TROUBLESHOOTING
Step
1 Was "A"/T DIAGNOSTIC FLOW TABLE" in this
section performed?
2 Input shaft speed sensor circuit check:
1) With ignition switch OFF, disconnect TCM
connectors.
2) Check for proper connection to input shaft
speed sensor at E202-5 and E202-17 terminals.
3) If OK, check resistance of sensor circuit.
Input shaft speed sensor resistance:
Resistance between E202-5 and E202-17:
560 – 680 Ω (at 20_C (68_F))
Resistance between E202-5/E202-17 and
ground:
1 MΩ or more
Are check results satisfactory?
3 Input shaft speed sensor check:
1) With ignition switch OFF, disconnect input shaft
speed sensor connector.
2) Check for proper connection to input shaft
