Note On Intermittents

WARNING: This page is about a different car, the 1990 Cadillac Seville and 1990 Cadillac Eldorado. However, it is still accessible from the selected car via links, so may be relevant.

If B337 shows as a history code, without other codes, check ignition feed, CPS ground, and data circuits for intermittent faults. If other codes are stored, refer to MULTIPLE INTERMITTENT CODES in this article.
