Installation Notes and Tips

Verify connector style, mounting location, and calibration requirements before installation. On 1990-1995 Chevrolet Corvette applications, confirm the sensor is indexed correctly and that the throttle body linkage moves smoothly before final tightening. Clear diagnostic trouble codes and recheck throttle signal data after installation. Use the vehicle service information for any relearn or adjustment steps required by the engine control system.
