Please HELP!!!

I have a 99 UK spec Turbo it cuts out between 2500 and 3000 RPM an engine check light comes on if i hold throttle to the floor it bounces at 3200 rpm, if when moving i put full throttle its like hitting a brick wall. the problem is intermittent. I've just done a diagnosic check an it comes up code 45 which is Pressure Control Solenoid can any one tell me where to find it an if any one has any tips on what could be the problem please do post as this problem is driving me nuts.

i had a sim prob on my 99 turbo 2000, but didnt show an error code.

I changed the maf sensor and cleaned the boost solenoid,
im told that the maf sensor doesnt always show an error code when faulty.

When the car is idle, try disconnecting the maf sensor, if the engine cuts out staright away or coughs and splutters, then the maf sensor is ok.

When my did this with the faulty sensor, the engine just carried on running as if i hadnt even unplugged anything.

If the maf sensor is faulty, make sure you reset the ecu.


Just an idea, Im no pro.

Could be the MAF but if you are getting a fault code then I would start with this first.

bets thing to do is do an ECU reset and see if the fault exists afterwards. If it reappeards then the Idle sensor is faulty. The MAF test is also a good one but be sure to unplug the MAF when the car is up to temperature

i reset it the other day an it still came up with code 45 an if i'm right its the Pressure Sensor Duty Solenoid wat has this to do with idle sensor i'm puzzled. i'm goin to give it a clean if i can locate it and might as well clean the boast solenoid while i'm at it. i'll also check the maf to eliminate it. its doing my head in lol.

well its not the maf an ive cleaned the boast solenoid. whilst cleaning the boast noticed a frayed wire which is now snapped on the sensor thats next to the boast solenoid and the waste gate sensor so off to the electrican we go hopefuly this will be the problem. let you know the out come. if it wernt for cleaning the boast solenoid wouldnt have noticed it. let you no the out come.

Sounds like you are onto something there mate - IRC the sensor next to the Boost Solenoid is the MAP sensor. It certainly won't do the car much good if the sensor wire is damaged
