2003 trailblazer LT service engine soon
Hello all i have an issue with my 2003 TB I just bought it and it ran fine. I did an oil change and changed the air filter(very dirty) cleaned the throttle body with throttle body cleaner and now i have 3 codes. PO105 Map/Baro circuit malfuction, and two PO1345 manufactuer control ing. system or misfire.
I did the same thing on a 2002 TB that i just sold and it didn't do this.
Any ideas on what i could do?

Could it be the sensor in the air intake tube that i disconnected to clean the throttle body. What is it called?
