New concern \"Service Engine Soon\" Light.For a 2004 DTS through over 111k mile now, recent stabilizer steering pillar change, brand-new plugs, recent oil adjust etc., once the \"Service Engine Soon\" light continues to be on, the manual says mostly to examine for fuel changes which could affect the light remaining on. Having none, just how do you get the light turn off without an high-quality dealer probe.
Read the sticky thread \"how to traction codes.\" that will also tell you what\"s resulting in the irradiate to go on, which could be for hundreds or thousands of reasons besides changing fuel.

Your Cadillac is equipped to provide you the actual diagnostic trouble codes (DTCs) the are bring about that organization light to come on without the must go to a dealer or mechanic. Review this \"sticky\" about reading the codes:www.barisalcity.org/forums/cadil...ncluding-1985/138257-how-pull-codes-dtcs.htmlWrite lock down, look increase the title for each one & then come back here & perform them. Then us can assist answer your trouble with specificity.
Have adhered to 70cougar\"s instructions and also have just one existing (Active) code, the rest were history. The active/current code was PCM P0410 i beg your pardon is for the Powertrain Codes, an additional Air Injection (AIR) System. After reading them, ns cleared all codes; and, the reset the \"Service Engine Soon\" light too. What follow-up might it use if the light comes ago on?

Have complied with 70cougar\"s instructions and have just one current (Active) code, the rest were history. The active/current password was PCM P0410 which is for the Powertrain Codes, secondary Air Injection (AIR) System. After analysis them, ns cleared all codes; and, that reset the \"Service Engine Soon\" light too. What follow-up can it use if the light comes back on?
The AIR device uses a compressor, valves and also piping to supply new air come the exhaust manifolds during cold beginning in bespeak to quickly light turn off the cat. The system is emissions and also engine administration sensitive, and every time it falls short to pass startup experimentation it will set the light and also code.Your vehicle probably has the compressor top top the level inside the LF fenderwell liner. The device tends come ingest splash water i beg your pardon freezes (corrodes) the compressor. It\"s a 3 hour DIY solve with the front finish up on jackstands. Many, many threads posted on this for Deville, Seville, and Eldorado. If you\"re no a gearhead it\"s a day at the dealer and also $450 - $600.BTW - Welcome board !!:welcome:

Welcome come the forum. Submariner409, who is one of our Caddy gurus here, has given you some good advice. You deserve to do a search on threads looking for \"Ranger\". The is an additional one of our gurus below who has actually done the AIR device compressor replacement.

Guru, no !!! Long-time gearhead. Done 3 Cadillac Northstar wait pumps, among other Northstar/chassis stuff. What i know around Cadillacs is zippo - engines..... Various story.Get this straight: There space a dozen or so regular, serious, knowlegdable contributors to these Seville/Eldorado/Deville/Northstar threads: their experience covers a many problems, but not all - by any type of means. You read the threads, you take the advice, and you try the fix. It\"s all a shooting in the dark - lacking hands-on diagnosis we\"re all flying blind. Statistically the deal with works - yet if it doesn\"t it\"s no one\"s fault; hard to kind out a valve tick on the internet...........:wisdom:
This is something brand-new to me I never knew about this, one airpump to aid out cold starts renders sense i guess, well ns guess you find out something brand-new everyday, also the older males like sub huh?

The an initial A.I.R. (Air Injection Reactor) pumps to be the lousy \"smog pumps\" the the so late 60\"s. A belt moved vane pump which constantly supplied air to every 8 exhaust ports in bespeak to continue burning any type of excess fuel. There to be no catalytic converters then. Countless variations on the layout since. Today\"s cats room efficient, so the takes just a short shot of fresh air to raise the (cold start) exhaust temperature sufficient to irradiate it off. When the cat is lit, it keeps on generating that own heat - there\"s a lot of energy wasted in petrol combustion. What comes the end of a modern-day cat attached to a mechanically great engine is around 100% water vapor and also inert gas.
The AIR mechanism uses a compressor, valves and piping to supply new air come the exhaust manifolds during cold starts in bespeak to easily light turn off the cat. The mechanism is emissions and also engine administration sensitive, and every time it stops working to pass startup testing it will collection the light and code.Your auto probably has actually the compressor top top the flat inside the LF fenderwell liner. The system tends to ingest splash water i m sorry freezes (corrodes) the compressor. It\"s a 3 hour DIY deal with with the front end up top top jackstands.

Have recurring reappearances of present PCM P0410 code. Took car to refer Oil because that check/fix. They stated there\"s one more TSB for a PCM software application update which might fix; prior to they replace any kind of parts - the course, lock don\"t have actually the capacity to do software update. Is this for real? Anyone recognize if Auto Zone can fix? Shouldn\"t Cadillac have sent me a recall notice if over there is a recall because that the PCM?
Have repeated reappearances of current PCM P0410 code. Took vehicle to to express Oil for check/fix.

Is this because that real? Anyone recognize if Auto Zone have the right to fix? Shouldn\"t Cadillac have actually sent me a recall notification if over there is a recall for the PCM?
The only people who deserve to confirm or deny the there\"s a recall because that a PCM update is a Cadillac dealer. Take it your auto and/or VIN come a organization writer top top a quiet Tuesday or Wednesday afternoon and also ask for a printout of the GM service/recall history database for her car. (Used to be dubbed \"GM VIS\") This does not require any kind of diagnosis or labor occupational - every the info is in ~ the business writer\"s fingertips and also it\"s in the (password) public domain.FWIW, \"Express Oil\" ??? for Cadillac repairs you\"re top top thin ice cream - likewise at AZ.
