MIL on

[henrym3]

Fault Codes:-P0150  P0174  P1161. Confident I have no air leaks, no exhaust leaks, fuel pressure is good, injectors are clean and working as should. Have run live data and bank 2 pre cat o2 sensor just isn't switching. Have sent for two Bosch o2 sensors, there are cheaper but assuming these have been in since new, 134k is not a bad return. When they arrive and are fitted I'll update, although don't hold your breath I've just done the old back in.

Hope the back gets well soon, have had rods in mine to keep spine straight!!!
My mil lights go on and off, reset them and they are ok for a few starts and then on it comes again.
Check the sensor connections by the sensor,1 of mine was disconnected.
Common fault with lpg.

Even at my age I should have known better and not just trusted the diagnostics, didn't actually get in there and check the connections, am hoping I haven't spent £84 on two new sensors when all I have to do is push the plug back in the hole. If that's the case I'll have to give myself some serious verbal abuse.

sensors are by the exhaust down pipes .

Done the o2 sensors today, was reasonably confident when I took them out, bank 1 nice grey colour, bank 2 sooty and black. New ones in, running sweet as a nut, no MIL. Also fitted new heater valves as wasn't ever getting more than mildly warm air, have had them in the boot for about 2 months, finally realised they would work better in the engine compartment. Tomorrow is new adjustable rear upper control arms.
