Posts: 66 Thanks: 3 Trader Rating: 0 ![]() | ![]() Hi, can anyone help?? I recently bought a 2001 1.9TD ELX 105 JTD which required a new turbo. One was duly fitted but the car remained in limp mode with high revs. The fault code P0236 Boost Valve Pressure appeared. My mechanic spoke to Fiat who advised a new MAF sensor, this was duly replaced but the car still remained in limp mode with high revs. The mechanic then followed ALL of the advice given previously on this forum with regards to code clearance but the problem remains. He then transported the car to Fiat for diagnosis and incredibly they said they had no idea what the problem was but it MAY be a faulty ECU, faulty map sensor or faulty turbo.... ![]() ![]() Many thanks in anticipation of help ![]()

According to the website : http://www.meat-doria.com/product_meat/82126 both MAPs can be fitted to the 110 JTD multipla, but only 46811235 appears for the 105 multipla.....but better check in case I missed it. .

Map Sensor or ECU fault?? the 105 jtd is a 186AXB1A, you should be able to confirm this by looking at your chassis/VIN plate, which is under the bonnet, underneath the fiat badge as you look at the front of the car. find the bit that says motore engine, and it should say 186AXB1A. failing that do what i did and google the two engine codes, the b1a comes up as a 105jtd, the e1a a 120. as an aside, have you tried replacing the turbo boost solenoid? might be worth getting one second hand. sorry you may have told us already in the other threads! if all of the info given on here has been followed then its looking like a wiring or ecu fault. find someone in your yellow pages that tests ecu's/automotive electronics and shop around a bit as prices vary. if your fiat dealer is friendly enough they might tell you who they use. im not sure i would agree with it being a common fault for the ecu to be faulty, i didnt replace one in ten years on fiat, but thats not to say it isnt. just a hunch mind!

Hope this helps
