@smooch a failed MAP/Baro Switch solenoid can give you the same code. Check for more reasons for code P1105 on here If that solenoid does not open then your sensor does not get a vacuum and will read barometric pressure which will trigger this code. Check the solenoid by unplugging the vacuum hose on the sensor and attach a vacuum gauge to that. Start your car and within seconds your gauge should read a vacuum. If there is no vacuum then it is most likely that your solenoid has failed. Of course this will only work if your vacuum hoses are not cracked etc.
