I have the manifold absolute pressure sensor code and can't get it to go away. I recently installed a new to me but used intake manifold due to short runner issue. I have swapped the sensor but still have the code. the clip on the harness is broken off but I have it zip tied to the sensor and it's tight.

I've scoured the internet and tried to find a new connector for it to no avail. Starting to think there could be something wrong with a wire for it but haven't started digging into the harness yet.

Anybody else had this issue before?

Load test the wires, make sure you're getting 5v to the connector, verify good & clean ground. If all that's good, then majority of wiring issues are eliminated. At that point, it's either pcm or sensor.

I'll try this tonight when I get home from work. I feel like I might have to get into the harness and trace the wires to see I can find a short somewhere. Also having to change out all the o2 sensors.
When plugged into diagnostic one sensor hangs up and others are reading good, then all of a sudden that one frees up and another freezes up. Seems very odd, but figured I'd change them out.
