Checking the connectors and cables
Check the climate control module (CCM) and air quality sensor connectors. Check for contact resistance and oxidation. Check for loose connections.
Check the cable between control module terminal #B3 (#3) and air quality sensor terminal #3. Check for an intermittent open-circuit. Check for an intermittent short-circuit to supply voltage.
Check the cable between control module terminal #B5 (#5) and air quality sensor terminal #5. Check for an intermittent open-circuit. Check for an intermittent short-circuit to supply voltage.
Check the cable between control module terminal #B16 and air quality sensor terminal #1. Check for an intermittent open-circuit. Check for an intermittent short-circuit to ground.
