ISSUE:

Diagnostic Trouble Codes (DTCs) P0705, P0708, P1704, and/or P1705 may be stored in memory. This may be caused by the Powertrain Control Module (PCM) reading an unexpected bit pattern for manual lever position. This may be caused by the PCM, the wiring harness, the connectors, and/or the Digital Transmission Range Sensor (DTRS).

ACTION:

Diagnose the cause of the failure by following the detailed Service Procedure in this TSB article and Figure 1.




Figure 1 – Article 98-23-12

SERVICE PROCEDURE

  1. Connect the New Generation Star (NGS) Tester to the vehicle and call Parameter Identification Displays (PIDs) TR, TR_D, and TR_V.
  2. Move the transmission range selector lever into each gear and stop.
  3. Observe the PIDs while wiggling the harness, tapping on the sensor, and/or driving the vehicle.

    Use PIDs TR, TR_D, and TR_V for codes:

    • P0705 – The computer saw a bit pattern which is not in the chart (Figure 1)
    • P0708 – The voltage for TR3A (displayed in TR_V) was higher than 1.8V
    • P1704 – The computer saw an in-between position when the test was initiate d
    • P1705 – The computer did not see 0000 (P) or 0110 (N) when the test was initiated
  4. Compare the PIDs to the chart in Figure 1.
