DTC P1106: Barometric Pressure Sensor Range/Performance Problem

Perform PCM reset procedure. See PCM RESET PROCEDURE/CLEARING DIAGNOSTIC TROUBLE CODES  under SELF-DIAGNOSTIC SYSTEM. Start engine and run at 3000 RPM, with no load and transmission in Park or Neutral, until radiator fan comes on. Allow engine to idle. Test drive vehicle with transmission in "2" position. Accelerate for 5 seconds using Wide Open Throttle (WOT). If DTC P1106 does not reset, problem is intermittent. System is okay at this time. If DTC P1106 resets, substitute known-good PCM, then recheck. If symptom or indication goes away, replace original PCM.
