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 (in park or neutral) until radiator fan comes on. Allow engine to idle. Test drive vehicle with A/T in "2" position or M/T in 2nd gear. Accelerate for 5 seconds using Wide Open Throttle (WOT). If temporary DTC P1106 does not reset, problem is intermittent. System is okay at this time. If temporary DTC P1106 resets, substitute known-good PCM, then recheck. If symptom or indication goes away, replace original PCM.
