XK and XK8 Oxygen sensor codes and guide

Here is a guide for those Oxygen sensor codes on your Jaguar XK and XK8, it includes original part numbers, links and location in the car.

These codes:  P0131, P0132, P0133, P0135, P0136, P0138, P0141, P0151, P0152, P0153, P0155, P0156, P0158, P0161, are caused when the computer sees something wrong with the oxygen sensor circuits. Even though it could technically be bad wires or a bad computer, 99.9% of the time the cause is a bad oxygen sensor. Now which oxygen sensor is the next question, here is a guide.

For the location you should know:
  • Bank 1 is always the right side of the car.
  • Bank 2 is always the left side of the car
  • Sensor 1 is before the catalytic converter
  • Sensor 2 is right at the cener of the catalytic converter

  1. Hello, what do your error codes refer to? E.g. on a 2002 XK8 P1646 refers to Bank2 Sensor1 (Upper) and P1647 refers to Bank1 Sensor2 (Upper). I am unclear what a P0161 is.
