Checking the wiring
Check the power supply cable between control module terminal #A39 (#A39) and mass air flow (MAF) sensor terminal #4. Check for a short-circuit to ground.
Check the power supply cable between control module terminal #A39 (#A39) and boost pressure sensor terminal #3. Check for a short-circuit to ground.
Check the power supply cable between control module terminal #A39 (#A39) and air conditioning (A/C) pressure sensor terminal #3. Check for a short-circuit to ground.
HINT: Read off the voltage of the 5-volt power supply by clicking on the VCT2000 symbol.
Remedy as necessary.
