Just plugged in my OBDII reader Autel Maxiscan MS509 for the first time .

Its in Dutch language, but 6+2 codes are there.

I have no idea whats the list of codes means
But i try to search the forum also..

I have 8 codes ,and the car has ABS/TRAC light most of the time
When i start or drive the car.

And sometimes goes away when the car gets in second gear.
If it takes to Long to get into second gear the light also comes on.

A bump in the road or waiting in front of a Traffic light and the ABS/TRAC Comes on again ..

Also have had a few times restricted performance light after the engine mount broke .

Also a fuel smell somtimes and i cannot located where that comes from..

I have never seen that restricted performance light before the problems with The loose engine {the engine is tight now with new mounts}

I wanna have it fixed because it almost got me in allot danger when the Car Lost power on the freeway.

I have the codes here pictured
Sorry for the Dutch language on the pictures.

Can you guys please help me in the right Direction what could be the
Problems, think there are a few...

 

Roy,
p0105
Map sensor likely unplugged, check the little plastic tube is connected.
p0400
EGR valve issue, not plugged in? it connects to the lh exhaust manifold, it could have a leak...
p0430
catalyst below threshold - is it plugged in? B bank 2 h20s sensor
p1121
Here we go, this is a common fault now with the throttle position sensor wearing out, it has 2 tracks that are in constant contact with the ECM once the tracks wear, signal is lost and restricted performance activated. Since it didn't occur pre-wobbly engine check the connections before sending away to ASI for a rebuild, a new throttle is $2000, the part can be bought but second hand and prone to failure also.

p1601 I've no record for

p1646
fuel pump 2 relay malfunction - could be a failure, swap the relays to check or use a spare.

I think you've replaced the battery recently?
Of the codes above the only one that bothers me is the 1121 as it's a random bugger and not funny when it happens.

The rest, well ask the guy who fitted the engine mounts/subframe bushes to go over the connections.
Clear the codes once this work is carried out above to address each and see if they come back.

P1111 is a 'nothing code' the scan cannot complete because of the codes, when all is well this code turns to P1000 - all clear scan pass. We always have 1 code 1000 if there's no issues!

hope this helps, it's a sister car treat it well!

No Sean, you just reversed it. P1111 tests complete.

 

P1601 is ECM/TCM Serial Communication Error and will throw the check engine light.

 

Thank you very much Sean for input .

The MAF sensor connector was pulled of the MAF two times because of the broken Subframe mounts .

The engine moved to much and pulled of the MAF connector
After this i got all these random Restricted performance light and power loss car goes into limp mode ,when restart a few times it solves again.

I hope it didn,t brake a internal wire somewhere ,
And i will check again and clean the connector ,the connector clicks in the MAF and i plugged it in a few times maybe of the pins are bend and make bad contact i will check...

The MAP sensor ,when i locate it i will check the connections and vacuum hose .



Hope i find loose connections or hoses ,that would make it easy..

I wil check for the fuel pump relais in the trunk ,and switch them .
And see what happens.

And the TB sensor,worst case i try to get a second hand TB with low mileage And than i can send other the TB for repair ,i need my car...

Could it be a TB plug connection problem ?,can i pull the plugs on the TB And Check the pins without problems?

 

Before i can do anything i saw a coolant return hose {the small ones under the intercoolers}

When i touched it the plug on the coolant canister broke where the hose ends

Probably from earlier stress on that part its moves constantly when there is movement from the engine and it has not much flex ,got me stuck have to get that first it throws up coolant when i start...

Than i can work on all those .... codes .

 

Got a new coolant return hose today,
Noticed it was about an inch longer than the old one ,so it has More flex and less chance to break when the engine moves.

I switched the both fuel pump relais ,no noticeable difference but took all the relais in the trunk out and put them back again..

At first sight i could not find any loose connectors In the engine bay.

Found the rubber seal between the intake and the TB sitting not the way it should be so i put i a bit better in place on the TB didn,t take it of.

I gave it a hard reset took battery - lead of and contact on.

