Hi, the car has codes p0105 and p1105. I tested both sensors and they are good. Hoses and harness connections are also good. The car is running fine. Has anyone had this problem? Please help if you can.

 

Did you check the sensors by following the FSM? Codes don't show up for no reason, so something is not correct.

The P1105 (MAP/BARO sensor) gets confused with the sensors right next to it, so there is the possibility of you checking the wrong one. The P0105 (Absolute Pressure sensor) doesn't have this identity problem.

But these 2 sensors are interlinked. The vacuum for the absolute pressure sensor goes through/comes from the MAP BARO sensor (or visca versa).

 

thanks, where can I find the FSM?

 

Some members like Fakie Farkerton and Asand1 have FSM links

 

The Wizard has an FSM link.
