My car is progressively going into low boost mode. I have the led "safe mode" monitors. At first it would go into LBM (low boost mode) after idle for a while on a hot day. Then, on the highway for about 20 minutes on a HOT day it would go to LBM. Now after about 10 minutes on a cold start, it goes into LBM. I started checking coolant temp. sensors with the ohm meter and checking over the harness for bad wires and connections. But I couldnt find in the toyota manuals what this one sensor does or how to check it. The only thing I can figure is its on of the many sensors that give the ecu the ok to boost. Anyways, I pulled on the wire (lightly) and it broke. So Im going to price one at toyota tomorrow. Can anyone confirm what sensor this is and what it does? Sorry for the long post. I thought you may need my reasoning for messing with the sensor. BTW its the sensor in the middle of the picture on the back of the block. Its suppost to have a single wire come out of the top and a connector. Thanks
