Pulled these 2 codes today, no CEL came on. The P0190 is of course the Fuel Rail Pressure senor malfunction. And the P1233 is the Fuel Pump Driver Module off-line.
The car is running a Vortech supercharger w/ FMIC, Dragon plenum + throttle body, Magnaflow X-pipe and exhaust. The car seems to be running fine. Oil pressure (via the stock guage) is reading fine, a little on the high side. The aftermarket guage is ****ed up and only reads once in awhile.
I checked the FRPS sensor and it seemed clean, I don't have access to a voltmeter and may just go out and replace it.
But what about the P1233? Any ideas on how to remedy this one?
