Component Testing
WARNING: This page is about a different car, the 2010 Pontiac G5 and 2010 Chevrolet Cobalt. However, it is still accessible from the selected car via links, so may be relevant.
Using a DMM, connect one lead to the PNP Switch ground circuit terminal 11, and the other lead to each of the following PNP Switch signal circuit terminals and compare the readings to the Transmission Range Switch Logic table for each gear selector position.
- Terminal 9
- Terminal 8
- Terminal 10
- Terminal 2
IMPORTANT:
A DMM reading of less than 10 ohms corresponds to LOW on the logic Table. A DMM reading of infinite resistance corresponds to HIGH on the logic Table.
- If not the specified value, replace the PNP Switch.
