Hi I have a 1998 Caravan with 117960 miles. The "Service Engine Soon"
light just came on yesterday, at about 10 to 20 miles less than stated
above. Before I go for the diagnostics somewhere, I read that certain
vehicles are programmed to have the SES light come on at a certain
mileage. Is mine one of them? The other obvious thing is I have a hole
in my muffler/exhaust system somewhere, that I plan on getting fixed
soon. It wasn't too bad yet the last couple of weeks, but is starting
to get a bit louder. Will the computer sense that? I just want a clue,
if possible, what I'm dealing to ruke out the above two things before
I start spending money on repairs. Thanks much. |

I found my answer, so no need to respond. With more Googling, I found
people were getting a free diagnostic at their local AutoZone stire,
so I tried that, and my local store diagnosed it for free with a
handheld scanner. It's an O2 sensor that's high on it's voltage. |

That's not a diagnosis, that's merely a trouble code extraction.
There are a number of causes for high O2 sensor voltage. >> Stay informed about: 98 Caravan Service Engine light - mileage or exhaust? |

Thanks. BTW, I just had a new muffler put on, and the SES light is no
longer on. >> Stay informed about: 98 Caravan Service Engine light - mileage or exhaust? |

I doubt that fixed it.
The muffler is too far from either O2 sensor to have an effect
and even if it weren't, an exhaust leak would drive the O2
voltage low, not high. >> Stay informed about: 98 Caravan Service Engine light - mileage or exhaust? |

Yep, I spoketh too soon. The SES light came back on today. Wonder why
it went off after they installed the muffler, it went off after
driving a mile out of the muffler shop, and stayed off two days, now
back on. Guess I'll have to replace that O2 sensor, or have somebody
look at it to see if something else is causing the sensor to run high.
Thanks. >> Stay informed about: 98 Caravan Service Engine light - mileage or exhaust? |
