Transmission Position Sensor/Switch: Testing and Inspection
Inhibitor SwitchINSPECTION
When the driving condition or starter motor operation is improper, first check the shift linkage for improper operation. If the shift linkage is functioning properly, check the inhibitor switch.
1) Remove the air intake boot assembly.
2) Disconnect the inhibitor harness connector.
3) Check for continuity in inhibitor switch circuit by shifting the select lever in "P", "R", "N" and "D" respectively.
NOTE:
^ Check that there is no continuity in the ignition circuit when the select lever is in the "R" and "D" ranges.
^ When inhibitor switch is normal, check there is no poor contact in vehicle side connector and no open circuit in harness.
4) Check that there is continuity at equal points when the select lever is moved 1.5° in both directions from the "N" range.
If there is continuity in only one direction or in other points, adjust the inhibitor switch.
5) Repeat the above inspection in other gear ranges. If there is fault, adjust the inhibitor switch and select cable.
