Question about 1997 Mercedes-Benz C
Code po720 refers to output shaft sped (OSS) sensor---circuit malfunction ===causes wiring--OSS sensor ECM/TCM
the possible fixes here are the OSS and the TCM . It could be either or both so I would suggest a visit to an accredited auto transmission shop to test the units before spending money on a good unit.
