VSC and traction control lights come on. The dealership tells me that computer code read when hooked up to the computer it says that the O2 sensor in the catalytic converter is bad. Toyota will not replace just the sensor. So they replaced the catalytic converter. That was a week ago. The lights came back on this week and a new cat was installed today. Hopefully this time it works cause I'm tired of going to the dealership.

Hi, I'm having a problem similar to yours. Did this fix your problem. I don't want to have to get a catalytic converter if i don't have to . sheila

By replacing the converter did it work?? I'm afraid we'll replace it and it won't solve the problem. sheila

Hi everyone. Numerous folks including myself have had the VSC issue, but not all of us had the same fix. It's best to let your dealer diagnose and repair IMO. It could get very expensive swapping parts unnecessarily.
