If somebody could help me to figure out what’s wrong with my car I would greatly appreciate it. I ran a diagnostic on my RX8 and it gave me the following codes. These are the codes it’s giving me. No clue of what VSPG signal is. Could the intake valve control circuit low be that the secondary shutter valve is dirty and stuck open/closed?? And is the bank 1 sensor 1 code the upstream 02 sensor? (The one before the cat converter)
P0076: the solenoid that controls the VDI valve in your lower intake manifold is bad or has a problem between it and the PCM. This is an electrical problem, not a mechanical one. The solenoid is mounted to the back side of the upper intake solenoid. Check that it's connected properly. If it is, check for continuity between it and the PCM. If that is fine, replace the solenoid. DTC P0076
P0037 and P0130: the front O2 sensor (before the cat) appears to be bad. Could also be a wiring problem between it and the PCM. Same troubleshooting as above only with the O2 sensor instead of the solenoid. DTC P0130 DTC P0037
