Hello guys,

After I cleaned my Throttle valve flapper and MAF I'm experiencing P1129 that is MAP sensor signal higher than expected.
I performed the test for the MAP sensor and got 5v going into the sensor by the wire #1, but for the middle wire or #2 I got really bad results in ground test, it is open no ground connection.
What I read is the ground is coming from the PCM. Any suggestion how to find the ground problem.
Do you know where can I get the PCM pinout diagram?

Best regards.-
