Help with Tech Codes for 1997 Boxster

--------------------------------------------------------------------------------

I recently "inhereted a 1997 Boxster and a project car.

I am getting the following Techs Codes.

P1117 O2 sensor heater behind cat, bank1

P1121 O2 sensor heater behind cat, bank 2

P0160 O2 sensor CYL 4-6 behind cat

P0153 O2 sensor CYL 4-6 ageing, ahead of cat........

Does this mean I need to replace all the O2 Sensors.

I am a newbie and really need help......

P1117 - Oxygen sensor heating 1 behind catalytic converter – below lower threshold

P1121 - Oxygen sensor heating 2 behind catalytic converter – below lower threshold

P0160 - Oxygen Sensor After Catalytic Converter (Cylinders 4 - 6) - Interruption of Signal

P0153 - Aging of Oxygen Sensor Ahead of Catalytic Converter (Cylinders 4 - 6) - Below Lower Limit

P1117 and P1121 say the O2 (after cat) sensor heaters are not heating. Very odd to have this on both at the same time. I would have a good look at the wiring and connectors.

P0160 and P0153 are one sensor before the cat and one after - again very odd as this would say both are bad.

Again could be a wiring harness issue or a bad DME.

Is this a US car? Any other visible issues with the car?

Does it run/idle properly?
