Pulled some CEL codes, any ideas ?

[rocafellafw]

Searched a little could not find any answers, only threads with no fixes.

P1105 - FPS Fuel Pressure Solenoid Circuit Fault:
I have my FPS hooked up in stock form (IM nipple to FPS, FPS to FPR) just do not know why the code would pop up ?

P0120 - Throttle/Pedal Position Sensor/Switch A Circuit Malfunction:
I suspected my TPS was bad due to a stuttering issue I was having, if it was bad would this be the code that would tell you ?

P0300 - Random Cylinder Misfire:
I have a 6-bolt swap with the inverted CAS that has the pigtail wires (No Plug). My plugs/wires are brand new and look perfect, have not done a compression/leakdown test yet but would the 6-bolt swap/CAS mixture be the reason behind this ?

o2 Sensor heater circuit Malfunction Bank 1 Sensors 1 & 2:
Was 95% sure my o2 sensors were bad, have new OEM's right next to me, this most certainly means they are bad correct ?

1. The ECU checks the solenoids by activating them briefly when you first start the car, and then it watches for an inductive kickback from the solenoid coil when it is de-energized to make sure the coil in intact, and that the wiring is good. Have you check the electrical connector to the solenoid? Have you checked the resistance of the solenoid with an ohmmeter?
2. I assume that when you did the 6-bolt swap you took the 2G TPS and installed it on your 1G throttlebody, right? Did you properly recalibrate the TPS after the swap?

3. The 1G cam sensor isn't as accurate as the original 2G sensor, so you will get Random Misfire MILs if you don't have one of my chips, or DSMLink, or do the hack mentioned in the Magnus 1gina2g.pdf. Their cheat is to install a potentiometer in the barometric pressure sensor wire to the ECU, and move the voltage just outside the range where the ECU will do the Random Misfire tests. This does slightly lean the car out, so be careful that you don't go too far, which can also cause another MIL.

4. That's very odd for you to have the heater circuits of both your O2 sensors burn out at the same time. The MIL's can also be caused by the +12 volts that supplies the heaters to be missing.

Thanks for the response. I will go over the entire FPS system and double check the lines. I myself did not do the swap the previous owner did, I have a new TPS I'm going to calibrate and see if it fixes that code. Next I can check the power line that supplies o2 sensors, if that does not work I was going to replace the sensors anyway. These codes did not all come at the same time (most likely not even around the same time) I just recently fixed the problem I was having getting a connection to my obd port so this is the first time I ever pulled codes, the CEL was on long before I had the car. Thanks again !
