Sensor ?

[mark 39]

         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.     Mark

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.

This^^. And use only NGK or NTK oxygen sensors.
