Hi folks

I had engine light came on the other day and go off after bout 2 mins, so when got home I did a ecu check and codes 45 and 32 come up.

45 is the pressure exchange solenoid and 32 is the o2 sensor, but I replaced the o2 sensor bout 3 weeks ago ???? I checked the connection on the solenoid there ok so I cleaned it out with brake cleaner but it didn't fix it.

Is it just a case of replacing it ? and why is the o2 sensor coming up as faulty ? would fixing the solenoid get rid of the o2 code too???

anybody help ??

1. Map sensor
2. boost solenoid
3. pressure exchange solenoid

is this correct ? is it just the pressure echange solenoid that would cause code 45 to come up or could it be a fault will any of these ??

thanks white un

 

Don't worry about the o2 sensor i changed mine and did the ecu reset but that didn't get rid of the code, but it went after i had the battery off and hasn't come back since, to be honest i think the ecu and ecu reset has a mind of it's own when it wants to keep the codes lol

 

I hope you right mate ! lol ! need to sort the pressure exchange solenoid problem out thou !
Thanks White un

 

code 45 is the pressure sensor,is your car hitting fuel cut and not boosting well?,first you need to check the vac pipe from the fuel regulator as mine came off and gave me the same code,if that pipe comes off or is split that can kill your engine,
if you have no problem with the fuel reg pipe and you still get the code let me no cos i have a couple of the pressure sensors

 

No mate car is running fine, pipes looks all ok. would a faulty sensor give me fuel cut ? how much you want for one ?

Thanks White un

 

i know its stupid question have you rest the ecu as it might be a old code,your not getting any sharp drop in boost
with the window down and bonnet up turn ignition on and you should feel the solenoid click as you turn it on and off,does it do that
have you checked all the pipes are tight and not blocked
