Starts fine. Will not go into gear without using the shift lock release button. Shifts are rough. Engine light is on and shows code 'P1106 probable cause ECM'. Do I need to change the PCM or can I check other things first? Fuses, sensors etc? How do I test PCM before having to buy one? Also, can I change PCM without any fear of air bag problems?
Thanks,

Hi Dan523,

Here are the description and diagnostic procedures.

DTC P1106: BARO SENSOR RANGE/PERFORMANCE PROBLEM
Perform PCM reset procedure.
Start engine and run at 3000 RPM with no loads and transmission in Park or Neutral until radiator fan comes on.
Allow engine to idle.
Connect SCS Service Connector.
Test drive vehicle with transmission in "2" position (A/T) or in 4th gear (M/T).
Accelerate for 5 seconds with Wide Open Throttle (WOT).

If DTC P1106 is not indicated, problem is intermittent. System is okay at this time. If DTC P1106 is indicated, substitute a known good PCM and recheck. If symptom or indication goes away, replace original PCM.

Replacement of the PCM does not interfere with the air bags but remember to wait a few minuites after disconnecting the battery before starting with work.
