Signal too low

Checking components and wiring
Check the signal cable between electronic throttle module (ETM) terminal #6 and engine control module (ECM) terminal #A6 (#A6). Check for an open-circuit. Check for a short-circuit to ground.
Check the signal cable between electronic throttle module (ETM) terminal #3 and engine control module (ECM) terminal #A43 (#A43). Check for an open-circuit. Check for a short-circuit to ground.
Check the power supply to electronic throttle module (ETM) terminal #5 from engine control module (ECM) terminal #A5 (#A5). Check for an open-circuit. Check for a short-circuit to ground.
Remedy as necessary.
