....but not really .....now i have ur attention for a few seconds i have just done a ecu test on my car my96uk and it has come up with a falt code 45 (4 normal flashes 5 fast ones) does anyone know what this is??? in idiot terms thanks

45 is Pressure Sensor.

thanks i found it was a pressure senser but dont know which one???

AFAIK it'll be the MAP sensor

how do you do an ecu test? and how many codes are there and how do you find out what they mean? i also have a 96ukturbo...

i used this http://www.saxonfields.freeserve.co....iag%20Page.htm

If you have a code 45 it could either the Map Sensor or the Pressure Exchange Solenoid

The map sensor is to the left of the pressure exchange solenoid and the boost control solenoid is directly below the pressure exchange solenoid

thanks for that delboy do u think this would course it to over boost??

no but if you clean out the boost control solenoid with some brake cleaner that may help.

the BCS is the one under the pressure exchange solenoid in the pic, yours should have pipes on it but the one in the pic doesn't.

If it is overboosting due to the pressure exhange solenoid or the map sensor it would most likely be caused by split/damaged pipe from the manifold to them preventing the ECU seeing the pressure at the manifold.
Its more likely to be what Jonny has said as the code 45 will be given if the boost solenoid fails to control the pressure reaching the turbo actuator causing overboost.
If you connect the green plugs together and switch on the ignition the test mode sequence will be initiated which pulses the boost solenoid - while the solenoid is pulsing spray (as above) brake cleaner into the solenoid ports. Once complete reset the ECU as per Saxonfields site then test the car again

dellboy......jonny i owe u both a pint just been in garage for the last hour cleaned the boost solenoid out with some carb cleaner about 4 times did the reset taken the car back out and its all gravy boosting a treat holding 15 psi bang on the dot right down the rev range i am a very happy boy again thanks lads

Delboy2

If its boosting to 15psig it has either been 'tweaked' or there is still a problem as the standard boost for a UK96 is 11.47psig

does the boost solenoid have a pipe on the bottom of it?

the reason i ask is there is a restrictor in that pipe to help with boost control, if its missing it will cause the problem you are seeing.

scoobyjohn2000

little tweaks not just uped boost ....yes it does have the pipe on the bottom i have been and had a look(in my jim-jams) and it doesnt go anywhere just hanging there where does it go.....but the car is running perfect now????

that pipe should go to the bottom of the resinator box, the big black thing in the middle of the inlet pipe.

its most likely that the plastic nipple it atatches to has snapped off.

it would be a good idea to block the hole in the resinator box with something like a self tapping screw to stop it sucking in air after the maf sensor (not good).
