mark 39 Posted September 7, 2016 Share Posted September 7, 2016 If sensors ( CPS, TPS, O2, etc.) check OK (volts,ohms,...) and the MJ starts and runs good should any sensors be replaced on a time or mileage basis? Or does one wait for a part to fail when it's -20 and the snow is butt deep? Just trying to stay a step ahead of the electronics and the weather.

Eagle Posted September 7, 2016 Share Posted September 7, 2016 The oxygen sensor should be replaced approximately every 80,000 miles. The CPS does fail, but I don't recall there being a recommended replacement interval, and I've found that their life span varies greatly. Link to comment Share on other sites More sharing options...

Best preventative maintenance you can do is go to www.cruiser54.com and do Tips 1 through 5. Link to comment Share on other sites More sharing options...
