Fault Codes / Reset
I recently did a 600+ mile ride in my Turbo S in So. California and Arizona. The machine performed flawlessly (although the gas mileage was horrific!).
Upon returning to my home in Utah (6,500 feet MSL) I acquired a check engine light. Going to the diagnostics page I found a "SPN 1127 and FMI 31 = Boost Pressure Sensor". Further research shows a "DTC P1234 = Condition Exists"
So far, I've replaced my BOV (Diverter Valve) with an Aftermarket Assassins BOV. Cleaned and blew out all connectors I could find. Cleaned sensor in the intake down stream of the air filter.
After reassembly, I drove the machine for about 10 to 15 minutes, getting it to operating temp and the check engine light still illuminates. I have tried disconnecting the batter for, oh, almost an hour. No joy.
My question: 1. Is this a hard fault that must be reset with an ECU reader?
2. Is there a chance that the fault still exists?
3. I'm open to suggestions.
