Default Reduced Engine Power :(

I've been battling with a recent set of CEL's on my 2002 c5 z06.


These are the Codes im getting:


  • P1221 TP Sensors 1, 2 Performance
  • C1214 Sol Valve Relay Contact or Coil CKT Open
  • C1276 Delivered Torque Signal CKT Malfunction
    (I think these 2 require me to send out my abs board to absfixer)
  • B2252 Key Cylinder Switch Fault
  • B2265 Horizontal Position Sensor Fault



Not sure where to start on the TP sensor (Since I have a LS2 90mm tb); does the whole TB have to be replaced?

1214 is the relay in the EBCM- 2001 and later can be repaired cheap.
