Not sure where to start- this car is supercharged and left the shop OK about 2 months ago. Now it's in with P2227 "BARO sensor circuit range problem" and P2138 "TP sensor incorrect voltage correlation) We tried to relearn the throttle position as per Acura, but get the codes after a short, high speed drive. Any general tips or software updates that we should try before attempting anything drastic? (and time consuming) I'm hoping that a fellow Acura owner/tuner can shed some light on this-

thanks in advance- Steve

The Baro sensor could be something as simple as clamping the voltage on the sensor, but I'm not too sure why you would get a TPS fault. Is the TPS tapped?
