Hi everyone,
Recently had some minor work done to my 21 ZL1 1LE. Headers, cat less Xpipe, CAI and flex fuel tune. This weekend, codes 129d and 12a6 came up on my P3 gauge. Anyone ever get these? I googled them and this is what I found: The Fuel Pump Power Control Module monitors the ignition voltage circuit to determine if the voltage is within the normal operating range. The Diagnostic Trouble Code (DTC) will be set when the Fuel Pump Power Control Module ignition switch circuit voltage is less than a calibrated value for 1 s.
