Check Input Shaft Speed Sensor Circuit
1)
Disconnect TCM connectors with ignition switch OFF.
2)
Check for proper connection to input shaft speed sensor at “E122-6” and “E122-16” [A] or “E124-5” and “E124-17” [B] terminals.
3)
If OK, check resistance of sensor circuit.
Resistance of sensor circuit
Resistance between terminals “E122-6” and “E122-16” [A] or “E124-5” and “E124-17” [B] of disconnected harness side TCM connector: 560 – 680 Ω at 20 °C (68 °F)
Continuity between terminal “E122-6” / “E122-16” [A] or “E124-5” / “E124-17” [B] of disconnected harness side TCM connector and ground: No continuity
Are check result satisfactory?
|
Go to Step 4.
|
Go to Step 3.
|
3 |
Inspect Input Shaft Speed Sensor
Inspect input shaft speed sensor referring to
Input Shaft Speed Sensor Inspection
.
Is result satisfactory?
|
“YEL” or “BRN” circuit open or short.
|
Replace input shaft speed sensor.
|
4 |
Check visually input shaft speed sensor and direct clutch drum for the followings.
•
No damage
• No foreign material attached • Correct installation
Are they in good condition?
|
Intermittent trouble or faulty TCM.
Check for intermittent referring to
Intermittent and Poor Connection Inspection
.
If OK, substitute a known-good TCM and recheck.
|
Clean, repair or replace.
