Check the connector of boost pressure sensor 2 (MAP) for contact resistance and oxidation as described in Contact resistance and oxidation and loose connections as described in Loose connections (terminals) . Check especially for damage.

Check the signal cable between boost pressure sensor 2 (MAP) terminal #3 and control module terminal #13 and the power supply cable between boost pressure sensor 2 (MAP) terminal #1 and control module terminal #74 for intermittent open circuit as described in Open-circuit, intermittent faults .

HINT: Boost pressure sensor 2 (MAP) is supplied 5 V from control module terminal #74.

Check the signal cable between boost pressure sensor 2 (MAP) terminal #3 and control module terminal #13 for intermittent short circuit to ground as described in Short-circuit to ground, intermittent faults .
