1999 3.2 xj8 p1647.
The last time I had upstream O2 sensor problems, the engine management light stayed on until they were changed for new ones, then all as well.
My recent purchase shows a P1647 code but I don't get the check engine light coming on.
This model's dash lights are different to my 2002 model 4.0 Sovereign, as the 2002 has a engine shaped RED light. Whereas the 1999 has the words CHECK ENGINE in Orange, which goes out when the engine is started.
I still have the P1647 sensor code, but no lights on the 1999 XJ8.
Do I have a problem with the sensor? If so, can I prove it first without replacing the sensor????
Thanks Bill W
