DTC P1106: Barometric Pressure (BARO) Sensor Circuit Range/Performance Problem

Perform PCM reset procedure. See PCM RESET PROCEDURE/CLEARING CODES  under SELF-DIAGNOSTIC SYSTEM. Start engine and hold it at 3000 RPM, with no loads and transmission in Park or Neutral, until cooling fan comes on. Let engine idle. Connect SCS service connector. Test drive vehicle with transmission in "2" (A/T) or 4th gear (M/T). Accelerate at wide open throttle for 5 seconds. If DTC P1106 resets, substitute a known-good PCM and recheck. If DTC does not reset, replace original PCM. If DTC P1106 does not set, problem is intermittent. System is okay at this time.
