Hi new to the forum names Andrew i got a 03 cts got the car for $2000 dollars needed head gaskets and got the gaskets on. Then found the crank position sensor wires were burn so replaced it car started right up. Now the problem is bank 2 sensor 1 has a high voltage code and voltage is 1.085 and does not change even if i unplug the sensor still get 1.085 wires were also burn on the main harness side replaced burnt wires with good wire and bank 2 sensor 2 is getting codes p0056 and p0161. I am lost tryed everything swapped bank 1 with bank 2 still same problem. Any help is good just hoping the ecu is not bad
when i check the 02 plug with a test light only one wire is getting power and not getting a ground one min it will get no activity and heater codes and next its getting high voltage
