2000 Boxster S with 60000 miles.

Got CEL. OBD II said P0154 and P1119.

Could someone please help me to check the code for me?

 

P0154 is "O2 Sensor Circuit No Activity Detected Bank 2 Sensor 1".

P1119: DTCs started with '1' are Power Train codes, Manufacture Controlled.

The Boxster Bentley shop manual has some (very little) info on this code, but it really maps to some internal Porsche code.

You might check the archives here and the tech site to see if there's a more detailed coverage of the '1' codes.

Also, it really really helps to make sense of the codes by having the ability to view ODB engine data (O2 sensor voltages, long term fuel trims to name two) as engine running. Sometimes one can figure out what's going on by this other info.

Sincerely,

Macster.

 

make sure the connectiono is clean and tight, then you need to check the wiring from the dme to the connector, if the wirings good you need to check output signal from dme. Then if all thats good you will need a new o2 sensor
