C1135 – OBD-II DTC

OBD-II DTC C1135 – Gear Shift position short to battery

DTC C1135 meaning

DTC C1135 refers to a diagnostic trouble code indicating a “Gear Shift Position Short to Battery” issue. This code is generated when the vehicle’s onboard diagnostic system detects an abnormal voltage signal from the gear shift position sensor, suggesting that the sensor is shorted to the battery voltage. This can affect the transmission’s ability to determine the correct gear position, leading to potential operational issues.
