hello have 02 xg350 with multiple codes , no power , start fine idle alittle high
like 1500 rpms press accelerator no power multiple codes present
po123-po113-po120-p1178-p1118-p1191-p1147-p1195-p1151
whant more
ck harness a little no power to throtle motor and clean codes and come on righ away what u think computer or harness

 

P0113 = Intake Air Temperature Circuit High Input
P0120 = Throttle Position Sensor/Switch A Circuit Malfunction
P0123 = Throttle Position Sensor/Switch A Circuit High Input
p1118 = ETS Motor - Malfunction
P1147 = ETS Sub Accel Position Sensor 1 Malfunction
P1151 = ETS Main Accel Position Sensor 2 Malfunction
P1178 = ETS Motor Battery Voltage Open
P1191 = ETS Limp Home Valve On
P1195 = Limp Home - Target Follow Delay

If the TPS and ETS are good, I'd suspect the computer.

 

thanks will get a used computer and test . just for the record this car have two computer brains
one for engine and accesories
second for electronic throtle control
both are hard to get under the ashtray below middle console
find out the hard way.
thanks for the tip
probably test pedal posi sensor 2 brain boxes and tps from yard.

 

ok the problem is solved
the no power to the etc ecm #2 wire is comming from relay located next to steering colum on the left side the small one test continuity
no sensor was replaced after 4 days or 5 try to locate.
