The thing is,back last year I did put my phone on charge in my car which is something I never do. Then within a day or two I had the cps issue. Go forward 12 months and the same thing has happened, put my phone on charge, and it appears the cps has been upset. Couple weeks ago When this issue appeared I unplugged the cps and plugged it straight back in and it's been good so far? Is it possible that the power socket could be effecting the cps somehow?
The short answer: it *shouldn't* be - at least, not the radio (i.e., phone) part of the equation. The chances of the phone being the problem are slim to the point that I wouldn't suspect it just yet.
The longer answer: there's a more likely a possibility that something in the electrical path between the phone charger and the CPS is causing the issue. Chargers aren't typically made to the most exacting standards, so it's possible that it's causing an issue further down the line that doesn't have any obvious or otherwise effects on the phone. More on that past the upcoming reply, but when you had this issue the first time, did it happen with exactly the same phone and charger?

Very strange. The power outlet has it's own direct lead. Battery, fuse, outlet.
This is pretty much my recollection of that circuit as well; it's always-on and directly-wired (i.e., no switches or relays) to the battery. Been a few years since I had to look at it closely, though.
There are two commonalities between the charger and the CPS that come immediately to mind here: the battery and the grounds. Make sure the battery is in good shape with decent terminals and that the main grounds (battery negative to inner fender; engine block to firewall) are also in good shape.
The next thing I'd try would be a different charger on the same phone, and (if unsuccessful) a completely different model of both phone and charger on the power outlet. Granted, this could cause the issue again, but it at least sounds as though you have a workaround for it if I've read things correctly.
From there, it's a little more involved. You'll have to check the wiring from both the power outlet and CPS for breaks / worn insulation. Make sure that if you find any they're not contacting the body.
Brainstorming................could the "radio waves" or whatever they are called, going through the air affect the CKP/CPS.
Well... While I wouldn't completely discount the possibility that the problem is being caused by the RF emissions coming from the phone, my gut feeling is that it's a fairly slim chance that that's the cause. While any wire (read: the leads to/from the CPS) can act as both a transmitting and receiving antenna, given the combination of low RF power output from the phone, the bands that it's likely operating within, and the general design of the electrical system in that regard, I would call it unlikely.
I know that if I have my cell (handy IIRC in Europe) near my monitor, it disturbs the monitor screen just before a call comes in.
They're only 'handies' in certain parts of Europe - in the English-speaking bits, we generally just refer to them as 'mobiles'
But yeah - while this is a good point, monitors are typically some of the most-susceptible devices to RF interference. Speakers are another one; you've probably heard the clicking / buzzing through them as well when a call is about to come in. The CPS is a totally different beast in terms of design compared to either of those, though, so it wouldn't really be expected to behave the same way.
