How To Replace An Input Shaft Speed Sensor or Mainshaft Speed Sensor P0716 / P0717 / P0718

Today we're showing how to replace an automatic transmission input shaft speed sensor (or mainshaft speed sensor). This sensor works in conjunction with the output shaft (or countershaft) speed sensor and allows for normal, smooth transmission shifts. A faulty sensor will more than likely display the 'check engine light' on your vehicle's dashboard, hard shifting and an inoperable cruise control. It is possible to test the sensor, along with the PCM (power control module), but you need a very sophisticated and incredibly expensive scan tool to do so. P0716 - Input shaft speed sensor range/performance error. P0717 - Input shaft speed sensor no signal error. P0718 - Input shaft speed sensor intermittent failure error. ► Subscribe:    / carsntoys   ►► Tools and Supplies: Scan Tool: https://amzn.to/31lXxFl Multi-Meter: https://amzn.to/2KOdFZD Alligator Clips: https://amzn.to/2AQot3H Safety Glasses: https://amzn.to/2BQKZ05 ►► How to remove the splash guard:    • How To Replace All Exterior Lights and Bul...   (Forward to 4 minute mark) ►►► Our most helpful videos (One million + playlist):    • 1 Million Views Playlist   Note: Any attempt to repair automotive parts and/or systems carries risk of personal injury.
