P0108 Fault Code on 2002 GMC Duramax: Not Map Sensor - What Should I Do Next?

Model: Ck eng. light on Fault Code: P0108 Posted: 2015-02-16 15:10

I'm experiencing a P0108 diagnostic trouble code on my 2002 GMC Duramax. The code indicates an issue with the manifold absolute pressure (MAP) sensor, but I've confirmed it's not the MAP sensor itself. What are the next steps to diagnose and fix this problem?

Could the issue be related to the circuit wiring or signal connection? It's worth checking the electrical circuit, ground connections, and harness integrity to rule out a faulty sensor circuit rather than a failed MAP sensor.
