Hi
Has anyone had a problem or heard of a problem with toyota d4d engines going into limp mode with no power or acceleration and engine warning light on.
The car displayed obd2 error code p1250 on data scan tool. I had to erase it and drive the car 2 hours back to town.
Toyota said it could be a few things and pinpointing the problem will be difficult after i erased the code.
Any suggestions or answers would be great.
Thanks

P1250 Code - General
Turbocharger System Malfunction
OBD-II code P1250 indicates a problem with the turbocharger system on your vehicle.
On vehicles equipped with turbocharger systems, this code can indicate a problem within the system that is causing it to not function as it should. Turbochargers are meant to increase the efficiency and power of your vehicle. This code usually means that there is an over boost situation happening, but it can also mean the opposite. A problem with the turbocharger system will often cause a major loss in power and acceleration. The code is prompted by a malfunction which is then stored in your vehicle's ECM and causes the SES or
check engine soon light to illuminate on your dash.
Common causes of this code include:
Faulty vacuum sensing valve
Stuck turbo wastegate actuator
Faulty SCV valve
Wiring leading to the system
Diagnosing the exact problem when there is a turbocharger system malfunction might be tricky. Before you tackle any of these possible culprits,
check all of the wiring around the system for signs of damage. The easiest problem to start with is the wastegate actuator; this can be serviced by unbolting it and making sure the linkage is freely moving and the system is properly lubed. The vacuum sensing valve will throw the system off and cause the ECM to be "confused" about regulating the system, same with the SCV valve issues.

Yeah i read that too. And toyota mentioned as
well, but im thinking they tell me to replace the turbo or replace the stepper motor.
I suppose I am wondering should i be worried about it or see if it happens again before i spend money on replacing parts. I was driving in 40 deg + and doing about 100ks in cruise control when it shut down. So im hoping the air was too hot or something like that and all will be good.
I Used to own an 80 series so not used to having problems.
