Yeah NCH you're right....where have I been???? Haa haa here in Australia that's where. Only got the truck last year, and the 1st thing we did was buy 2 CPS and put one in straight after we got the fault code that there was something wrong. Turns out it was not the problem but we left the new one in and there is a spare in the glove box. I think they must be from the "good batch" because we haven't had a problem with them.
