Help with Codes P0102 and P0327?
2000 Chevy Silverado LT, 5.3 Vortec
Nelson Tune
Whipple blower with stock pulley
Throwing two codes,
1) P0102 - MAF/VAF circuit low
2) P0327 - Knock Sensor circuit (something like that)
Any insight anyone please?
California Smog now requires that any OBDII automobiles not have their SES light on during smog (according to the smog guy). I used to just hook up the scanner and dump the codes...

The SE light is everywhere with OBD 2 inspection

When you find the knock sensor harness, unplug it and gram an ohmmeter and test each sensor. They should be right at 100K ohms. If one is less than that you will have to replace it. Put one probe on the pin from the connector and the other try to touch the valley cover.
The plug for the knock sensors is on the back of the intake manifold by the firewall, and it has a little metal clip that holds it to the manifold. I think I posted in your other thread, but check out the Radix install instructions. They tell you how to pull the manifold and somewhere in there are pics of unplugging the knock sensors.
