1998 Buick Regal 25th Anniversary EditionSECTION Circuit Description

Input speed sensor is a permanent magnet with a coil of wire wound around it. Sensor mounts in transaxle case facing drive sprocket on input shaft. An air gap of .003-.834" (.076-21.2 mm) between sensor and drive sprocket must be maintained to transmit an accurate AC voltage. Sensor voltage varies from .5 volt at 100 RPM to more than 100 volts at 6000 RPM. This DTC monitors ISS circuit. Circuit may be functional but not in normal operating range. DTC indicates stuck, erratic, or intermittent values, indicating poor system performance. ISS has a resistance value of 893-1428 ohms. DTC P0716 will set if PCM detects an unrealistically large change in data from ISS.
