Toyota Land Cruiser P0100;P0110;P1115;P1405

Hi all,

Maybe someone can help me with this combination of fault codes.

Car: Toyota Land Cruiser 3.0 D4-D (2001)

Driving symptoms:
- small flutuation on acelaration when motor is with almost no charge (i.e. cruising at a constant speed 50 mph on leveled road). This is more noticeable when the engine is still cold.
- If acelator is pressed (or driven always more than 25% pressed) the problem is not noticeble.
- If one mantains the car in the flutuating condition, the car can loose power (seams that this is the turbo "shutting off"). It returns to normal by it self just leting go of the gas pedal for a little bit, loosing some speed or gear down (this is the situation that brings up the fault codes described)

Notes:
- Smal flutuations do not generate fault codes.
- Doesn't happen when car is in neutral.
- When dismounting and mouting inntake (including turbo) the problem desapears and returns after some miles.
- Turbo was checked and seams ok

My opinion:
- MAF should be replaced

P0100 - Mass or Volume Air Flow Circuit Malfunction
P0110 - Intake Air Temperature Circuit Malfunction
P1115 - Ambient temperature (not sure! this is what the tool shows.)
P1405 - Turbo Pressure Sensor Circuit

what year is it?

2001

sounds good!

Hi nborges
I have exactly the same symthomes for 4 months and my dealer can not find the problem. Valves of the injectionpump had been replaced twice, but problem goes on. Air mass indicator was also replaced.
how did you solve it ?
