C1403 - Mailfunction in Rear speed sensor RH Circuit

Dear vister

First I will tell you why this error show in during scaning vehicle when the sensor is short it show circuit high in scanner and when the coil is week then it show circuit open or circuit low

When there was problem accured in communication with sensor and the magnetic gear if it provide low magnetic field or high magnetic field then is ECM do not able to point out the exact speed so it show the mailfunction in scanner

In vehicle there was problem in tire hub sensor gear which was not communicationg with sensor and was showing the sensor mailfunction