Next i started the car an got a constant Restricted Performance light

I took it for a drive and about 20 miles later i noticed the light was out and i got the Full power back ,drove more than 50 miles no light .

I know there probably still are a few codes ,havent checked that for now .

The ABS/TRAC still comes on when i wait for a red light or hit a bump Sometimes under breaking i feel a vibration in my brake pedal and the ABS/TRAC light Comes on driving constantly on the freeway ABS/TRAC it never comes up.

I,m not really worried about that ABS/TRAC because thats not such a hard fix

Its probably an ABS sensor/connection wire ,the module ,or the brakepump {there is allot of info for me on this forum for that to fix}

For now that i have no Resticted performance light on the dash and most important the Limp mode Did not came up,{for now}.

I kissed my steering wheel because my car lives and hope
They stay out Untill i have the time to give the cat the tlc that it needs regularly.

 

If you feel a vibration in the pedal and the abs light comes on under hard braking, that is the abs unit functioning to prevent lock up.

 

Thanks yes its not under hard breaking {i am no racer }i know how it shakes when the ABS comes on but only had that in the winter with the wide tires the ABS sleeps in the summer..

My symptons when you push the brake pedal ,there is a Very light vibration and then the ABS/TRAC light comes on .but thats not the thing that worries me....


Problem again this morning the car jumped into limp mode 4x in the first 15 minutes ,people were thinking i was playing with them
After a Few restarts it drives again like nothing happened.

Have not seen a reduced performance light anymore like before, but now the limp mode .

But this is the beginning ,if its the TB a second hand is about $500 and i can send my old for the new sensor and TB cleaning ,think thats what they do when i send the TB.

All these problems came right after the broken subframe V mounts
I have to get deeper in this

Because thats when i got the first Limp mode when i felt under braking how the V mount broke
and the car lifted and the engine pulled/broke hoses and MAF plug from there connections
So after reading the codes ,
thats the first things to check or have checked every hose/connection/

 

What are the codes now?

 

Will Get them asap ,still need the car daily, got several limp mode,s specially when the car is not fully warmed up

 

Just read the codes after several Limp mode,s .



P0102 MAF G70 Signal to Low
P0105 Sensor manifold /atmospheric pressure-G71 /F96 Malfunction
P0112 Temperature sensor For intake air G42 signal to low
P0332 knock sensor 2 -G66 Signal to low
P0400 EGR system Malfunction
P0430 Cilinder bank 2 cats system efficiency under threshold value
P1121 Code not found
P1642 Code not found
P1646 Code not found
P1601 Code not found

ACTIVE CODES

P1111 Code not found
P1646 Code not found

Need help..

 

If I had that many codes, I would be looking at the electrical distribution and ground connections, thinking there was low voltage due to poor connections. You have checked the battery voltage while turning the engine over, I assume, both on the battery posts and on the connecters.

 

+1

Codes are in JTIS, it's a free download...

 

Now months later and thousands of $$$ further nobody can fix it specialist break more than they fix


UNTIL someone fiddled around with the ABS wire/ and Plug on the module and the ABS TRAC STAB light and all the stupid Jaguar LIMP MODE goes out ,all this Sh..

problems prob has to do with the ABS pump module and the plug ,connectio problem ??when i take the plug of and on and start everything works !

no more lights on the display just like it used to be .but now it only works when the engine is warm ,

when it is cold and i accelerate ,the LIMP MODE GOES BACK ON ,when the engine is warm nothing happens ,

these Jag tech people are crazy making these cars so fragile ...i try to figure out what i can do first

open the plug on the ABS module and clean al the stupid pins maby change the whole module and ABS pump if that does not work i burn the car...

 

Hold on. Some of the ABS modules (usually fixed onto the ABS mass) - not made by Jaguar - have had dry solder joints. Moving the wires might also move the solder but the fix is to re-do the soldering.

These faults are common to many many cars from many makers since the fault is actually the dry joints from the supplying maker.

There are posts scattered all over the net you can read to confirm - with fixes!

Now... you'd hope every shop knows but they're only human and may not (plus it's not necessarily your car's issue).
