the p0507 is for the idle air control(i a c) isnt working as it should. possible causes are:
The car has a vacuum leak,
Carbon buildup in the Throttle Body air passages
Defective Coolant Temperature Sensor
Defective Charging System/Alternator
Defective Power Steering Pressure Switch
The iac unit isnt working properly.
now the other two are for the trans. p0745 is for the pressure control solenoid malfunction.
check your transmission fluid if it is low and or dirty.
p0795 is for the pressure control solenoid valve "c". it could have to do with the transmission fluid as well. but if you do a transmission flush and service, this might help it. if it does not, a blockage inside the lines or the transmission its self, or the transmission is going bad.
