STI engine into BC5 RS codes
Fault codes on JDM sti 02 engine.
Have recently done a full engine and loom swap. Into bc5 RS. Almost there boys Starts and runs, but has a lil pop and misfire . The configuration: Running with just down pipe, hardwired external fuel pump no FPC, the relay as trigger, the front 02 is new, it's position is at the bottom of the up pipe. Rear 02 is in down pipe. Running a rising rate fpr. And removed charcoal canister. Td05 with boost pill in the waste gate vacuum line. I'm getting the following codes: P1237 - fuel pump secondary circuit P1239 - exhaust control valve solenoid circuit low P0444 - evaporated circuit open P1230 - FPC malfunction P1235 - ?? Misfire? P1130 - air fuel circuit open bank 1 sensor 1 P1249 - ?? No idea P0249 - waste gate solenoid waste gate solenoid P1247 - ?? P1199 - Differential P1237 - fuel pump secondary circuit If anyone could take the time to check to see if my code IDs are correct and any info about how to fix my problem would be awesome. I just want major/important codes sorted not fussed about minor ones. As I know my setup of fuel pump etc is causing some of them.

What ECU are you running? That makes a big difference as to what the codes will mean.
P1249 is a wastegate control solenoid CEL, P1247 is Relief Valve Control Solenoid 1 Circuit Low, P1199 is a Differential Pressure Sensor, so likely tied to a pressure sensor between the intake and the manifold. Much of the rest is tied to not having a FPC or emissions equipment properly connected. |
