Is this a emission related repair that is part of my 7 year 70k emission warranty.


thanks

If you're talking about the federal emissions warranty, then no. My dealer specifically checked on this part when mine went out, and it was not covered. The more I've asked about it, I find out that it sounds like the only things covered under the 8/80 federal emissions warranty are pretty much catalytic converters and ECU units and their software.

It's an easy 30 minute fix, and there's an updated part that should be used. I haven't had any problems in the 6 months since I replaced mine. Dealer list on the part is $360, but they can be found for less. It looks like they're going for about $273 on Amazon and $220 on ebay right now. I lucked out and got my hands on one from Amazon for $136. I put up a DIY on the replacement at: http://www.cruzetalk.com/forum/169-...matter-sensor-exhaust-particulate-sensor.html

I saw that and that what I am trying to get answers for if it's not covered then I'll fix it but if it is covered then let them take care of it I don't need a 150.00 telling me I need a sensor that I already know about

If I may add,

Clear the code and see if it resets before throwing parts at it......many of these have thrown a code for no reason......very sensative setup.

Nope it's not covered just left the dealer. And I was able to hook up my scanner yesterday but now it will not let me connect. When it did let me I reset it but immediately came back with the power reduced warning

I should've gone into more detail......

I recommend a battery negative cable removal for ten minutes to reboot the entire system.....often a single code clear will create 'implausable' information from other sensors.

Plan on resetting the clock.....often the radio stations will hold.

Ok took out the sensor cleaned it reinstalled my issue of the scanner was a chip that was loose. Ok so I'm still stuck because I have the filter is full keep driving light on with the reduced power. You think it will still do a regeneration. Or am I stuck with going to gm with a manual regeneration

Unable to answer......get up on the highway and ring its neck I guess.

If it includes, "Keep driving," it seems like that would mean you could be able to drive the re-gen out, otherwise why would it instruct you to eep driving, right? I think there is another message that goes along with the fatally-full filter that requires the manual re-gen. I think the message is mentioned in one of @diesel's posts. Never dealt with this problem myself, though, so I'm just trying to remember his account of it. My P24c6 code was set for like 1500 miles or more before I had the time to narrow down the problem and obtain the sensor, and it never prevented normal operation, reduced power, or did anything other than light the CEL.

Ok drove at 2500rpm 70mph for 40 miles. Got to work rescan new and the code is back for the sensor so it needs to go. But I this sensor triggering the filter full issue. I need to do some more reading. In the mean time look for the best pricing for this sensor

@mr overkill Be careful about driving with the DPF full message. You can get the DPF too full and they will not be able to do a manual regen and you will have to replace it. I do not think the DPF full message is related to the particulate matter sensor message.

Mine always went immediately from the "Keep driving" message to the "power reduced" message. I know why - it was because my soot grams jumped from 22 to 35 immediately (I documented that elsewhere). Once you are over 32 grams of soot, you can only get a manual regen. Soot accumulates rapidly once you are over 32 grams as well.
@revjpeterson When you had the issue, did you get a DPF full message? I don't think you did.

Nope. I drove 1500 miles with p24c6, and re-gens occurred normally without issue. Unless there is an update to the ECM software since mine, a problem with the particulate matter sensor shouldn't interfere with any other emissions components.

Ok so here is the scoop I was given. This sensor has the ability to "override" the other sensors readings so there I a chance that I won't need a manual regeneration I was told install the sensor. Clear it and see and if I need a regeneration it's going to cost me 80.00 to 130.00

Keep us posted. I hate to sound negative, but I think your DPF is indeed full. I hope I am wrong about this. And your manual regen is quite a bit cheaper than mine were!
