2 Check TCC solenoid valve resistance
1) Turn ignition switch OFF
2) Disconnect valve body harness connector
on automatic transmission.
3) Check for proper connection to solenoid at
“WHT/BLU” circuit.
4) Check resistance of solenoid valve. See
Fig.

terminals of transmission side valve body
harness connector: 11 – 15
Ω
at 20°C
