hello speeders ..

after replacing the spark plugs , fix a leak behind the TB and install new exhaust
.. the car was fine in normal driveing but the idel was not steady , it was reve and set to 1700 RPM and after i put the gear in D it back normal ... or when i switched odd the A/c it reve to 1700 rpm !!!

when i ran the car hard it looks like am running 1 Cylinder car , boost never reach .1bar !!!!! i Switched the car off and back on .. boost came but slowley !!! after a min it never boost !!!

i checked with the cable .. here are the codes :

1- P2201
throuttle/pedal postion sensor "A" circuilt low value below
lower limit value


2-P2100
throuttle actuater controll motor circuilt / open implausible signal


3-P1115
throuttle adjusting unite adapt canceled due to environ condit
value below lower limt value

4-P0705
transmssion range sensor "A" circuilt


5-7516
engine purge fan



what do you think ??


thanks alot ..

 

i suggest to take back ur car to stock level because all of these defaults is from tuning :S btw am a big fan of ur car i always see u on youtube hope everything will get better soon..

 

thanks alot , but it was fine before replacing the plugs ..

 

update :
just let the dealer checked my car and they said its look like my turbos faild !!! What made ​​me wonder that when i switch the car off and back on and run hard ,,
it boost but very slowly and hard to reach .7 bar ,, after a min it never boost more than .1bar !!

what do you think ??

is my turbos faild ? or its TB issue ??? or what ???

 

If the turbos would have died, they will not boost and then wont boost.

The TPS = throttle position fault may cause the loss in boost pressure.

First get the throttle faults fixed. If the throttle does not open 100 %, boost may not come as well.

Second make a leak test. There may be a leak caused during spark plug change.

Third, put a set of different plugs. Your new plugs may be damaged as well. This is the least likely chance.

 

UPDATE :

the dealer checked everythings and data log the car by PIWIS !!
they found that the pedal is opening 100% but the throuttle is only opening 20% !!!!!!!!! they changed the pedal with new one but problem still there

the fault which appeard fast in the piwis is the

1- P2201
throuttle/pedal postion sensor "A" circuilt low value below
lower limit value

they said it may be the DME !!!!

 

Good luck.

 

Do you have agency power TB/Plenum? If you do go back to OEM and see if problem goes
away.

 

dealer will install new TB !
Will update you soon

 

sounds like a throttle body leak/failure. Check your electrical connections/plugs to make sure they did not get tweaked

 

will see what the dealer can do ...

 

update .. dealership replaced the TB and replaced the pedal postion sensor !!!! problem still there , TB is only opening 20% under full throttle
they think that it maybe the ecu need to be replaced !!!!

# the same day i was in the garage changing the plugs , the car did not start because the battrey died so we charged it normally ... is that couse ecu damage ?


thanks

 

Most likely fried ECU. Have the dealer reprogram a new one would be the next step, I hope you get this sorted out.

 

will check them .. thanks bro

 

UPDATE :


after dealeship told me that i should have new DME ,and many tuners confirmed me i taked the car back home and decied to fix it later , afrer 15 mins driving in this condtions i tried to active the cruise control but the green light did not apear , so i said it should be from the dme cuz all this throttle wiring connected which each others !!! after that i sweitched the car off than sweitched it on , quickly i turned the cruise control on , so the green light apeared in the dash , i drove the car hard and the throttle worked 100% , car is fine, i drove the car for 1 hour and everythings ran fine !!!!!!!!! once i sweitched the cruise control off it never back on except if i sweitched the car off than quickly turn cruise it on !!! at least now i can drive the car



still not sure if its the DME !!!!
