On the I-6, it's just above the oil filter.
Remove the shield plate to get at it.

Note, with all of the emission equipment on these trucks, it's now called an oil pressure sensor.

Compnine.com shows it as a "Switch, Engine Oil Pressure" and the AC Delco Part # is 12579946 listed as $45.

C.B.

The above is for 2003 year and I thought it would be the same. However, just checked and 2002 doesn't even show a sensor or switch!!!:worried:
