driver while press lock (L2), and then
pull out connector (1) toward you.
2. Pull lock type (PACKARD-2)
q 107 – 170, 12V140 engine
q Various temperature sensors
Example)
Intake air temperature sensor in
intake manifold: TIM
Fuel temperature sensor: TFUEL
Oil temperature sensor: TOIL
Coolant temperature sensor: TWTR,
etc.
Disconnect the connector by pulling lock
(B) (on the wiring harness side) of connec-
tor (2) outward.
