Dodge Neon 2001 - OPERATION; REMOVAL; INSTALLATION

OPERATION
The Input Speed Sensor provides information on
how fast the input shaft is rotating. As the teeth of
the input clutch hub pass by the sensor coil (Fig.
291), an AC voltage is generated and sent to the
TCM. The TCM interprets this information as input
shaft rpm.
The TCM compares the input speed signal with
output speed signal to determine the following:
• Transmission gear ratio
• Speed ratio error detection
• CVI calculation
The TCM also compares the input speed signal and
the engine speed signal to determine the following:
• Torque converter clutch slippage
• Torque converter element speed ratio
REMOVAL
(1) Disconnect battery negative cable.
(2) Remove air cleaner/throttle body assembly.
(3) Disconnect input speed sensor connector.
(4) Unscrew and remove input speed sensor (Fig.
292).
(5) Inspect speed sensor o-ring (Fig. 293) and
replace if necessary.
INSTALLATION
(1) Verify o-ring is installed into position.
(2) Install and tighten input speed sensor to 27
N·m (20 ft. lbs.).
(3) Connect speed sensor connector.
(4) Install air cleaner/throttle body assembly.
(5) Connect battery negative cable.
