Outline
The TCM optimizes the hydraulic pressure for clutch engagement and disengagement through learning correction of the clutch engagement pressure.
NOTE:
The clutch engagement pressure learning value stored in the TCM is not cleared even if the negative battery terminal is disconnected. Therefore, if the control valve body is replaced, the learning value stored in the TCM and the control valve body specification are incompatible and engine rev-up may occur or shift shock may increase. Due to this, if the control valve body is replaced, it is necessary to perform the initial learning.
Construction
Operation
The TCM learns engine performance changes resulting from past shifting and deterioration over time of the transaxle and performs learning correction for optimum clutch engagement pressure during initial shifting.
Evaporative Emission (Evap) Control System
Purpose, Outline
Prevents release of evaporative gas into the atmosphere.
The intake manifold vacuum introduces evaporative gas to the intake manifold
via the charcoal canister and the purge solenoid valve.

Crankshaft Position (CKP) Sensor Removal/Installation
CAUTION:
When foreign material such as an iron chip is on the CKP sensor, it can cause
abnormal output from the sensor because of flux turbulence and adversely affect
the engine control. Be sure there is no foreign material on the CKP sensor when
replacing.
Do not assemble t ...
