i have 2.5 2007 imprezia engine in 84 westy. car ran great then went to limp home mode. sub dealer code read crankshaft sensor. replaced sensor no improvement. found that ecu was only putting out 1 volt to sensor. replaced ecu with spare still only 1 volt coming out of ecu instrad of five volts. i had recently hooked up rpm gauge but it had run fine with it connected. checked alternator its fine. any suggestions where to look next. bus had run perfect before had also swapped out vss just in case but was not the problem. need advice thanks henry
