Re: Check Engine Light
I show the following for a P2098:
- Faulty Heated Oxygen Sensor
- Heated Oxygen Sensor harness is open or shorted
- Heated Oxygen Sensor circuit poor electrical connection
- Exhaust leaks
- Contaminated Heated Oxygen Sensor

but again I'd just select the O2 sensor page on my cell phone and monitor them while driving. You have seen the first page before but my display is best with six parameters so I have several pages. This is the O2 sensor and fuel trim page.
The 1x1 and 2x1 (lead bank 1 and bank 2) are transitioning but the secondary sensors (1x2 & 2x2) are both reading mid scale right where they are supposed to be.
Key is they should both be between ,5 and .6 anything greater or less would mean something is wonkey but monitoring these while fully wamed up is the only way to diagnose the problem. Anything else is just throwing parts at it. (/rant)
Unfortunately too many mechs and including some really good ones have trouble using proper instrumentation.
