Intermittent fault, signal too low

Intermittent fault, signal too low
Checking cables
Check engine control module (ECM) and atmospheric pressure sensor connectors for contact resistance and oxidation according toru-RU0900c8af80854dc2#KC01108670.Check for loose or damaged terminal pins.
Check engine control module (ECM) and atmospheric pressure sensor connectors for contact resistance and oxidation according toru-RU0900c8af80854dc2#KC01108670.
Check for loose or damaged terminal pins.
Check signal cable between engine control module (ECM) terminal 18 and atmospheric pressure sensor terminal 3 for an intermittent short-circuit to ground and remedy according toru-RU0900c8af80854dc2#KC01107969and for an intermittent open-circuit according toru-RU0900c8af80854dc2#KC01108668.
Check signal cable between engine control module (ECM) terminal 78 and atmospheric pressure sensor terminal 1 for an intermittent open-circuit and remedy according toru-RU0900c8af80854dc2#KC01108668.Supply voltage should be 5 V.
Check signal cable between engine control module (ECM) terminal 78 and atmospheric pressure sensor terminal 1 for an intermittent open-circuit and remedy according toru-RU0900c8af80854dc2#KC01108668.
Supply voltage should be 5 V.
If no faults are found in the above fault-tracing try a new air conditioning (A/C) pressure sensor.
Other information:
To connect the test box, seeru-RU0900c8af8091550a#KC01601498.
To replace the air conditioning (A/C) pressure sensor, seeru-RU0900c8af8049ade4#KC01395194.
