Temperature Sensor Current
Always inspect wiring harness connectors that are involved in the circuit.
Is Below Normal
Poor connections can often be the cause of a problem in an electrical
circuit. Verify that all connections in the circuit are clean and secure and
that all connections are in good condition. If a problem with the
connection is found, correct the problem and verify that this malfunction
or diagnostic code is active before performing this procedure.
Perform open or short-circuit test at each wiring harness connection to
identify the correct wiring harness to replace.
Tag all wiring harnesses to aid in installation.
Perform this test only if condition is active.
DIAGNOSTIC CODE SET CONDITION
Transmission ECM detects current of torque converter temperature sensor is
below normal.
POSSIBLE CAUSE
Torque converter temperature sensor is faulty.
Lower cab wiring harness is open.
Transmission wiring harness is open.
Cab ground is open.
Transmission ECM.
Test Step 1. Check for Active
Diagnostic Codes.
Connect MSD. Select Transmission
Diagnostic Code 826-5 Active -
Proceed to Test Step 2.
924H and check for active diagnostic
codes (WP 0008).
Diagnostic Code 826-5 Not Active -
Troubleshooting is complete.
Test Step 2. Test for Faulty Torque
Converter Temperature Sensor.
1. Turn ignition switch and battery
disconnect switch to OFF position
(TM 5-3805-298-10).
2. Remove left engine access panel
