Code 54 problem on the st205 Options

[Craig]

right peeps i think i might of sourced the problem out with my low boost just latley for the people that have not read my last thread here is a quick run down.

first bought the car boost use to run at 1.2bar over time this as creeped off now the car boost's at 1.1bar but just l8ly the car as been playing up it will only boost to 0.5bar now when the car is cold it will boost at 1.1bar but once the car gets warm thats it she only boosts at 0.5bar.

now do u think its the code 54 that is playing my car up? if any one else as had this problem please tell me how u fixed it?


thank u craig

If you still have the CEL from the code 54 it will keep you in low boost mode
check to make sure ur IC water level is correct and the your pump is working.

To check the pump leave the car idling, walk around to the engine bay blip the throttle with ur hand and you should feel the pump to see if it turns on.

At an idle the pump will be off.

If that stuff doesnt work out for ya. you can just ground an ecu wire and the 54 goes away.

Good luck,
DEF

thanx for the quick reply m8 when u say u should feel the pump kick in were abouts should i be feeling m8? also if i have to ground the ecu i can do that through the level sensore switch cant i?

yes you should be able to get away with connecting the lever sensor together, if thats the problem. If the pump is faulty, that will throw a 54 as well.

Insted of feeling the pump. Open the IC fill cap let the car idle up to temperature. Then blip the throttle a few times and look to see if the fluid level goes up and down at the fill point of ur IC. If so the pump is working correctly.

Good luck,
Cheers

thanx for all the info guys and that other post is a vry good one ill try that ic thing l8r when i get in form work. ive read that the level sensore is vry sensitive? and ive noticed i could do with some water in the ic so maybe fingers crossed it might be the water level. once ive toped it up should i reset the ecu?

Yes, make sure you bleed the IC water lines.

[Insanity-74]

you dont need to bleed the intercooler lines as such....just top it up, take it for a short run then top it up again....that should be all you need to do

[Craig]

well guys i got home last night let the car cool down and toped the ic up reset the ecu and Wella BOOST IS BACK! WooooHooooo i think i worry to much! lol thanx for all the help guys. Also i did not relise untill i went to check for errore codes the car as a Apexi Ecu on it as well so it wont check for codes Bah! ahh well all i need to do now is that my dump valve sorted then the car should be runing 100% spot on again.

Thank u all again Craig!
