Hello all,
we have a 1994 Chrysler Concorde 3.3 and we had the check engine light come on. We took it to auto zone and had them do the check on it. The man that worked their gave us the only code that came up as 32 and said it was most likely a loose or bad wire or hose or the fuel filter. He said the other numbers of 12 and 55 were normal for our car. so the test read 12-32-55. The car runs great and we have had no problems only when we start it some times it takes 1-2 times for it to kick over. We had the starter checked and its fine. It is not making any noises, or sounds, no smoke or odor. Nothing weird at all. Does the filter need to be replaced or does it sound like something more serious.

Code 12 is loss of battery voltage within the last 50 ignition cycles. Code 32 is a problem with the EGR system.
(Exhaust Gas Recirculation). This is part of the emissions control system. It (the EGR valve) is designed to introduce inert exhaust gases (@ cruise speeds) into the combution chamber to lower combustion temperatures, helping to eliminate Nitrogens of Oxide (the major contributor of smog). At the same time, it reduces engine spark knock, again, by lowering combustion temps. You've probably had a car that would ping under acceleration, but if you put in premium gas, it would stop pinging. Higher octane fuel burns cooler than low octane, there again, lowering combustion temps. With all that said....unless your car is pinging under acceleration, you probably wouldn't know that the EGR was not opening. Now...just because you come up with an EGR code, that doesn't mean that the valve is bad. Could be a plugged passageway, solenoid, valve, ect. At this point, I'd try opening the valve while idling. This can be done with a vacuum pump (if this is a vacuum operated valve) or, if the opening under the valve is large enough, it can be opened with a finger. The engine should at least stumble, or even die when opened at idle. If it doesn't, more than likely, the passageway is plugged. Code 55 is 'end of test'.
