ru-RU0900c8af80918607#KC02451888
Checking signal cable
Connect an ohmmeter between the atmospheric pressure sensor connector terminal 3 (control module side) and the ground terminal.
The ohmmeter should read approximately 59 kΩ.
ru-RU0900c8af80918607#KC02451886
ru-RU0900c8af80918607#KC02451889
Checking ground lead
Connect an ohmmeter between the atmospheric pressure sensor connector terminal 2 (control module side) and ground.
The ohmmeter should read approximately 0 Ω.

Defective atmospheric pressure sensor
Try a new atmospheric pressure sensor according toru-RU0900c8af8049ad90#KC01400199.
Select "Continue".
Check cable between atmospheric pressure sensor connector terminal 1 (control module side) and engine control module (ECM) terminal 78 for an open-circuit according toru-RU0900c8af80be4147#KC01106360.
Check cable between atmospheric pressure sensor connector terminal 3 (control module side) and engine control module (ECM) terminal 18 for a short-circuit to ground according toru-RU0900c8af80be4147#KC01106352.
Check cable between atmospheric pressure sensor connector terminal 2 (control module side) and engine control module (ECM) terminal 77 for an open-circuit according toru-RU0900c8af80be4147#KC01106360.
Verification
Reconnect connectors, reinstall components.
Connect the VCT 2000.
Read the parameter ATM PR.
Is this reading OK?
