(Fixed Frequency) (Fixed Frequency) at 65 to 200 Hz. Then the
positive or negative side of the wave is widened or narrowed to control
the TCC pressure. The Pulse-Width has a duty-cycle in percentage.
90% DC = full operation 10% = almost OFF. Use a duty-cycle meter to
test signal. DO NOT apply steady power to this unit. This is a low
resistance unit and will get damaged by steady power application. Use
a turn-signal flasher in series with the solenoid to test. This will reduce
current allowing you to test the unit. This unit is POWER controlled by
the TCM or PCM at pin 2. The GROUND is taken from the solenoid body
itself.
TCC PWM Resistance = 15 to 28 Ohms
MAX CURRENT = Do not apply steady power. Low resistance unit.
Electronic Pressure Control Solenoid (LPS) or Linear Throttle
Pressure Control Solenoid
The Electronic Pressure Control Solenoid (LPS) also called the Linear
Throttle Pressure Control Solenoid (Honda and Acura) for the
M5HA/M5DA transmission is a PWM or Pulse Width Modulated unit.
PWM is a ratio of On to OFF. A 90% Duty-Cycle means that the unit is
ON 90% of the time, therefore, there will be high trans-fluid pressure.
The TCM provides both POWER and GROUND to control the unit. The
TCM varies the duty-cycle to the solenoid at a steady frequency. Do
not apply steady power to this solenoid or damage will result. This is a
low resistance unit. Use a turn-signal flasher in series with the unit
when testing. This will pulse and restrict power, preventing damage.
EPC RESISTANCE: 3 to 6 Ohms
MAX CURRENT: Do not apply steady power. Current depends on duty-
cycle.
