Vacuum drops when the EGR opens, and the EGR only operates when driving. Even with the IDS it wasn't so obvious to see, and it is a very short timeframe. Personal I would focus on getting the vacuum right, then see if the issue still persist, and go from there.

 

I tested the Actuator for the Bypass Valve. It will not hold a vacuum. I also tested the line going into the actuator. When it's connected I checked the vacuum for the line going to the MAP sensor. It reads 12 in. Hg. When I take the reading fome the line going to the Actuator it reads 17.5 - 18 in Hg. so it is definitely the Actuator. Now I need to get the Part.

I need to get a Part number for just the actuator can anyone help? The valve shows up evertime I do a check for Part Number. Also is there a download for the partslist? I didn't find it on the JTIS.

Thanks!!!!

 

As it turns out this is a dealer only Part (NCC7703AC) at a cost of $175.89 form the nearest Jag dealership

 

There has been long time since any replies.
The egr in my 1995 xj6 4.0l x300 has a egr temp sensor that actuates the egr valve thru ecu and mine ic bad giving misfires and carbon buildup on plugs and o2 sensors. It runs good for about 8 miles then gives hicups and stalls and goes into limp mode. The sensor is open circuit about 1.2 meg ohms. Ordered an egr temp sensor they are not cheap. Lowest price about $!49.99

 

Hi what do you mean Don't try to start with a booster, you will fry the electronics.. Just wanted to know in case.

 

Hi Hazmat1075,

This thread has had no activity since 2013. Check your Driver's Handbook and Vehicle Care manuals for details on jump-starting your car.

Regarding the admonition against using a "booster" to jump-start a Jaguar, I believe the manual is referring to the self-contained battery-pack or capacitor style emergency jump-starting units carried by tow-truck drivers and other service personnel. However, I have a professional battery-pack unit that works fine on Jaguars. It's the JNC Air 1700 Amp JUMP n Carry and also includes an air compressor for inflating tires. It has "smart" circuitry to protect from reversed cables, over-voltage, etc. I have used it on many Jaguars with no problems, but your mileage may vary.

Cheers,

Don
