Hey all,

I've been trying to troubleshoot the following codes for a while now without much progress. It's a perplexing combination of faults. Any help figuring this one out would be greatly appreciated!

P0038 HO2S Heater Control Circuit High
P0108 Manifold Absolute Pressure/Barometric Pressure Circuit High Input
P0138 O2 Sensor Circuit High Voltage

Not sure if helpful, but before P0108 fault code appeared the P0038 & P0138 occurred approximately one week earlier. At this time the crank pulley began to fail, consequently the car promptly parked and then fixed at the dealership with the ATI super-dampener. The week before I took the car to MINI of SA for help troubleshooting. The diagnosis provided was fouled O2 sensors. As a result I replaced both myself along with installed at DT BPV however with no results.

What could be the cause for these faults? My ScanGauge II shows boost of 19.1-19.2 psi which the car cannot produce of course.

A bad sensor of some sort? A fouled catalytic converter? If beneficial significant modifications are listed in my signature below.

Once again, as I cannot say it too much, any help figuring this one would be greatly appreciated!!!

 

Check your fuses in your engine bay..prob is the blue 15 volt

 

I checked each fuse and all of the links were good.

Does anybody have other suggestions? Thanks.
