Diagnostic Aids
WARNING: This page is about a different car, the 1998 Cadillac Seville, 1998 Cadillac Eldorado, and 1998 Cadillac DeVille. However, it is still accessible from the selected car via links, so may be relevant.
Since this DTC can set under normal conditions, no diagnosis should be performed unless a driveability complaint is present. This DTC may also set if all 4 camshafts are off by one tooth (10 degrees BTDC), causing a severe driveability problem.
