Can you tell me or show me a diagram of the location of the output speed sensor this vehicle please? Thank you. The car runs great in reverse, but when I put it in drive it hesitates and will not change gears, has no power to go. My scanner gave me the code P0721.
Do you
have the same problem?

Hi and thanks for using 2CarPros.

The output speed sensor is located in the transmission and requires the pan, filter and the valve body to be removed to access it. First, I'm going to provide the directions for removing the valve body and replacing the sensor after these directions.

____________________________________________________________________________________

VALVE BODY See pictures 1-4
Valve Body

- If still installed, remove oil filter. Refer to --> [ Oil Filter ] See: Fluid Filter - A/T > Removal and Replacement > Oil Filter.

Transmissions with Hydraulic Pressure Sensors:

- Carefully pull off the connectors for automatic transmission hydraulic pressure sensor 1 (G193) - 1 - and automatic transmission hydraulic pressure sensor 2 (G194) - 2 -.

Continuation for All

- Remove connector bolt - arrow -.

- Carefully release connector and pull off.

- The transmission fluid temperature sensor (G93) must be tightened to 10 Nm.

- Remove valve body bolts in diagonal sequence.

Tightening Specification: 8 Nm + 90 .

- Installation is performed in the reverse order of removal.

- After installation, fill with ATF, check ATF level, and top off. Refer to --> [ ATF Level Checking and Filling ] See: Fluid - A/T > Procedures > ATF Level Checking and Filling.

- Remove the sensor from the transmission.

Thanks for the reply. After replacing the output speed sensor, the gear is still not selecting correctly, it will move from drive 1 to drive 5, and I don't really know what to do about this issue.

Hi and welcome back:

Did you check to see if new trouble codes are stored?

Let me know. Also, clear the old code and see if it comes back.
