I got codes 232 and 113...checked fuel pressure..ok checked FPR..ok Did a reading on 02 sensor after warm .20mv? Not Good? Engine light comes on after it warms up in driveway. Been back and forth on this for 2 weeks, would anybody have a suggestion? Would like to thank everybody know for any clues. Thank You Richard. ps I replaced 02 about 150,000 miles ago. has 320.000 on it now.

 

I am assuming B230F engine, LH Bosch 2.4?

is the reading on the O2 sensor static or does it bounce between .1 and .9?

 

no, it stays at .19 to.20 mv. it is 2.4 Thank You

 

I had to replace plugs in it 2 days ago...fouled

 

Also took reading off green wire, I believe the 2 white wires are for heater.

 

sounds like its running really rich.
