Does anybody know if there is a replacement time line for replacing sensors on our mtrs, such as the IPR, or do we just wait till they fail? thanks for any info. Roy.
I dont specifically know of a replacement schedule for sensors ect. I just keep 2 extra cps in the glove box for when the need arises. I have 160k on my original cps so why change it till it goes.
I do carry a superchips code scanner, spare belt, alt. and starter with me. Guess I like to be prepared when I am in the middle of know where. Or at least be able to tell what the issue is hopefully. Hopefully others will chime in with more knowledge.
It’s more a luck of the draw than anything else. When I bought my truck new in December of 01, my CPS lasted about 6 months. I am now on the second one which has lasted 9 ½ years. Best thing is to keep a spare where you can readily access it if your truck suddenly dies a long way from home like mine did. If you get in the habit of replacing items that may eventually fail, you might as well buy a new truck and save yourself the time. The only problem is that a new truck may have more issues than the one you own. I keep a separate “travel box” with other items when I drive back to Wyoming from California every now and then. Most of the time, I am within a hundred miles or so from home so I just keep the essentials onboard on a daily basis.
The IPR is not a sensor it is a solenoid operated valve. You can just replace the solenoid if it fails, or you can rebuild the valve portion with kits available.
The above items are the most common items to go bad. The IPR and Fuel Pump are the two that will leave you stranded. ICP and EBP sensors can be unplugged and the engine will still run good.
Like the others have said. Having spares in the truck is the best option. I always buy new parts, then keep the old units as spares. As you see from prices, it is not real cheap to have a bunch of spares, but each part is far cheaper than being broke down somewhere you don't want to be stuck.
