1995 Supra EGR Diagnostic???

johnlijo · 02-26-2006, 04:07 AM

I got the check engine light checked out by the dealership and they said the egr switch and the egr gasket needed to be replaced.

So I replaced:

1)EGR Switch
2)EGR Gasket

Reset the check engine light by unhooking the batter for 10mins. It cleared but the light came back again.

So then I replaced:

3)EGR Valve

Light came back again.

Is there something I'm doing wrong???

When the light came back on, did you have it diagnosed??

I have seen the light come back on many vehicles, and it was a different code. It just happens. You fix the original problem, then another pops up. Hey...its not a perfect system. Man made it, its gonna break !!

Jump the connectors and count the flashes to find out which code(s) you have.
