Signal too low

Checking components and wiring
Check the signal cable between gas pressure sensor connector terminal #2 and rear electronic module #B16 (#A36). Check for a short-circuit to ground. Check for an open-circuit.
Check the signal cable between gas pressure sensor connector terminal #4 and rear electronic module #C2 (#A42). Check for a short-circuit to supply voltage. Check for an open-circuit.
Check the connector for the gas pressure sensor. Check for oxidation or damage.
Remedy as necessary.
