P0720

P0720 OUTPUT SPEED SENSOR MALFUNCTION (FROM VIN C 79329)
CHECK THE OUTPUT SPEED SENSOR GROUND CIRCUIT.
1. Disconnect the transmission electrical connector JB155.
2. Measure the resistance between JB155, pin 05 (B) and GROUND (shielded cable).
^ Is the resistance greater than 5 ohms?
-> Yes
REPAIR the high resistance circuit.
-> No

CHECK THE OUTPUT SPEED SENSOR GROUND CIRCUIT FOR CONTINUITY.
1. Disconnect the TOM electrical connector, JB131.
2. Measure the resistance between JB155, pin 05 (B) and JB131, pin 42 (B).
^ Is the resistance greater than 5 ohms?
REPAIR the high resistance circuit.
-> No

CHECK THE OUTPUT SPEED SENSOR SIGNAL WIRE FOR CONTINUITY.
1. Measure the resistance between JB155, pin 06 (N) and JB131, pin 05 (N).
^ Is the resistance greater than 5 ohms?
REPAIR the high resistance circuit.
-> No

CHECK THE RESISTANCE OF THE OUTPUT SPEED SENSOR.
1. Measure the resistance between JB155, pin 05 and pin 06 at the transmission.
^ Is the resistance 550 ohms?
-> Yes
Contact dealer technical support for advice on possible module failure.
-> No
INSTALL a new transaxle. CLEAR the DTC. TEST the system for normal operation.
