The check engine light goes from steady to flashing when accelerating up a hill, even a small one. Took it to get code and it read P1633 which is the keep alive power voltage being too low. Would that cause the problem or is there another culprit. How do I fix this?
A flashing light indicates that the engine is misfiring enough to damage the catalytic converter, this needs attention ASAP, otherwise after the misfiring is repaired, you will be buying a new catalytic converter, the damage may have already been done. as for the p1633 has the battery run low and you had to jump it off, or recharge the battery?
A flashing light means its bad,you are damaging your converter,$$$ check and make sure alternator is not over charing.check for good battery conn.also check for good computer connections,could be faulty powertrain control module (pcm).
