97 voyager - catalytic efficiency failure
OK, so the "service engine soon" idoit light came on. So I paid the
local Merchant’s Tire $98 just to tell me i have a catalytic efficiency failure. Now they want some $300 or $400 more to complete the diagnosis. I’m thinking they’ve gotta be kidding, right? 1) Is there some other way to find out what’s really wrong? 2) Is the car in any real serious trouble or is it just some nuissance thing? Thanks for any advice...

Report abuse: http://www.autoforumz.com/eform.php?p=626977 When the upstream 02 sensor and downstream 02 sensor start switching at the same rate, that is telling you that the catalytic converter is not working and replacement is the only fix. That is how the cat efficiency monitor works Glenn Beasley Chrysler Tech |

The funny thing was, this code isn't even in the table of the FSM! However, when the dealer read it with the scan tool, it said the issue was catcon efficiency not being in spec. Matt |

I found 72 via a Google search and it said it was catalytic convertor efficiency and this agreed with the scan tool at the dealer so I figured it was correct. And since replacing the converter, the MIL hasn't reactivated. Matt |

The flashing dash light gives me the codes: 12 - 33 - 72 - 55 - can anyone confirm what those codes mean? i.e. do they really tell us the cat. converter is dead and needs replacing? - how long can a drive this thing before it does serious damage or quits? thanks, Glen Flowers -- Posted using the http://www.autoforumz.com interface, at author's request Articles individually checked for conformance to usenet standards Topic URL: http://www.autoforumz.com/Chrysler-9...ict128570.html Visit Topic URL to contact author (reg. req'd).
