For the 3rd summer in a row, i get the following error codes on my 2012 SAN 230. Code SPN 1079 sensor supply voltage and SPN 168 Vbat High. The first time the dealer said it was due to water sorting it out $330 repair, last summer said it was due to a faulty spark plug $300 repair, first time out this summer happened again. Any suggestiuons, is there a way to reset the sensor / warning? Tha
