DTC 97

DTC 97:

Vehicle Speed Sensor Circuit:

CIRCUIT DESCRIPTION
The Powertrain Control Module (PCM) receives the vehicle speed sensor signal on CKT 400. The PCM processes this signal and sends it to the various components which use vehicle speed data through CKT 817.

DTC 97 WILL SET WHEN:
DTC 97 will set if the PCM detects the wrong voltage potential for 26 seconds on CKT 817.

ACTION TAKEN (PCM Will Default To):
DTC 97 will be stored in the PCM memory but will not turn "ON" the Malfunction Indicator Lamp (MIL).

DTC CHART TEST DESCRIPTION
Number(s) below refer to circled number(s) on the diagnostic chart.

1. If vehicle speed is indicated at this point, DTC 97 is intermittent. Refer to Vehicle Speed Sensor for detailed circuit description.
2. Use J 35616-A (connector test adapter kit) to probe PCM harness terminals so damage does not occur to the terminals.
Refer to Vehicle Speed Sensor for complete diagnosis of CKT 817.

DIAGNOSTIC AIDS
Inspect the harness and all related connectors including the PCM connections. These may cause an intermittent. Check for damaged or pushed out terminals.
