Vsc & Engine Light.

[Mike Hartland]

Whilst parking 60 miles from home yesterday the VSC, Trac Off & Engine lights came on and the "CHECK VSC" message came up. i managed to safely get home without further trouble.

Looking at various forums, including our American counterparts, this could be for a variety of reasons - apart from a brake problem - including ill fitting filler caps and O2 sensor problems. I'm not particularly technical, so I have no way of obtaining any codes that might indicate the problem, without booking myself into a dealer.

My questions are -

1. If it could be a fuel problem, is this perhaps due to me adding some Redex to the current tankful of Super Unleaded fuel? (I've not added it to this car before so I thought it might be time)

2. If the problem were to sort itself out, will the lights clear of their own accord, or do they need resetting at a dealer?

Before I forget, I have checked the filler cap and that seems to be sitting fine.

Thanks in advance

Mike

Hi Mike

Normally if a problem clears itself the light will only go out after three journeys.

To get the error codes read you should be able to take it to any competent mechanic, it doesn't need to be a Lexus dealer.

Update - As hoped the error lights have gone off. I guess it was the O2 sensors that were affected. The moral seems to be - don't go adding Redex to Super unleaded fuel.
