Multiple codes p1289,P0715,P0340?

Question

Here are the codes I have received:
P1289 - Cylinder Head Temperature Senor Circuit High Input
P0715 - Turbine / Input Shaft Sensor A Circuit
P0340 - Camshaft Position Sensor A Circuit (Bank 1 Or Single Sensor)

Answer 1

P1289 CHT sensor circuit high input

P0715 Turbine ./ input sensor

P0340 Camshaft sensor

P0715 when this set this is a intermittent loss of the input sensor, circuit high codes are open circuit, what all these 3 code have in common are the same splice with the GY/RD wire, Run a KOEO (key on engine off test) this may be a fault with the EGR module, or if you have a EGR code , the problem would traced to the EGR module
