Archived from groups: alt>autos>jaguar (more info?)
my wife's 94 VDP posted code 37 "EGR solenoid". I changed the solenoid then
the car got worse. Wouldn't start cold then wouldn't run at any reasonable
speed, till it warmed up. I cleaned the fuel tank, changed the filter,
desoldered and resoldered the MAF. The car started right up and on the test
drive started acting up again( like it wasn't getting fuel). Got it back to
the garage and checked the code......37 came up again. Any ideas?
Thanks in advance,
Joe

Thank you. I'll check those things. Right now I'm leaning toward the MAF or
catalytic converter. I only worked on the MAF connector. I didn't change it.
While doing that I noticed one of the wires goes to the EGR solenoid, and
just sort of "put two and two together" Where did you get your info? That is
pretty detailed.
Thanks,
Joe

Here is the list of probables from the jag-lovers XJ40 book:
Possible faults:

- Blockage in EGR transfer pipe between egr valve and intake manifold,
- Blockage in intake manifold EGR adaptor port (90% of problems),
- Disconnected, leaking, blocked, pinched vacuum hose between,
- EGR valve and the egr vacuum solenoid,
- Defective EGR solenoid valve (stuck),
- Defective EGR valve,
- Defective egr temp sensor,
- Open or short in egr temp sensor wiring.

Most modern cars use exhaust gas into the intake tract to reduce combustion
temps and NOx because exhaust gas is inert. It has no fuel or oxygen.

The EGR system ONLY operates when the engine is up to temperature and the
engine is under light or moderate loads.

Now Gunner.
After all you ARE a Jag owner and like the rest of us you are not allowed
to read the instructions until you have broken it and all else fails!!!!

wakka wakka.
I just disconnected the cats and ruled that out. I trimmed the 'flared'
part off the EGR vacuum hose......no joy. I'll be playing hooky from work,
so I'll get into the guts of it tomorrow.
