TROUBLESHOOTING
Step
1 Was "A/T DIAGNOSTIC FLOW TABLE" in this
section performed?
2 Output shaft speed sensor circuit check:
1) Remove TCM cover.
2) With ignition switch OFF, disconnect TCM
connectors.
3) Check for proper connection to output shaft
speed sensor at E202-4 and E202-16 terminals.
4) If OK, check resistance of sensor circuit.
Resistance between E202-4 and E202-16:
387 – 473 Ω (at 20_C (68_F))
Resistance between E202-4/E202-16 and
ground:
1 MΩ or more
Are check results satisfactory?
3 Output shaft speed sensor check:
1) With ignition switch OFF, disconnect output
shaft speed sensor connector.
