Transmission Output Speed Sensor
- Ignition OFF, disconnect the OSS wiring harness connector X4 (2) from the control solenoid valve assembly.
- Ignition ON, test for 8.3-9.3 volts at terminal A.
- Ignition OFF, using the EL 35616
terminal test kit, connect the EL 38522
variable signal generator red lead to the OSS signal circuit terminal B on the TCM.
- Connect the black lead from the EL 38522
variable signal generator to ground.
- Set the EL 38522
variable signal generator to 5 volts, the frequency to 300 Hz and the percent duty cycle to 50 or the normal position.
- Ignition ON, verify with a scan tool the Transmission OSS parameter is between 256-266 RPM.
