Pinpoint Test D : Input Shaft Speed Sensor 1 Or 2 Fault: Notes
Refer to Transmission Controls for schematic and connector information.
Normal Operation and Fault Conditions
ISS sensor 1 measures the input speed and the rotating direction of input shaft 1. The input shaft can be stationary. Therefore, it is necessary the sensor system detect the stationary state of the input shaft accurately. By being stationary the sensor must not indicate speed unequal to 0 (also not, if the motor runs by high speeds). The slow rolling of the car has to be detected safely. ISS sensor 2 measures the input speed of input shaft 2. The rotation direction is not measured.
DTC Fault Trigger Conditions
| DTC | Description | Fault Trigger Conditions |
|---|---|---|
| P06A6 | Sensor Reference Voltage "A" Circuit Range/Performance | ISS sensor 1 power supply circuit failure. |
| P0715 | Turbine/Input Shaft Speed Sensor "A" Circuit | ISS sensor 1 circuit failure detected. |
| P06A7 | Sensor Reference Voltage "B" Circuit Range/Performance | ISS sensor 2 power supply circuit failure. |
| P0716 | Turbine/Input Shaft Speed Sensor "A" Circuit Range/Performance | Erratic ISS sensor 1 signal - noisy signal, out of range high, or not plausible. Detection of this fault is disabled if a power supply P06A6 or circuit fault P0715 is present. |
| P0717 | Turbine/Input Shaft Speed Sensor "A" Circuit No Signal | ISS sensor 1 failed to 0 speed when vehicle conditions indicated the input shaft speed should be non-zero. Detection of this fault is disabled if a power supply P06A6 or circuit fault P0715 is present. |
| P0718 | Turbine/Input Shaft Speed Sensor "A" Circuit Intermittent | This DTC sets along with P06A6, P0715, P0716 and/or P0717. Used to turn on the wrench light. |
| P2765 | Input/Turbine Speed Sensor "B" Circuit | ISS sensor 2 circuit failure detected. |
| P2766 | Input/Turbine Speed Sensor "B" Circuit Range/Performance | Erratic ISS sensor 1 signal - noisy signal, out of range high, or not plausible. Detection of this fault is disabled if a power supply P06A7 or circuit fault P2765 is present. |
| P2767 | Input/Turbine Speed Sensor "B" Circuit No Signal | ISS sensor 1 failed to 0 speed when vehicle conditions indicated the input shaft speed should be non-zero. Detection of this fault is disabled if a power supply P06A7 or circuit fault P2765 is present. |
| P2768 | Input/Turbine Speed Sensor "B" Circuit Intermittent | This DTC sets along with P06A7, P2765, P2766 and/or P2767. Used to turn on the wrench light. |
