Transmission Position Sensor/Switch: Testing and Inspection

Transmission Range Switch Test





1. Remove the transmission range switch harness connector (A) from the connector bracket (B), then disconnect the connector.

2. Check for continuity between terminals at the harness connector. There should be continuity between the terminals listed for each switch position.

In the P position, between terminals:
^ No. 1 and No. 3
^ No. 1 and No. 8
^ No. 3 and No. 8
In the R position, between terminals:
^ No. 1 and No. 9
In the N position and between terminals:
^ No. 1 and No. 3
^ No. 1 and No. 10
^ No. 3 and No. 10
In the D position, between terminals:
^ No. 1 and No. 2
^ No. 1 and No. 4
^ No.2 and No.4
In the D3 position, between terminals:
^ No. 1 and No. 2
^ No. 1 and No. 5
^ No.2 and No.5
In the 2 position, between terminals:
^ No. 1 and No. 6





3. If there is no continuity between any terminal, remove the transmission range switch cover, and disconnect the connector (A) at the switch (B).

4. Check for continuity between terminals at the switch connector (c). There should be continuity between the terminals listed for each position.

In the P position, between terminals:
^ No. 4 and No. 5
^ No. 4 and No. 6
^ No. 5 and No. 6
In the R position, between terminals:
^ No. 1 and No. 4
In the N position, between terminals:
^ No. 4 and No. 5
^ No. 4 and No. 7
^ No.5 and No.7
In the D position, between terminals:
^ No.2 and No.4
^ No. 2 and No. 10
^ No. 4 and No. 10
In the D3 position, between terminals:
^ No. 4 and No. 8
^ No. 4 and No. 10
^ No. 8 and No. 10
In the 2 position, between terminals:
^ No.3 and No.4

5. If there is no continuity between any terminals, adjust the transmission range switch installation. If the transmission range switch installation is OK, replace the switch.

6. If the transmission range switch continuity check was OK, replace the faulty transmission range switch harness.
