Input speed sensor circuit check:
1) Remove PCM cover.
2) With ignition switch OFF, disconnect PCM
connectors.
3) Check for proper connection to input speed sensor
at C51-1-10 and C51-1-11 terminals for G16/J20
(at C51-1-8 and C51-1-16 terminals for H25)
4) If OK, check resistance of sensor circuit.
Resistance between C51-1-10
and C51-1-11 for G16 /J20
(C51-1-8 and C51-1-16 for H25):
530 – 650

Resistance between C51-1-10 /
C51-1-11 for G16 / J20 (C51-1-8 /
C51-1-16 for H25) and ground:
1 M
or more
Are check results satisfactory?
Go to Step 4.
Go to Step 3.

Input speed sensor check:
1) With ignition switch OFF, disconnect input speed
sensor connector.
2) Check for proper connection to input speed sensor
at each terminals.
3) If OK, then check resistance of input speed sensor.
Are measured values as specified in Step 2?
“Bl / G” or “Bl / Y” wire
open or shorted to
ground.
Replace input speed
sensor.

Check visually input speed sensor and overdrive clutch
drum for the followings.

Are they in good condition?
Intermittent trouble
or faulty PCM.
Check for intermittent
referring to
“Intermittent and
Poor Connection” in
Section 0A.
Clean, repair or
replace.
Reference
Connect oscilloscope between C51-1-11 (+) and C51-1-10 (–) for
G16 / J20 (C51-1-16 (+) and C51-1-8 (–) for H25) of PCM connector
connected to PCM and check input speed sensor signal.
