P0706
TRANSMISSION RANGE SENSOR - P0705/P0706The rotary switch is located on the LH side of the transmission. The harness incorporates the transmission wiring and runs into the car through the a hole in the LH side of the tunnel. The connectors GB001 and GB002 are located on the side of the selector mechanism "J" gate assembly.
Transmission Range Sensor Circuit - P0705
This test is performed continuously by the background diagnostics during operation. The test is a plausibility check on the 3 bit Gray code. The test criteria is that an invalid code must not be seen. If a Z code is seen for more than 100 ms, then this fault code will be stored and the transmission will adopt the default function.
Transmission Range Sensor Circuit Range/Performance - P0706
This is a plausibility check on the 3 bit Gray code which is only performed once during cranking when the engine speed reaches a specific threshold. If the gear is not P or N when this test is performed, then this fault cede will be flagged and the transmission will adopt the default function.
Rotary Switch (GB002)
PIN 1 - SWITCH COMMON
PIN 2 - CODE X OUTPUT
PIN 3 - CODE Y OUTPUT
PIN 4 - CODE Z OUTPUT
