DESCRIPTION
Some vehicles may exhibit diagnostic trouble codes (DTCs) P0720 or P0722 DTC and harsh engagement or shifts or starts in 5th gear from a stop.
These conditions may be caused by an open circuit in the output shaft speed (OSS) sensor or the solenoid body lead frame.
P0720 / P0722: Insufficient input from 055 sensor
Customers having this concern should have their vehicle repaired using the following repair procedure.
REPAIR PROCEDURE
1. Verify customer concern.
2. Check the condition of the transmission fluid.
a. If the fluid does not smell burnt, continue to step 2 and follow the repair procedure to diagnose the 055 circuit.
b. If fluid smells burnt, follow normal MS3 online instructions or Workshop Manual for diagnosis to repair.
3. Follow PINPOINT TEST 3: OUTPUT SHAFT SPEED (OSS) SENSOR on M53 or the Workshop Manual section 05-01.
a. If instructed to replace the OSS sensor in PPT step 9, proceed to Step 4.
b. If the PPT does not lead to replacing the OSS, this procedure does not apply. Proceed with normal diagnostics.
4. Check the build date on the solenoid body lead frame. The solenoid body lead frame build date is a Julian date - the first two numbers are the year
(09) and the next three numbers are the day of the year.
