TR Sensor

Testing the TR Sensor

Static testing procedures allow for shop testing of the transmission in the vehicle or on the bench. Completion of these tests prove out the TR sensor electronically.

Caution: For resistance checks, be sure that the tester select switch Is set to the "MLP SENSOR TEST" posItion or damage to the ohmmeter may result.

Resistance/Continuity Tests

^ Using a digital volt-ohmmeter and the transmission tester perform the pinpoint test "D" as indicated based on the DTCs which were displayed.

^ Perform repairs as indicated by the pinpoint test. Always retest and road test vehicle after a repair.

TR Sensor resistance tests

1. Set ohmmeter to 1,000 ohm range.
2. Connect the positive lead of the ohmmeter to the MLP jack.
3. Connect the negative lead of the ohmmeter to the SIGRTN jack.
4. Move selector lever into each range position.
5. Record resistance at each position.
6. Refer to chart for values.

If out of range refer to pinpoint test "D".
