Question about Jaguar XJ6

1 Answer

I have a 1993 Jaguar XJ6 and can a bad O2 sensor cause the idle speed control valve not work properly causing a bad idle? Then because of the bad idle can it make the throttle position sensor to also ack up making the car tell the transmission to go into limp home mode?

    Did that yesterday and I also took the Mass airflow sensor off and cleaned that out. I first did the Idle speed control sensor and then started it up and the light was on still and then did the Mass airflow sensor and the started it up and the light was off. The tranny light as been intermittened so I don't know if that did anything yet. I will be changing the valve cover gasket and o2 sensor this weekend. I am hopeing this will be all I need to do.

    I did that yesterday. Afterwards I plugged the battery back in and started it up and the tranny light was still on. Then I pulled off the mass airflow sensor and that was clean so I put it back in and plugged the battery back in and started it up and the light was off. The tranny light is intermittened so I don't know if anything I did solved my problem. This weekend I am putting on a new valve cover gasket and O2 sensor. I am hoping this will solve the problem. As I am kind of sure that the idle problem is what is causing my ecu to tell the tcu to go into limp home mode. Does that sound right?

I have a 1990 Jaguar Sovereign, 98,000 miles. The problem I'm having is the engine starts and runs, but it lopes at idle and runs rough, seems to be running too rich. I was getting fault codes 44, 37,...


I would change the air filter and clean the fine mesh covering the air flow control unit.
Make sure the connections are good as the sensor screen is tied to the O2 sensor. A new O2 sensor and dirty screen would give you poor fuel burning as the air fuel mix would be bad, and the O2 sensor would read the need for more fuel.......poor economy and running rough as it would not be clean burning.

Car wont start fault code 47. how to fix? 1993 XJ6


Fuel Fail 47 Idle speed control valve - coil 2: Open or short circuit.

This code 47 is signaling a malfunction that has occurred within the Idle speed control device. the code is saying that the circuit is inoperable at this time and you will need to service it or replace the entire device.

This is basically A computer-controlled air bypass valve located in the throttle body. It helps control idle speeds by allowing air to bypass the throttle plates as to increase the idle speed.



please rate and have agreat weekend:)

2001 Jaguar XJ8 Idles rough while sitting


o2 sensors often cause a rough idle at stand still. Previously my xj8 had crank case ventilation (pvc valve essentially) issues that caused the check engine w/ restricted performance. I noticed a severe drop in gas mileage as well. Jaguar dealer fixed my problems in a few hours and it was surprisingly cheap. Its worth taking it to advanced or auto zone to see what the computer says. Then decide if you want to shell out for a dealer fix or if you can tackle it yourself. BTW, just to justify myself this is my third jaguar. I have a '94 xj6 with a chevy 350 inside it, previously owned a 95 XJ6 and currently have the xj8. They are wonderful cars if you can put up with their rough times.

I cant remember what I had replaced about 5-6 months ago, seems like it was a sensor. My 1993 Ford Explorer is not running or idling at normal speed. When I pull up to stop it is like it stays engaged and...


listen for a hissing noise(vacuum leak around the pcv elbows or upper intake gaskets) this will cause a high idle set off lean codes which will say bad o2 sensors alson check idle air control valve which is located by throtlle body this will stick causing the vehichle to not run at idle sometimes taking it off and cleaning the carbon buildup out will fix the problem use some break cleaner
