Yeah, I still miss it even though it still haunts me.

I'm back in the game, though. I agreed to take my grandfather's '95 Deville Councours when he passed away on 12/19. It needed to get out of his name to keep from complicating the will. It has no real value to the average joe. It's been sitting in his basement for 2 years. It ran great when he parked it there, and it looks like it will clean up nice. I need it for the winter. The Trans Am, as predicted, has proven to be less than capable in the bad weather.

He also had a green on green '79 Fleetwood Broughm. It's really rough though - no one wanted it.

Re: PCM P0410 Secondary Air Injection System Malfunction

I really want a Brougham of that vintage but the green kills it for me in any condition. Plus I don't really want a project, I want a nice clean car.

It was a nice clean car. He parked it in one of those portable outdoor garages and forgot about it. Evidently it gets REALLY humid in those things. Lots of mold and mildew. Pretty much a basket case now.

That's a shame. I love those even if it is green.

Yeah, he got too old to drive it. It was beautiful in the day. Metallic green and green leather (if you're into that sort of thing).

The '95 Deville is that blue/green color. It has about a 1/4" coating of dust on it, but it'll clean up. He had just had the TCC solenoid fixed when he parked it, too. One less headache (though the trans curiously puked all the fluid out as it sat).

Here's the poor thing as it sits in his basement:


I hope to get it out of there within the next couple of weeks.

I don't even know what that is - I'll have to look it up. I thought he said it was a Concours. Is a Touring Sedan a version of the Concours?

Jim

EDIT: Duh. I get it. As in DTS. As far as I know, the Concours was the DTS equivalent in 1995. It has the higher output engine, I know that for sure.

Re: PCM P0410 Secondary Air Injection System Malfunction

I'm not sure the Concours was the DTS equivalent. I think there was still a DTS but I guess the Concours also had the emblem in the grille. That's why I said that.

Yeah the Concours is a nice car. I think that was a model where they gave you the HP but kept everything else luxury. I don't know a ton about them but they're a nice looking car. They also have partial wheel cover on the rear wheel, right. Like a baby sender skirt.

They're sharp. clean her up and love her.

It was a great looking car at one point in time. Still has the wheel covers on the rear wheels. Vanity mirrors for the rear seat passengers. Unfortunately it doesn't have heated seats, which is one thing I really miss about my old DTS. I'll have to put a remote starter in this one to warm it up.

Re: PCM P0410 Secondary Air Injection System Malfunction

Yeah, funny I was just talking to someone else about that. I wonder why they didn't have heated seats in those. Unless it was a costly option and few people got it.

You could get them, but it must be very rare. In searching for pics of '95s I came across a Concours at a used car dealer that had heated seats.

Re: PCM P0410 Secondary Air Injection System Malfunction

No, especially not in the warm weather, but the code and/or system fault will fail an emissions test.

Your car - the compressor is on the frame flat indide and in front of the LF wheel - behind the plastic liner. There's a solenoid and vacuum switch on the right (rear) side of the engine, at the fuel rail. That solenoid ports actuating vacuum to two AIR valves - the one next to the solenoid, the other just next to the "lower" radiator hose on the driver's side.

Check the electrical connectors and the vacuum lines. Any broken vacuum line/elbow can be replaced with a length of proper sized vacuum tubing from any parts store.

Re: PCM P0410 Secondary Air Injection System Malfunction

My 2001 Eldorado got a SES while we were on vacation in Holland Michigan. The dealer up there told us we needed a new intake boot as the old one was cracked. We had them replace it and it fixed the problem. The next day the light came back on and we took it back and they said the code P0410 meant the secondary air pump was seized and needed replaced. When I got home I replaced it as it just unbolts and pulls straight down from under the bumper cover. It just took 10 minutes and a $150 dollar pump. I got the code reset and it came on the next day again. So I came on here and read a post from Submariner mentioning a vacuum hose problem. I checked and the dealer either forgot or accidentally pulled it off and it wasn't replaced. I put it back on and don't expect anymore problems.
Thanks Submariner. You don't know me but your expertise solved my problem and saved me buying 2 air shutoff valves at approx $50 each.

Re: PCM P0410 Secondary Air Injection System Malfunction

I have an 01 Deville with the same code. I replaced the air pump, fuse and the valves are good and vacuume hoses are good. What else could cause this code?

Re: PCM P0410 Secondary Air Injection System Malfunction

It looks like your multiple duplicate posts, 3 minutes apart, auto-merged. You need only post a question one time.

Go back through this entire old thread, then look through the pages of Discussions, Item Specific: Cadillac Tech Tips for threads on the AIR system. Then, if still no joy, try to Google "cadillac forums 2001 deville secondary air system".

Next to the #1 (right) rear bank AIR valve there is a solenoid control valve with 3 vacuum lines attached. Trace out those lines and make sure they are not leaking/broken. Any of those plastic lines and rubber connectors may be replaced with a proper length of correct sized vacuum tubing from the Help! racks at any large parts store or NAPA.

Re: PCM P0410 Secondary Air Injection System Malfunction

Will the pump only come on if the car is cold, if so does it get information form the engine temp or is there a sensor? I have checked all the wires , if you are wondering; the small brown goes to computer, the small red goes the fuse box ign1 10 amp fuse, One of the large red wires go to the 50 amp fuse and the other goes to the pump.

I have replaced the pump. When i start the car with a multi meter connected to the plug (pump disconnected) it reads up to 15 Volts for a period then drops to zero (as expected). When I connect the pump and connect a multi meter is has no voltage and the pump does not come on. I have checked the pump and it is operational. I'm getting punchy. Thanks for being a great source of info!
