Diagnostic Trouble Code(DTC) P0715

Input Speed Sensor(ISS) Circuit Malfunction

Circuit Description

Information relative to transaxle input speed to the TCM. The TCM uses transaxle input speed information to control line pressure, TCC apply and release and transaxle shift patterns. This information is also uses to calculate the appropriate operating gear ratios and TCC slippage.
The input speed sensor mounts onto piston B that is inside of valve body.
An air gap of 1.8~2.2mm(0.07~0.086inch) is maintained between the sensor and the piston B.
The sensor consists of a permanent magnet surrounded by a coil of wire. As the piston B is driven by the turbine shaft, an AC signal is induced by the input speed sensor. Higher vehicle speeds induce a higher frequency and voltage measurement at the sensor.
Sensor resistance should measure between 825~835 ohms at 20°C(68°F). Sensor can measure from 1,000~8,000HZ.

Diagnostic Trouble Code(DTC) P0720

Output Speed Sensor(OSS) Circuit Malfunction

Circuit Description

The vehicle A/T OSS is a magnetic inductive pickup that relays information relative to vehicle speed to the TCM.
Vehicle speed information is used by the TCM to control shift timing, line pressure, and TCC apply and release.
The output speed sensor mounts in the case at the speed sensor rotor, which is pressed onto the spur gear. An air gap of 0.1mm~1.3mm(0.004~0.05in) is maintained between the sensor and the teeth on the spur gear teeth. The sensor consists of a permanent magnet surrounded by a coil of wire. As the differential rotates, an AC signal induces a higher frequency and voltage measurement at the sensor. Sensor resistance should measure ∞ at 20°C (68°F). Sensor can measure from 20HZ~8,000HZ.
