I just pulled the codes on my bonneville and got a 23 (IAT sensor, its unplugged), 31 (Park/Neutral Switch), and a 58 (??) Does anyone know what the code 58 means? It'* not in Techinfo so if anyone knows please post it, thanks.

What is the year and trim line?

I got a 58 today. PASS key fuel enable circuit. Is your key dirty?

Oh sorry, its a 92 SSE Supercharged. The key may be a littly dirty, I can clean it off... would that really matter though? Or would having a remote starter have anything to do with it since I'm not using the key to start it?

Did you install the remote starter? I'm wondering about the bypass for the resistor chip in the key.

No, it was professionally installed when the previous owner (my cousin) owned it.

ahh glad to finally know why I get code 58! I bypassed the passlock. Jet wanted $150 to bypass it in the chip for me... ouch.
