newsance Posted November 22, 2006 Share Posted November 22, 2006 Ok. So I'm getting code 33 for both the ECU and TCU. My tach and fuel gauge also don't work, but the speedo DOES. Looking at posts here, it seemed clear cut that the VSS in the speedometer was bad, because according to some posts, that is ALWAYS the issue if the speedo is getting a signal. So I changed clusters and am having the exact same issue. No tach, VSS code, and no fuel gauge. What is funny is that as I was driving home from buying a new instrument panel, something happened and the tach, fuel gauge, and VSS started working (I know it started working because the CEL went out). Looking at schematics, it shows the tach and fuel gauge sharing the same ground, and I'm sure the VSS does too. BUT WHERE IS THE BODY GROUND? I'm sure this is the issue.

Legacy777 Posted November 25, 2006 Share Posted November 25, 2006 Do you have the schematics/diagrams? If so, find the page that has the combination meter, and look what pin its ground is, and trace it back to the chassis ground. I believe there is a section that shows the different chassis grounds. However the books may not tell you exactly which ground point each device grounds through. If that's the case, just find the wire, tap into it, and run a new ground lead to it.
