Loose or dirty connectors may cause
intermittent loss of power to transmission
ECU and diagnostic codes to be logged.
Ensure that all connectors are clean and tight
before performing troubleshooting. Failure to
comply may result in incorrect test results.
(1) Check if main code 22 sub code 16 is
logged in WTEC II TEPSS (para 8-4).
(2) If main code 22 sub code 16 is logged,
WTEC II TEPSS has sensed a fault with
the output sensor or its circuit. Perform
Transmission System Troubleshooting
