They told me that this was nothing to worry about, that it was a common problem in Crossfires (which I have read quite a few postings about already), and I believe them in the sense that my car does run absolutely fine, however, it is extremely annoying and for a $15,000 car having to deal with the persistant annoyance of a check engine light gleeming at me is unacceptable.
To cut to the chase, I was told that it was 100% problem within the software itself and that they would get back to me when they were able to fix the problem. I am ready to take the problem into my own hands and need your help. Has anybody else had this problem and done anything to fix the problem? I heard about a case where somebody with an SLK had a p0410 and just needed to spray down the MAF... any suggestions??
Hi Arnotm1,
YES...But do not touch the MAF. It's not part of this problem.
This is the cheapest and most likely fix for the P04110 CEL...they replaced 4 other components on my crossfire...before we finally got it solved with this fix.
The little BLUE check valve #12 in the illustration is a known issue with the Secondary air injection system. It is prone to sticking closed. This check valve is between the vacuum control solenoid and the diverter valves which allow fresh air to flow to the exhaust. When this valve is stuck it can not open the diverters. This sets the P0410 code, due to the O2 sensors not seeing a change from the fresh air being injected. Hope this helps.
Part #05096374AA. Right (passenger) front corner of the engine, under the engine cover. Bright Blue valve in the vacuum hose. If you change it yourself pay close attention to the position of the arrow (molded into the plastic) it indicates direction of flow.
What is #19.. I hear a hissing sound coming from that pump.. Is that normal..
