Avensis 2010 D-4D warning lights on dash board


Recommended Posts


I am owner of a 2010 Toyota Avensis D-4D 150 hp. Two weeks ago five warning lights apear on my dash board. I have made a diagnostic and I get the folowing trouble codes: 

P1271-Fuel regulator valve

C1201-Egine control system malfunction

and  another two codes. One for electric parking brake and the other for ABS sensor right front weel.

I have changed the ABS sensor and erasing the error code.After tht the ABS problem was solved and I olso changed the common rail with that two sensors with a OM one and after I erased the faults after half an hour they apeared again with the same error codes beside ABS error that is solved. 

Olso after the errors apear engine loses power. 

I some of you guys have had this problem please help.

I've not had this experience, but if this happened to me I'd be using the diagnostic to monitor the rail pressure. What does it look like at idle and say 2000 rpm? I'm wondering if the scv is sticking or knackered. Ian
