Hi All. The Engine management light on my 2.1 v6 x type will not stay off. All Lambda sensors renewed and voltages checked.


Gets the same smog test readings when light is on as it does off and passes no problem.


Car runs fantastically well with a lovely quiet engine. But that bloody light is driving me nuts. Have wiggled the wires to see if its just a break somewhere but nope. Someone suggested disconnecting ecu and then reconnecting in case it's simply a bad or dirty connection on the plug?


Thanks in advance for any advice. I am hoping to sell this car to get a newer model and the engine light is proving to be a hindrance.

 

What code numbers are you getting?

 

Had p1647 which indicated sensors. Replaced them all as a precaution. But still the engine light comes back and the code comes back too.

 

Wrong sensors, bad wiring, etc. Maybe beyond your DIY skills.

Sad to say I gave up on it. Even taking it to main Jaguar dealer didn't find out why!. So I have now got rid and am no longer a Jaguar owner. Maybe again one day but the two I have had recently have driven me up the wall so a cooling off period is definitely required!
