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 the WTEC III TPSS (para 8-5).
(2) If main code 22 sub code 16 is logged,
WTEC III transmission ECU has sensed a
fault with the output speed sensor or its
circuit. Perform Transmission System
Troubleshooting (f24. WTEC III Transmission
Pushbutton Shift Selector (TPSS) Displays
Main Code 22 Sub Code 16).
